10 PEDs Banned by CrossFit and How They Affect the Human Body

Fifty-two-year-old Josée Sarda of Canada East, who placed first in the Masters Women 50-54 Division, tested positive for selective androgen receptor modulators (SARMs), ostarine and testolone.

SARM stands for selective androgen receptor modulator, and it’s a type of drug that’s chemically similar to anabolic steroids. SARMs are drugs that deliver some of the benefits of anabolic steroids with fewer of the short-term side effects.

Research clearly shows that they suppress natural testosterone production and negatively impact the endocrine system, and there’s evidence that they can increase the risk of cancer, too. Several large trials on the SARM cardarine had to be cancelled because it was causing cancerous growths in the intestines of mice.


Ostarine is a Selective Androgen Receptor Modulator (SARM). It was developed by a pharmaceutical company known as GTX to help people to fight against muscle-wasting conditions. It achieves the end result by binding androgen receptors in the same manner as prohormones or anabolic steroids.
