“SARMs” have emerged as a new class of appearance- and performance-enhancing substances. Before you consider using one, learn the facts here.
What are SARMs?
SARMs—short for “selective androgen receptor modulators”—are synthetic drugs designed to have effects similar to those of testosterone. SARMs are still in the research and testing stages for various medical conditions but have not been approved yet for any other use. Despite that, SARMs are readily available online and often marketed to bodybuilders as “legal steroids” or “steroid alternatives” or for “research only.”
Are SARMs safe or legal?
Although SARMs sometimes are sold in products marketed as dietary supplements, FDA has stated they are not dietary supplements and are unapproved by FDA for human use. The World Anti-Doping Agency (WADA) and National Collegiate Athletic Association (NCAA) prohibit SARMS for use in sport.
If you have purchased or considered using SARMs, including dietary supplement products labeled as containing a SARM (that is, with one or more SARMs on the Supplement Facts panel) or products marketed for research purposes only (and not for human consumption), think again! We strongly advise against using such products, because they pose significant health and readiness risks. Ostarine and similar SARMs also might cause positive results if you are tested for steroids. Importantly, use of SARMs might interfere with the natural release of your own testosterone.
What ingredients should you look out for?
Some of the ingredient names to watch out for on dietary supplement product labels and websites include (but are not limited to) the following:
- Andarine (S4)
- Enobosarm (Ostarine, MK-2866)
- Ligandrol (LGD-4033)
- RAD140 (Testolone)
Watch out too for other experimental drugs—such as Cardarine/GW-501516, Ibutamoren/MK-677, and YK11—that sometimes are marketed as SARMs; they aren’t, but they also are illegal for any use other than research.
