Research-Grade Peptides.
≥98% Purity. Every Vial.

All Molecular Peptides products are verified at ≥98% purity. Each batch is independently tested by an accredited third-party laboratory and accompanied by a Certificate of Analysis (COA) documenting purity levels and identity verification.

Yes. A batch-specific Certificate of Analysis (COA) is available for every product and can be viewed and downloaded directly from our Certificates of Analysis page before or after purchase.

We ship to all 50 US states. Orders are fulfilled within 1-2 business days and shipped via USPS or UPS with tracking provided. All peptides are shipped as lyophilized powder, which is stable at ambient temperature during transit.

Lyophilized (freeze-dried) peptides should be stored at -20°C for long-term storage or 2-8°C (refrigerator) for short-term use. Reconstituted peptides should be stored at 2-8°C and used within 30 days. Avoid repeated freeze-thaw cycles to maintain peptide integrity.
