Sterile water: 5-7 day shelf life maximum Why sterile water has shorter shelf life: No preservatives (no benzyl alcohol) Bacteria can multiply freely if contaminated Higher contamination risk Designed for single-use vials Should only use for immediate injection (pharma standard) Shelf life with sterile water: Days 1-3: 95-100% potency, low contamination risk Days 4-5: 90-95% potency, moderate risk Days 6-7: 85-90% potency, higher risk Days 8+: Not recommended, high contamination risk When to use sterile water: Single-dose vials (use entire vial immediately) Don't have bacteriostatic water available Allergic to benzyl alcohol (rare) Pharmaceutical peptides intended for single use Why bacteriostatic is better: 4x longer shelf life (28 days vs 7 days) Much safer for multi-dose vials Standard in research peptide community Allows reconstituting full vial, using over weeks Converting to bacteriostatic: If you have sterile water, get bacteriostatic water Reconstitute with bacteriostatic for standard shelf life Small investment for much better results Never freeze reconstituted peptides Why freezing liquid peptides is bad: Ice crystals form during freezing Ice crystals physically damage peptide structure Peptides denature (unfold) during freeze Aggregation occurs when thawed Significant potency loss (30-50%+) Can make peptide completely inactive The myth: Some people think freezing = preserving True for lyophilized powder (no water) False for reconstituted liquid (water present) Water freezing is the problem If you accidentally froze reconstituted: Likely 50-70% potency loss May still have some effect Visual inspection: Cloudiness or particles = bad If clear after thawing, might work partially Better to discard and reconstitute fresh Proper long-term storage: Keep peptides as lyophilized powder frozen Reconstitute only what you'll use in 30 days Don't reconstitute entire supply at once Plan doses based on 30-day window Use our free peptide calculator at SeekPeptides to calculate how much to reconstitute for your protocol duration
