- Multi-dose viability post-reconstitution
- 28 days refrigerated
- 48–72 hours maximum
- 7–10 days if uncontaminated
- BAC water is the only option for standard multi-dose protocols. Sterile water requires single-use reconstitution immediately before each injection
- Bacterial contamination resistance
- Benzyl alcohol inhibits microbial growth
- None. Bacterial proliferation begins within hours of first puncture
- Mild osmotic pressure may slow growth but does not prevent it
- Only BAC water actively prevents contamination between draws
- Peptide stability (% potency at 28 days)
- 92–97% under refrigeration
- Not applicable. Unsafe for multi-dose use beyond 72 hours
- 78–85% if contamination avoided
- BAC water maintains near-original potency; saline shows measurable degradation
- Injection site tolerance
- 0.9% benzyl alcohol may cause mild stinging in sensitive individuals
- No irritation
- BAC water's preservative can cause transient discomfort. Saline is better tolerated but lacks preservation
- Cost per 30mL vial
- $8–$15 pharmaceutical-grade
- $3–$6
- $4–$8
- The $5–$10 premium for BAC water is negligible compared to peptide replacement costs from contamination
- Regulatory classification
- USP-grade pharmaceutical excipient
- USP sterile water for injection
- USP normal saline
- All three are pharmacy-grade when sourced correctly. BAC water is specifically formulated for multi-dose reconstitution
