Selective Androgen Receptor Modulators (SARMs) are a class of therapeutic compounds that have similar properties to steroids, but with reduced androgenic properties. There is a misconception floating around that SARMS are completely anabolic substances and carry no androgenic properties. That is not technically true as SARMS does possess some androgenic properties and has a high binding affinity for the androgen receptor. However, the androgenic properties of SARMS are so minimal that they are pretty much negligible. Even the most androgenic SARM has less than one-tenth of the androgenic properties of testosterone.
The main difference between SARMS and steroids is that SARMS act in a very targeted way and are very selective in their mechanisms of action. SARMS have a special affinity for certain tissues like muscle and bone, but not for other tissues like the prostate, liver, and brain. They also don’t convert into unwanted molecules that cause side effects, like DHT and estrogen. This makes side effects associated with steroid usage like gynecomastia, water retention, hair loss, etc. impossible with SARM usage.
Most SARMs will only minimally suppress natural testosterone production and hypothalamic-pituitary-testicular axis (HPTA) function. The only exceptions are the SARMS YK-11 and S-23.
Although commonly referred and sold as SARMS, gw-501516, sr-9009 and Mk-677 are actually not SARMS at all. Gw-501516 is a PPAR agonist. Sr-9009 is a Rev-Erba agonist and Mk-677 is a human growth hormone secretagogue. All three of these compounds possess no anabolic or androgenic activity and will not affect natural testosterone production or the Hypothalamicpituitary-testicular axis (HPTA) in any way. This makes them great to use in post cycle therapy or as bridges between the steroid cycle.
Things you need to know:
- SARMS are similar to steroids but act in a very targeted way that causes side effects like gynecomastia, water retention and hair loss impossible.
- With the exception of YK-11 and S-23, SARMS are only minimally suppressive of natural testosterone production and HPTA function
- Although sold as SARMS, gw-501516, sr-9009 and Mk-677 are actually not SARMS at all.
