Peptide Storage Guide — How to Store Peptides Safely
Proper storage is critical to maintaining peptide potency. Learn the best practices for storing lyophilized and reconstituted peptides, including temperature requirements, light protection, and shelf life expectations.
This guide covers storage for research peptides including BPC-157, TB-500, and other common compounds.
Key Storage Rules
Lyophilized powder: Store at -20°C (freezer) long-term, or 2–8°C (refrigerator) for up to 3–6 months
Reconstituted solution: Refrigerate at 2–8°C. Use within 30–60 days. Never freeze.
Light protection: Store in amber vials or foil. UV light degrades peptide bonds.
Humidity: Keep dry. Moisture causes clumping and early degradation.
Contamination: Swab with alcohol before each draw. Never reuse needles or double-dip syringes.
