- Pre-reconstitution storage
- −20°C, 24–36 months
- −20°C, 18–24 months
- Room temperature, 36 months
- Melanocortins require strictest cold-chain. Photosensitive and moisture-sensitive
- Reconstitution required
- Yes. Bacteriostatic water
- No. Oral compound
- Lyophilized peptides demand sterile technique; oral compounds eliminate handling risk
- Post-reconstitution stability
- 28 days at 2–8°C
- N/A
- All injectable peptides share 28-day window. Dictated by bacteriostatic water, not peptide
- Freeze-thaw tolerance
- Zero. Each cycle = 15–25% loss
- Low. Max 2 cycles
- Reconstituted peptides cannot tolerate freezing under any circumstance
- Light sensitivity
- High (wrap in foil)
- Moderate
- None
- Melanocortins degrade via photo-oxidation. Most significant handling difference
