Frequently Asked Questions

Peptides are short chains of amino acids (typically 2-50) linked by peptide bonds. They act as signaling molecules in biological systems, directing cellular processes from hormone production to tissue repair. The human body naturally produces over 7,000 peptides.

Pharma-grade (or cGMP) means products are manufactured in facilities meeting pharmaceutical-style standards: controlled environments, validated processes, and quality control. We don’t manufacture or test; we prioritize retailers that offer products from such sources and, when available, COA documentation.

We don’t process orders. Shipping and free-shipping thresholds are set by the retailers we link to. Check each retailer’s site for current shipping policy.

Add bacteriostatic water to the lyophilized peptide vial by slowly running the water down the inside wall. Gently swirl — never shake. Use our free peptide calculator for exact volumes and concentrations. Read our complete reconstitution guide for step-by-step laboratory instructions.
