| Peptide | Category | Lyophilized (powder) | Reconstituted (mixed) | Evidence |
|---|---|---|---|---|
| AOD-9604 | Weight loss/Fat metabolism | Refrigerate 2-8C or freeze -20C for long-term. Standard peptide storage. | Refrigerate at 2-8C. Use within 4-6 weeks. Do not freeze. | Early research |
| BPC-157 | Recovery | Room temperature is fine for shipping, but refrigerate (2-8C) for long-term storage. Stable for 12+ months sealed. | Refrigerate immediately. Use within 4-6 weeks. Never freeze after reconstitution. | Emerging evidence |
| CJC-1295 (no DAC) | Muscle growth | Refrigerate at 2-8C. Keep away from light. Stable for 12+ months sealed. | Refrigerate. Use within 3-4 weeks. CJC is slightly more fragile than ipamorelin. | Emerging evidence |

| GHK-Cu | Beauty | Refrigerate at 2-8C. Keep away from light. The powder is blue-tinted. | Refrigerate. Use within 3-4 weeks. The blue color should remain consistent — if it changes, discard. | Emerging evidence |
| Ipamorelin | Muscle growth | Refrigerate at 2-8C. Stable for 12+ months sealed. | Refrigerate. Use within 3-4 weeks. | Emerging evidence |
| KPV | Recovery/Anti-inflammatory | Refrigerate 2-8C or freeze -20C for long-term. Stable as dry powder for 12+ months. | Refrigerate at 2-8C. Use within 4 weeks. Do not freeze. | Early research |
| MOTS-c | Longevity | Refrigerate at 2-8C. MOTS-c is relatively stable but keep it cold. | Refrigerate. Use within 3-4 weeks. | Emerging evidence |
| Melanotan II | Beauty | Refrigerate at 2-8C. Protect from light. | Refrigerate. Use within 4-6 weeks. Protect from light. | Early research |
| NAD+ | Longevity/Energy | Refrigerate 2-8C. Freeze for long-term storage. Light-sensitive — keep in original vial. | Refrigerate at 2-8C. Use within 2-4 weeks depending on formulation. | Early research |
| PT-141 | Sexual health | Refrigerate at 2-8C. Stable for 12+ months sealed. | Refrigerate. Use within 4-6 weeks. | Strong evidence |
| Retatrutide | Weight loss | Refrigerate at 2-8C. Stable for 6+ months sealed. | Refrigerate. Use within 28 days. | Emerging evidence |
| Selank | Cognitive/Anxiety | Refrigerate at 2-8C for short-term. Freezer (-20C) for long-term. Stable 2+ years frozen. | Refrigerate immediately. Use within 14-21 days. Never freeze reconstituted solution. | Emerging evidence |
| Semaglutide | Weight loss | Refrigerate at 2-8C. Compounded lyophilized vials are stable for 6+ months sealed. | Refrigerate immediately. Use within 28 days. Never freeze. | Strong evidence |
| Semax | Cognitive/Neuroprotection | Refrigerate at 2-8C or freeze at -20C for long-term. Stable 2+ years frozen. | Refrigerate and use within 14-21 days. Do not freeze. | Emerging evidence |
| SS-31 (Elamipretide) | Longevity/Mitochondrial | Freeze at -20C for long-term storage. Stable for 2+ years. Refrigerate for short-term. | Refrigerate at 2-8C. Use within 4 weeks. Do not freeze. | Strong evidence |
