Seeing conflicting information across sources on reconstitution and storage. Wanting to compile a community-verified reference.
What I know so far:
- Bacteriostatic water (0.9% benzyl alcohol) prevents microbial growth, extending reconstituted peptide life to ~4 weeks refrigerated
- Sterile water without preservative: use within 3-5 days
- Most peptides stable 6-12 months lyophilized at -20°C
- Amber vials matter - light degrades certain peptides faster
Open questions:
1. How many freeze-thaw cycles before meaningful potency loss?
2. Does vacuum seal matter for lyophilized storage?
3. BPC-157 - particularly light-sensitive post-reconstitution?
4. TB-500 stability at room temperature for shorter periods?
Anyone with chemistry or compounding backgrounds who can speak to actual stability data would be incredibly valuable.
