SARMs (Selective Androgen Receptor Modulators) are research compounds designed to provide anabolic benefits with reduced androgenic side effects compared to traditional anabolic steroids.
How SARMs Work
SARMs selectively bind to androgen receptors in muscle and bone tissue, triggering anabolic effects while minimizing activity in other tissues like prostate and skin.
Popular SARMs
- Ostarine (MK-2866): Mild, good for cutting and beginners
- LGD-4033: Strong, excellent for bulking
- RAD-140: Potent, comparable to testosterone
- S-23: Strongest, extreme cutting
SARMs vs Steroids
SARMs offer targeted muscle effects without many steroid side effects, but they still cause suppression and require PCT.
Legal Status
SARMs are legal to buy for research purposes but banned in competitive sports and not FDA-approved for human use.
