- Bacteriostatic Water (2mL per 5mg vial)
- 2.5mg/mL (1.76mM)
- 28 days at 2–8°C
- In vivo subcutaneous injection, multi-dose protocols
- Requires refrigeration; degradation begins immediately
- Gold standard for animal studies. Benzyl alcohol prevents contamination in multi-dose vials
- Bacteriostatic Water (1mL per 5mg vial)
- 5mg/mL (3.52mM)
- Higher-dose protocols, reduced injection volume
- Higher concentration increases precipitation risk if pH drifts
- Use only when injection volume must be minimised (e.g., neonatal models)
- PBS (2mL per 5mg vial)
- 48 hours at 2–8°C, or single-use aliquots at −20°C for 90 days
- In vitro cell culture, serum-free media applications
- No bacteriostatic agent. Microbial growth risk in multi-dose vials
- Required for cell culture work; impractical for multi-week animal studies without aliquoting
- Sterile Water (2mL per 5mg vial)
- 24 hours at 2–8°C
- Single-use immediate injection
- Hypotonic solution can cause hemolysis at injection site; no contamination barrier
- Avoid unless institutional protocol prohibits benzyl alcohol (rare)
- BPC-157 research strength considerations demand choosing reconstitution solvent and concentration based on study duration, injection frequency, and assay type. Bacteriostatic water at 2.5mg/mL is the most versatile standard. It balances stability, ease of dosing calculation, and contamination resistance across multi-week protocols.
