Peptide Storage Guide: Maximize Shelf Life

Proper storage is essential to maintain peptide potency. Degraded peptides lose effectiveness and can produce unreliable results.

Lyophilized (Powder) Storage

• Room temperature: Stable for months to years
• Refrigerated: Even longer stability
• Keep away from direct light and moisture
• Desiccant packets help in humid environments

Reconstituted (Liquid) Storage

• Always refrigerate at 2-8C (standard fridge)
• Use within 28-30 days for optimal potency
• Never freeze reconstituted peptides (ice crystals damage structure)
• Bacteriostatic water extends usable life vs sterile water

Signs of Degradation

• Cloudy solution (should be clear)
• Particles or precipitate visible
• Color change
• Reduced effectiveness over time
