- Growth Hormone Secretagogues (Ipamorelin, GHRP-2, GHRP-6)
- Moderate—stable tertiary structure
- 28 days with BAC water, 48 hours with sterile water
- Temperature excursion during storage
- Highly forgiving if cold chain maintained; benzyl alcohol essential for multi-dose protocols
- Modified GH Analogs (CJC 1295, Sermorelin, Tesamorelin)
- High—extended sequences prone to aggregation
- 21–28 days with BAC water, avoid sterile water
- Shaking-induced denaturation, incorrect reconstitution concentration
- Requires precise protocol adherence; aggregation above 3 mg/mL common
- Thymic Peptides (Thymosin Alpha 1, Thymalin)
- Moderate—disulfide bonds stabilize structure
- 28 days with BAC water
- Oxidative degradation if air exposure during draws
- Benzyl alcohol's antioxidant effect critical; minimize air headspace
- Healing Peptides (BPC 157, TB 500)
- Low—robust sequences, high thermal stability
- 28 days with BAC water, 72 hours with sterile water
- Contamination from non-sterile reconstitution technique
- Least sensitive category but still requires BAC water for multi-dose use
- GLP-1 Receptor Agonists (Tirzepatide, Semaglutide, Retatrutide)
- Very High—long-chain structure, multiple modification sites
- 14–21 days with BAC water, unusable with sterile water
- Aggregation at >2 mg/mL, thermal shock during reconstitution
- Strictest cold chain requirement; refrigerate BAC water before use
- Nootropic Peptides (Semax, Selank, Dihexa)
- Moderate—short sequences but unprotected termini
- 21 days with BAC water
- Enzymatic degradation if bacterial contamination occurs
- Bacteriostatic water non-negotiable; peptidase activity from bacteria destroys compound
- BAC water is the universal solvent for research peptides because it addresses the two primary failure modes simultaneously: bacterial contamination (which introduces peptidases that cleave peptide bonds) and oxidative degradation (which benzyl alcohol mitigates). The stability duration differences reflect intrinsic peptide chemistry, not BAC water formulation.
