All Apex Growth peptides are guaranteed 99%+ pure, and every batch is 8x tested at an independent ISO 17025 accredited U.S. laboratory: peptide purity (HPLC), net peptide content, identity, appearance, fentanyl screen, heavy metals (ICP-MS), sterility (PCR), and endotoxin. The full Certificate of Analysis (CoA) for every batch is published on our CoA page.

Sealed lyophilized (freeze-dried) vials are heat-stable and keep well at room temperature in a cool, dark place. Refrigerating or freezing sealed vials is optional; stability doesn't change much either way as long as the vial stays sealed. Properly stored lyophilized peptides have a long shelf life.
A Certificate of Analysis is an official lab document that verifies the quality of your peptide lot. Key sections include: Peptide Purity (should be 99%+), Net Peptide Content (measured mg vs the label), Identity (confirmed against a certified reference standard), Appearance, Fentanyl Screen, Heavy Metals, Sterility, and a quantitative Endotoxin result. Each CoA is batch-specific: find it on the product page or scan the QR code on your vial.
