Performance Compounds
Peptides vs SARMs
Two popular categories of research compounds for physique enhancement. Different mechanisms, different effects, different risk profiles.
Peptides
Amino acid chains that signal hormone release. Work indirectly through GH, healing factors, etc. More subtle, better for recovery and healing.
SARMs
Selective Androgen Receptor Modulators. Bind directly to androgen receptors like steroids, but more tissue-selective. Stronger for muscle building.
Head-to-Head Comparison
| Factor | Peptides | SARMs |
|---|---|---|
| Muscle Building | Moderate/indirect | Strong/direct |
| Fat Loss | Good (GH peptides) | Moderate |
| Recovery/Healing | Excellent | Minimal |
| Hormonal Suppression | None to minimal | Yes (varies) |
| PCT Needed | Usually no | Often yes |
| Liver Toxicity | Very low | Low-moderate (oral) |
Popular Peptides
- BPC-157: Healing, gut health
- TB-500: Tissue repair
- CJC-1295/Ipamorelin: GH release
- MK-677: GH secretagogue
Popular SARMs
- RAD-140: Strength, muscle
- LGD-4033: Mass building
- Ostarine (MK-2866): Mild, versatile
- Cardarine (GW-501516): Endurance*
*Technically not a SARM
Legal & Health Warning
Both peptides and SARMs are sold as "research chemicals" - not for human consumption. SARMs are on WADA banned list and face increasing regulation. Neither is FDA-approved for performance enhancement.
