Mechanisms
Selective Androgen Receptor Modulator (SARM): binds to androgen receptors in target tissues. The overall physiological impact depends on dose, tissue selectivity, and individual biology.
Detailed mechanism
Selective Androgen Receptor Modulator (SARM) that binds to androgen receptors in tissues including muscle and prostate. The degree of suppression of endogenous hormones is a key safety consideration.
Safety
Side effects
- Possible suppression of natural testosterone
- Hair loss in those genetically predisposed
- Potential lipid or liver enzyme changes
- Possible libido changes and longer recovery for some
Reported benefits
- Potential androgen-receptor signaling changes in research contexts
- Oral administration
Safety profile
Limited human safety data. Potential risks include hormone suppression and organ effects; medical supervision is recommended for any clinical context.
Clinical trials
Research studies; not broadly established as an approved medication for performance purposes.
