Methylhexanamine in athletic performance -

Ashley Metcalfe, British Weight Lifting CEO said: Weightlifting is a fantastic sport, not least because of the health and wellbeing benefits associated with strength training.

Nicole Sapstead, UK Anti-Doping Chief Executive said: Any athlete who takes supplements containing DMAA in-competition — either deliberately or inadvertently - is not only risking their career, but is also risking their health.

Background The Medicines and Healthcare products Regulatory Agency MHRA is responsible for regulating all medicines and medical devices in the UK by ensuring they work and are acceptably safe.

All our work is underpinned by robust and fact-based judgements to ensure that the benefits justify any risks. MHRA is a centre of the Medicines and Healthcare products Regulatory Agency which also includes the National Institute for Biological Standards and Control NIBSC and the Clinical Practice Research Datalink CPRD.

The Medicines and Healthcare products Regulatory Agency is an executive agency of the Department of Health. The approach for the classification of Borderline products is set out in Part 9 of the Human Medicines Regulations as amended.

A borderline product is a product which does not have a relevant authorisation or registration that the Licensing Authority regards to be medicinal product.

Unless exempt unlicensed medicines may not be placed on the UK market without the appropriate authorisation. MHRA classifies products not substances according to the definition of a medicinal product. MHRA first classified a product containing DMAA to be medicinal products in MHRA has since determined a number of products which contain DMAA to be medicinal products and may not be placed on the UK market without the appropriate authorisation.

DMAA is regarded as being capable of significant modification to human physiology. Products containing DMAA have already been subject to regulatory controls in various countries around the world following a series of suspected links to serious adverse effects.

MHRA is responsible for ensuring that medicinal products work and are acceptably safe and is not responsible for the licensing of products such as sports supplements which are used by athletes to improve their performance.

MHRA will investigate instances of the sale and supply of unauthorised medicinal products, including those that may be present in sports supplements. Share this page The following links open in a new tab Share on Facebook opens in new tab Share on Twitter opens in new tab.

Following post-hospitalization analysis, Gee and colleagues attributed the cerebral hemorrhages to DMAA ingestion, noting that DMAA is structurally similar to amphetamines, which can cause cerebral hemorrhaging [].

The amount of DMAA ingested by individuals described in these reports was estimated to be approximately 15 to 30 times the amount provided in a usual serving of most dietary supplements containing DMAA. In addition, as noted in the papers of Gee and colleagues [9,10], other chemicals may have been taken along with the DMAA e.

Hence, the likelihood exists that the adverse events noted by Gee et al. The pills contained DMAA at an estimated dose of approximately mg based on labeled dose information lab analysis confirmed dosage of mg , a dose approximately times that normally suggested by most pre-workout dietary supplements.

In our prior work using a dosage of 50 mg and 75 mg of DMAA, we noted a dose-dependent increase in blood pressure. Specifically, we observed a mean increase in systolic blood pressure of 16 mmHg with the 75 mg DMAA dosage and approximately 24 mmHg when mg of caffeine was added to the 75 mg DMAA dose [4].

Ingestion of double this amount of DMAA by a young woman is extremely unwise, in particular with the co-ingestion of caffeine and alcohol. Another individual, a year-old man, also suffered a cerebral hemorrhage [10]. If consuming one quarter of the packet and assuming that said packet contained multiple dosages, it is possible that this individual consumed a very high quantity of DMAA.

When coupled with alcohol and nicotine, this indeed presents a potentially harmful combination. A year-old man was also highlighted in the Gee et al. report [10]. He collapsed 30 minutes later with a severe headache and upon analysis, it was noted that he also suffered a cerebral hemorrhage.

His blood DMAA levels were extremely high 2. At such a high dosage of DMAA, it is not surprising that the individual experienced an adverse outcome. The following day the patient reported to the ER and was found to suffer from a large hemorrhage in the region of the left basal ganglia.

Considering the above information presented by Gee and colleagues, one issue is clear and needs to be understood: individuals ingesting DMAA at extremely high dosages are subject to adverse outcomes likely involving elevated blood pressure and associated problems.

Considering that our work demonstrated a clear dose-dependent increase in blood pressure following DMAA use [4], with a mean increase in systolic blood pressure of 16 mmHg with a 75 mg dosage of DMAA, it is not surprising that adverse events are noted when individuals consume doses that are several fold higher.

Couple this with caffeine ingestion and the intake of alcohol and other drugs, and adverse events are likely. Individuals considering DMAA use, as well as healthcare providers, who may be providing care to such individuals, should understand the potential risks of using DMAA.

Like all stimulants, caution needs to be used as related to the total dosage ingested. Acute MI has also been associated with DMAA consumption. A case report by Smith et al. The authors reported that the man was otherwise healthy and presented none of the traditional risk factors for MI.

Three weeks prior to hospitalization, the man reported daily ingestion of a DMAA containing supplement, as well as another product containing Citrus aurantium , caffeine and other ingredients. With a lack of traditional risk factors, the authors speculated that the joint stimulatory effects of DMAA and Citrus aurantium caused the MI.

No information was presented regarding the dosage of supplements taken by the individual. As with many users of sports supplements, it is possible that this individual consumed more than the recommended serving size of each product.

If so, the caffeine intake alone could have been a few hundred milligrams. In such a case, it is important to raise awareness as to the potential for adverse events when individuals consume multiple stimulants, possibly at high dosages and in the context of strenuous exercise.

In a similar situation, Karnatovskaia et al. Again, the individual examined presented none of the typical risk factors for heart disease. However, the individual had consumed for the first time an unnamed pre-workout supplement that reportedly contained DMAA. With a lack of other risk factors present, Karnatovskaia and coworkers attributed the arrest to the consumption of DMAA.

No data were presented as to how much of the dietary supplement was consumed by the individual, including the quantity of DMAA. Moreover, no information was presented as to which other ingredients were contained within the supplement.

In almost all cases, pre-workout dietary supplements containing DMAA are formulated with multiple ingredients, including caffeine and additional stimulants. The caffeine content of these products is typically times that of DMAA e. This should be considered in the case analyses.

A series of case reports composed by Foley et al. All individuals were relatively young aged years , and none reported prior history of liver injury. All individuals reported ingesting the supplement at some point, either alone or in conjunction with other dietary supplements.

The range of intake of the supplement spanned from one week to three years. All individuals experienced liver injury, with the most common symptoms reported being jaundice, fatigue, exercise intolerance, abdominal pain and vomiting. A report composed by Roytman et al. The cases were severe, with one individual dying and two requiring liver transplants.

While six of the eight individuals highlighted in this paper had used the original OxyELITE Pro product containing DMAA, the authors focused more heavily on the potential cause of liver injury being an ingredient known as aegeline, contained within a reformulated version of the OxyELITE Pro, rather than DMAA.

Clearly, it is unknown what ingredient s may have been associated with the cases noted above. As with all multi-component products, it is difficult to determine the direct contribution of DMAA to the outcomes, as multiple other ingredients are contained within the OxyELITE Pro.

In two cases of alleged DMAA ingestion, one male and one female soldier collapsed during physical testing from suspected cardiac arrest and ultimately died [22].

These soldiers were reportedly ingesting dietary supplements containing DMAA. The authors indicate that the male soldier was taking only one dietary supplement, according to persons in his immediate community. The authors assumed that the female soldier was taking two dietary supplements containing DMAA, because the supplements were found in her car.

A recent report published in the Journal of the American College of Cardiology highlights the dangers of heat stroke, with authors stressing the association of heat stroke with multi-organ dysfunction, sometimes culminating in cardiac arrest [].

Considering the evidence presented by Eliason and colleagues, heat stroke and its complications may have been present. Related to this and to our knowledge, there exists no evidence that DMAA elevates body temperature and this has been noted in a controlled laboratory environment [5]. Another case of death associated with physical exercise was documented in , when a year-old woman died prior to completing the London Marathon in [27].

It was reported that the woman ingested a DMAA containing dietary supplement mixed in her water bottle. No additional information is available in the scientific literature pertaining to this case. Therefore, it is difficult to draw conclusions specific to the role that the supplement may have played in this situation.

Besides the observations presented above, there exists a small number of controlled laboratory studies focused on the study of DMAA, which are described below [4,5,11,].

This includes work using DMAA alone, in conjunction with caffeine and within a finished dietary supplement. From the work focused on the acute ingestion of DMAA, it is apparent that DMAA has vasoconstrictor properties, leading to a pressor effect that results in elevated blood pressure.

However, the impact of DMAA on blood pressure elevation is dose dependent, with either no change in mean blood pressure when ingested at a recommended dosage of 25 mg, a 7 mmHg mean increase when ingested at a dosage of 50 mg, or a 16 mmHg mean increase when ingested at a dosage of 75 mg [4,5].

We also noted a mean increase in SBP of 14 mmHg when a dosage of 50 mg of DMAA was ingested along with mg caffeine, an effect that was additive when considering the findings for DMAA and caffeine alone. To put the above into context, consider the increase in blood pressure with caffeine.

In the United States, adults consume on average, 4 mg per kg of body weight of caffeine per day, which equates to mg for a 70 kg lb individual [34]. With acute ingestion, caffeine elevates both systolic and diastolic blood pressure, typically in a dose dependent manner, which persists for up to three hours following ingestion.

For example, Karatzis and coworkers reported a 4 mmHg increase in both systolic and diastolic blood pressure when 80 mg of caffeine was ingested within coffee [37,38]. Robertson et al. In a review and meta-analysis, it was determined that when analyzing data from five trials, the administration of mg caffeine produced an average increase of 8.

Collectively, these data indicate that DMAA at dosages up to50 mg promotes a similar increase in mean blood pressure than does caffeine when ingested at a dosage of mg or the amount contained within approximately two cups of coffee. Aside from acute ingestion of DMAA as a stand-alone ingredient, one multi-week study was conducted to assess the safety of DMAA ingestion.

We investigated the safety profile of DMAA and caffeine, alone or in combination, when ingested for a period of 12 weeks [28]. Apart from urinary pH Pre [6.

The following studies include DMAA within the dietary supplement known as Jack3D containing a blend of DMAA, caffeine, arginine alpha-ketoglutarate, creatine monohydrate, beta alanine and schizandrol A. In one study, seven men 25±4yrs ingested two servings per day of Jack3D for two weeks [29].

On days 1 and 15, resting heart rate and blood pressure were measured and fasting blood samples were analyzed for complete blood count, comprehensive metabolic panel and lipid panel. On days 1 and 15 following blood collection, subjects ingested two servings of the supplement and heart rate and blood pressure were recorded at minutes intervals for two hours.

No significant changes were noted in any measured blood parameters, except for an increase in fasting blood glucose. In response to acute intake, no measured variable increased in a statistically significant manner. It was concluded that acute intake of Jack 3D at a dosage of two servings results in an increase in blood pressure.

Chronic intake of two servings per day of Jack 3D over a days period does not result in an elevation in resting heart rate or blood pressure.

Regarding this increase in blood glucose, it should be noted that in one other study using Jack 3D for a period of 10 weeks and in one study using DMAA alone for a period of 12 weeks, no increase in blood glucose was observed [28,31].

In fact, a slight decrease was noted in both studies. Subjects were instructed to consume servings on each workout day. The mean number of workout days per week for subjects was four and the mean number of servings of the supplement consumed on workout days was 2.

Before and after the intervention, resting blood pressure and heart rate were measured, and blood samples were collected for determination of complete blood count, metabolic panel and lipid panel.

Heart rate was noted to decrease slightly from pre-to post-intervention. No other effects of significance were noted for blood parameters. It was concluded that Jack 3D does not result in a statistically significant increase in resting heart rate or blood pressure although systolic blood pressure was increased approximately 6 mmHg with supplement use.

The supplement did not negatively impact bloodborne markers of health but may improve the blood lipid profile, as evidenced by the noted reduction in total and LDL cholesterol. Studies have also been conducted using the product OxyELITE Pro, containing a blend of DMAA, caffeine, Bauhinia purpurea, Bacopa monniera, Cirsium oligophyllum and Rauwolscine Extract.

In one such study, 4 men and 2 women No change was noted in the measured variables following 15 days of supplementation. In response to acute intake, heart rate and diastolic blood pressure were increased approximately 6 bpm and 6 mmHg, respectively.

Systolic blood pressure was increased approximately 15 mmHg with acute treatment of two capsules of OxyELITE Pro. Using an acute study design, twelve subjects men Breath samples were collected immediately before ingestion and at 30, 60, 90 and minutes post ingestion, for a measure of energy expenditure.

Heart rate and blood pressure were recorded at all times. Acute ingestion of two capsules of the supplement increased energy expenditure, heart rate and blood pressure above pre-ingestion values; values were greater than observed for placebo.

Specifically, heart rate was stable for men ~ 60 bpm at all measurement times but increased 7 bpm for women. Systolic blood pressure increased approximately 20 mmHg for men and 12 mmHg for women, while diastolic blood pressure increased approximately mmHg for both men and women.

The use of a lower dosage may attenuate this response. Subjects were provided the option to use either 1 or 2 capsules per day.

This was done to duplicate the conditions in which individuals would use this dietary supplement in a non-laboratory setting. For both conditions, capsules were taken with water on an empty stomach in the early morning, and if taking a second dosage, this was to be taken during the early to mid afternoon.

Body weight, body composition, complete blood count, comprehensive metabolic panel, resting heart rate and blood pressure were measured pre-andpost-intervention.

When comparing pre-and post-intervention values for the supplement, significant decreases were noted in body weight and body fat percentage, while an increase was noted for resting heart rate approximately 6 bpm.

Blood pressure was increased slightly with the supplement approximately 3 mmHg but not with placebo. Of the 16 subjects assigned to OxyELITE Pro, 11 ingested two capsules per day and five ingested only one capsule per day.

These five subjects indicated that the ingestion of two capsules was associated with increased feelings of jitters and sleeplessness. None of the remaining 11 subjects assigned to the supplement noted any adverse effects of treatment.

Because of the chemical composition of DMAA and its similarity to other compounds, it has been suggested that the user may become dependent to this agent [41,42].

Dolan and Gatch, using a rodent model, investigated the abuse liability profile of DMAA compared to cocaine and methamphetamine [43]. Results indicated that DMAA produced reward-like effects and may produce subjective effects like that of abused psycho stimulants.

Because this study was conducted using mice, with dosing delivered via intraperitoneal injection at amounts that may not be representative of what most humans would ingest 0. Regardless, this outcome illustrates the potential to abuse and misuse DMAA, something that has been noted anecdotally by those claiming to use this ingredient.

Clearly, more human studies would be needed to more fully understand the potential abuse liability of DMAA. Some individuals have suggested that DMAA ingestion results in elevated body temperature and impaired thermoregulation. We are unaware of evidence that supports this assertion. Our work indicates that body temperature is maintained within one degree Fahrenheit during a hours post ingestion period after men received a single dosage of 25 mg of DMAA [5].

In support of the above findings, other well-recognized stimulants such as caffeine and ephedrine have been noted to have minimal to no impact on body temperature, even during exercise heat stress [44,45]. For example, one study conducted by investigators at the Army Research Institute of Environmental Medicine used a sample of 10 men who exercised in the heat °F [44].

In , there have been at least 30 cases since the middle of the year. The multiple uses of methylhexanamine confuse the issue when an athlete tests positive for it.

Of course, there is the possibility that the athletes were deliberately taking it to gain some advantage, and this being sport, it would be naive not to recognize that this happens too often.

And quite frankly, if a professional athlete is looking for an advantage, there are better ways to do it. When the two South African rugby players tested positive after a Test match in Wales in November, the first reaction by many in the media was that they had mistakenly used medicine for a cold.

However, this is unlikely in modern day professional sport, for the simple reason that everyone is so sensitive to the possibility of it happening — there are some very high profile, very damaging cases of this very mistake being made, and so most professional sports teams will be particularly careful about giving out cold and flu medicine to athletes.

When an athlete presents to the doctor complaining of any symptoms, usually the very first check is to make sure that the athlete does not dope — teams now have lists of what they can and cannot take, and most travel with medicines that have already been cleared.

And certainly, the Springbok rugby team has a very experienced, very good doctor who would not make this error. She then tested positive for pseudo-ephedrine, an ingredient of Nurofen, which was given to her by a team physician, and was stripped of her gold medal.

The case went all the way to the Court of Arbitration for Sport CAS , where it was ruled that Raducan should be exonerated of any wrongdoing, but that the medal should still be taken away. The physician meanwhile, was banned for two Olympic cycles for what really was a catastrophic error for a young athlete.

The next option is that the players took it in a recreational drug. Tests done out of competition, perhaps, but not hours after playing. So we arrive at the third possibility — contaminated supplements. Supplements are now indispensable to elite athletes, whether they are for weight loss, muscle gain, recovery, performance, I would be surprised if any elite athletes do not use some form of supplements.

Now, in the cases of methylhexanamine, the supplement argument has come up repeatedly. The athlete is of course responsible for making sure, and had he done full and detailed homework, he may have discovered that he was in fact taking a banned substance.

I went to a local pharmacy in the aftermath of the SA Rugby cases and within 10 minutes, had found three substances that actually listed methylhexanamine as an ingredient.

Methylhexanamine in athletic performance -

I went to a local pharmacy in the aftermath of the SA Rugby cases and within 10 minutes, had found three substances that actually listed methylhexanamine as an ingredient. In that case, the athlete deserves the full two-year ban, because ignorance is not a defence in doping cases, and so Taelman is a little lucky.

However, even this is subtly different from contamination, but it brings me back to the point above — an athlete has NO WAY OF KNOWING that a supplement is guaranteed to be safe, unless they test that batch for every possible banned substance.

In my opinion the case is still pending , this is the likely cause of the positive tests results of the SA rugby players, and is likely to also be the case in many other methylhexanamine positives.

This happened recently in South Africa, to a schoolboy rugby player, and sets a precedent for the Springbok players, who are thus likely to get sanctioned for less than the two years normally given for a doping violation.

A final word then is whether the banned list is too broad, too large? Should this substance, and many others, even be on the list? This has come up on this site before, when we interviewed Prof Bengt Kayser, who was of the opinion that doping control would be more effective if the number of banned substances was cut right down , leaving only those that have a profound effect on performance and are unsafe.

Given the probably very marginal effect of a substance like methylhexanamine it has never been fully tested for sport , and the potentially high risk of inadvertent use with career ending implications for the player , this argument may well have merit.

In the aftermath of the SA Rugby cases, I was interviewed by a journalist who raised this very question: Where do we draw the line with regards to how we define doping? Andreea Raducan has only one gold medal, not two, thanks to a drug that likely did nothing for her performance, and is not even banned anymore.

Skip to primary navigation Skip to main content. The problem with supplements is two-fold: There is very little testing to establish the efficacy or effectiveness of supplements.

Creatine is a notable exception, and of course, some supplements provide macro-nutrients proteins and carbs that are known to aid recovery and performance. The safety is never established. This has two components. First, there is no guarantee that the dizzying array of ingredients is safe to begin with — many are herbal, thrown in for effect and on a very tenuous link, and many are only a chemical reaction away from being risky.

Then second, there is a risk of contamination. In other words, if a squad of 30 footballers all take the same supplement, 7 or 8 of them may be taking a banned substance inadvertently. These substances are not listed on the label, but they find their way into the bottle, as a result of what is non-existent control over the manufacture process of supplements.

The sources of this contamination include the sourcing of the raw materials, the machinery and the packaging plants. The end result is that there is no such thing as a guaranteed safe supplement. Food for thought…thanks to our drug of the year, methylhexanamine!

This is a guide written by SA Rugby and the dietician at the Sports Science Institute of South Africa, and it outlines the suggested approach to supplements.

The cricketer Shane Warne tested positive for the diuretics hydrochlorothiazide and amiloride before the World Cup. He said he had no idea the substances were present in slimming pills that were given to him by his mother that were designed to reduce fluid retention but he still received a one-year ban.

In October, UK Anti-Doping launched a drive to warn athletes of the dangers of taking supplements. The presence of contaminated substances or misleading packaging would be no defence, it said.

The Hamilton Academical footballer Simon Mensing recently served a month's ban after testing positive for methylhexaneamine. Mensing, who was taking supplements to lose weight, had checked with two retailers and his club's fitness coach that the wording on the front of the packaging — "no banned substances" — was correct.

In its judgment, UK Anti-Doping gave credit both for the fact that Mensing had sought advice and that he had no intention of seeking to enhance his performance.

If Touré is not considered to have taken reasonable steps, he could face a far longer suspension. If the tablets contained diuretics, ignorance would be no defence.

Dietary supplements can contain banned substances as active ingredients, in which case they will usually but not always be listed on the label. But supplements can contain ingredients listed by a different name from that on the Wada list, and batches can be contaminated. While the Football Association, which will handle Touré's case according to Ukad guidelines, will want to progress quickly, experience suggests any hearing may not take place for months.

Touré will be offered the chance to have a B sample tested. This will have been collected at the same time as the original. If the B sample confirms the result he will be asked to explain himself in writing and before a full hearing in front of a panel.

The panel will then deliberate and hand down a punishment. Any punishment can be appealed, all the way to the Court of Arbitration for Sport in Lausanne.
