Peptide Storage Guide - Before & After Reconstitution

5 min read

Why Storage Matters

Peptides are delicate molecules that can degrade when exposed to heat, light, moisture, or bacteria. Proper storage is essential for maintaining potency and safety.

Before Reconstitution (Lyophilized Powder)

• Short-term (up to 3 months): Room temperature, away from light
• Long-term (up to 2 years): Refrigerated at 2-8 degrees C
• Extended storage: Frozen at -20 degrees C for maximum stability

After Reconstitution

• Always refrigerate at 2-8 degrees C
• Never freeze reconstituted peptides
• Use within 3-4 weeks for most peptides
• Keep in original vial

Peptide-Specific Storage Times

BPC-157: 3-4 weeks refrigerated. TB-500: 3-4 weeks. Semaglutide: 6-8 weeks. Tirzepatide: 6 weeks. Ipamorelin: 4-6 weeks. MOTS-c: 7-10 days. Selank/Semax: 2-3 weeks.

Signs of Degradation

• Cloudiness or particles in the solution
• Color change
• Unusual smell
• Clumping that won't dissolve
