⸻
💪 2. IGF-1 LR3
A peptide studied for its role in muscle cell growth.
Research focus:
• Muscle cell development
• Nutrient partitioning
⸻
💪 3. MK-677 (Ibutamoren)
A growth hormone secretagogue studied in performance research.
Research focus:
• Growth hormone increase
• Recovery enhancement
• Sleep quality
⸻
💪 4. Tesamorelin
A peptide studied for its effects on body composition.
Research focus:
• Fat reduction
• Lean muscle preservation
⸻
💪 5. BPC-157
While not directly a muscle builder, it is frequently studied for recovery.
Research focus:
• Injury recovery
• Tendon and ligament support
📊 Comparison Table
| Peptide | Main Focus | Best For |
| CJC-1295 + Ipamorelin | GH release | Lean muscle |
| IGF-1 LR3 | Muscle growth | Size |
| MK-677 | GH + recovery | Overall growth |
| Tesamorelin | Fat + muscle | Body recomposition |
