TL;DR — Even a perfectly sourced peptide degrades if handled wrong. Store lyophilized vials cold, reconstitute with bacteriostatic water added gently, refrigerate the solution, and use sterile technique throughout.

Even a perfectly sourced peptide degrades if handled wrong. Storage and reconstitution are where research integrity is quietly won or lost.
Storing lyophilized (powder) vials
- Long-term: −20°C freezer (stable for years)
- Short-term: 2–8°C refrigerator (up to 6–12 months)
- Avoid: room temperature, heat, direct light, moisture
Reconstitution
Peptides are reconstituted with bacteriostatic water (0.9% benzyl alcohol), which resists microbial growth. Add the water slowly down the side of the vial — never spray directly onto the powder — and swirl gently rather than shaking.
Storing reconstituted solution
- Refrigerate at 2–8°C
- Use within roughly 14–28 days
- Do not freeze a reconstituted solution
Sterile handling
Use sterile technique: alcohol-swab the stopper, use clean supplies (.22µm filters, sterile vials), and label every vial with compound, concentration, and date. Stability varies — BPC-157 and TB-500 are relatively robust; some nootropic peptides are more temperature-sensitive.
