General Temperature Guidelines #
Lyophilized (Unmixed) Peptides #
- Typically stable at room temperature (20–25°C) for short periods
- Best stored at -20°C or lower for long-term storage
- Maximum temperature: Up to 40°C for very short periods — prolonged exposure must be avoided
Peptides in Solution (Mixed) #
- Most peptides should be kept refrigerated (4°C)
- Generally stable for a few weeks at this temperature
- Maximum temperature: Do not expose to temperatures above 25°C for any extended period
- Short-term exposure to room temperature (up to 30°C) is usually tolerable but avoid prolonged exposure
Sensitive Peptides (Extra Caution Required) #
Peptides containing methionine, cysteine, tryptophan, or asparagine are more sensitive to oxidation and heat:
| Peptide | Sensitivity | Storage Recommendation |
|---|---|---|
| Oxytocin | Degrades above 25°C | Always at 4°C in solution |
| BPC-157 | Relatively stable | 4°C preferred for best results |
| Thymosin Alpha-1 | High temperature sensitivity | -20°C, keep ≤4°C in solution |
| Epithalon | Moderate sensitivity | -20°C recommended long-term |
Summary Guidelines #
- Lyophilized: Safe up to 40°C briefly, keep at -20°C for longevity
- Mixed: Never above 25°C for extended periods, refrigerate at 4°C
- Protect from air, light, and repeated temperature cycling
