Ostarine – A Banned Substance in Sport and Illegal Dietary Supplement Ingredient

About Ostarine

The drug ostarine, also known as MK-2866, GTx-024 or enobosarm, is considered a SARM, or Selective Androgen Receptor Modulator. It was developed in the mid 2000s to help combat bone and muscle wasting in people suffering from a range of debilitating diseases and aging but is still being clinically researched and is not yet an approved drug. It is designed to activate the androgen receptor in a similar fashion to anabolic steroids. Because it produces strength gains similar to those of anabolic steroids without unpopular androgenic side effects, the drug has become a prevalent steroid alternative for bodybuilders and athletes.

About SARMS

SARMS is a broad term referring to various substances that bind to androgen receptors and activate in certain tissues such as muscle and bone. Though some early SARMS were steroidal in origin, the term SARMS commonly refers to a new and distinct category of drugs—Non-steroidal Selective Androgen Receptor Modulators—which is part of their appeal. Tissue selectivity is a key component of how SARMS are seen to work, bolstering gains in certain areas with less damage to other body parts such as the liver or prostate. SARMS continue to be evaluated for their potential to serve as effective medicines in combating muscle wasting conditions and other disorders. The safety and efficacy of SARMS, however, has yet to be established, and no SARM has been approved as a drug for human use.

Status of Ostarine

A Banned Substance in Sport:
Ostarine was added to WADA’s Prohibited List in 2008 and remains banned today, along with other SARMS, by all major sporting organizations. As of 2017, dozens of athletes, from female triathletes to male American football players, have tested positive for the substance and suffered suspensions as a result. As a category, SARMS has become one of the more prevalent anabolic agents reported in sport drug testing.

Illegal Dietary Supplement Ingredient:
Unfortunately, ostarine and other SARMS have become popularized as active ingredients in dietary supplements by unscrupulous companies that tout the drugs as being “completely legal.” This is simply not true, as no SARM is considered a legal dietary supplement ingredient nor has any been approved for human consumption. Other supplement companies may include the ingredient in its products under a different name or without listing it.

In the United States, ostarine and other SARMS can only be used for research and medical-testing purposes. Often the unscrupulous brands attempt to hide behind the suggestion that their products are only for research use, but that excuse is voided as soon as a product is capsulated and dosed for human consumption. Do not be fooled by this ruse; SARMS are illegal dietary supplement ingredients and their inclusion in a product would be considered sale of an unapproved drug by the FDA (U.S. Food & Drug Administration) and most of its global equivalents.

In 2014, the FDA warned a supplement company that one of their products contained ostarine and explained that as a substance being researched as a drug, it was not legal to sell. That remains the case in 2017, although there have only been one or two warning letters sent since addressing the illegal sale of ostarine or other SARMS. It should be noted that one of the most significant efforts to address the illegal sale of SARMS in the dietary supplement industry was martialed by a dietary supplement brand, Nutrition Distribution. The dearth of regulatory action necessary to effectively address the illegal sale of ostarine and SARMS as dietary supplements has sadly allowed them to proliferate.

As a result, ostarine and other SARMS have invaded the dietary supplement industry creating the very real possibility of cross contamination occurring in the manufacturing environment, or in raw material sourcing. Because of the significant money available to manufacturing facilities who are willing to break the law and make SARMS into dietary supplement products, some end up manufacturing SARMS in otherwise legitimate facilities clandestinely, often after hours, exposing other legitimate products to contamination. A circumstance like this resulted in an athlete testing positive who had used a benign supplement that was made in a facility that also produced SARMS. This magnifies the importance of certification programs like BSCG’s that test supplement products to demonstrate they are free of ostarine, SARMS and other doping agents.

Health Risks of Ostarine

Though ostarine appears to present fewer serious and androgenic side effects than anabolic steroids, the substance still can negatively affect one’s health. Headaches, acne and skin problems, hair loss and reduced testosterone levels have all been noted. Studies of other SARMS have revealed vision problems and, alarmingly, the growth of cancers. The extent of short-term and long-term effects are still being investigated and remain unknown.
