- Storage Temperature
- Room temp (15–25°C) acceptable
- 2–8°C refrigeration required
- −20°C freezer required
- Temperature excursions above 8°C denature reconstituted peptides irreversibly. Neither appearance nor potency testing at home can detect this
- Shelf Life
- 24–36 months sealed
- 28 days after first puncture
- 12–36 months at −20°C
- 28 days maximum at 2–8°C
- The 28-day clock for both opened BAC water and reconstituted peptides is a hard limit. Benzyl alcohol efficacy degrades past this point
- Contamination Risk
- Sterile until opened
- Increases with each draw
- Minimal (dry powder)
- High if sterile technique lapses
- Every needle puncture is a contamination opportunity. Non-sterile draws compromise the entire vial, not just the drawn dose
- Freeze-Thaw Tolerance
- Not applicable
- Do not freeze
- Tolerates multiple cycles
- Single freeze-thaw destroys peptide
- Freezing reconstituted peptides causes ice crystal formation that shears peptide bonds. The solution may look clear after thawing but potency is compromised
- Visibility of Degradation
- Clear solution remains clear
- Cloudiness indicates contamination
- Powder colour may yellow with age
- Aggregation appears as visible particles
- Clear appearance does not guarantee potency. Hydrolysis and oxidation occur at the molecular level without visible change
