What are SARMs?
SARMs (Selective Androgen Receptor Modulators) are compounds designed to selectively interact with androgen receptors in the body. Unlike traditional anabolic steroids, SARMs aim to offer specific benefits such as muscle growth and fat loss, but with less impact on other tissues like the liver, prostate, or skin.
How do they work?
SARMs work by selectively binding to androgen receptors in muscles and bones, activating anabolic pathways without significantly affecting other organs. This theoretical selectivity differentiates them from steroids, which act more generally throughout the body.
Main Types of SARMs
| SARM | Primary Use | Notes |
|---|---|---|
| Ostarine (MK-2866) | Muscle preservation, body recomposition | One of the most studied and popular |
| Ligandrol (LGD-4033) | Muscle mass gain | Higher anabolic potency |
| RAD-140 (Testolone) | Strength and muscle mass | Designed as a testosterone alternative |
| Andarine (S4) | Muscle definition | Noticeable visual effects |
| Cardarine (GW-501516) | Endurance and fat burning | Technically not a SARM, but a PPARδ agonist |
| Ibutamoren (MK-677) | Growth hormone release | Not a SARM, it’s a GH secretagogue |
Potential Benefits
- Increase in lean muscle mass
- Improved bone density
- Faster recovery
- Reduction in body fat
- Less hormonal suppression than steroids (varies by compound)
Current Scientific Perspective
Research on SARMs continues, with some compounds showing promise for:
- Treatment of sarcopenia (age-related muscle loss)
- Osteoporosis
- Muscle wasting in chronic diseases
