About Certified Peptides

Certified Peptides is a US-based vendor headquartered in Rochester, Washington, with production facilities in Texas operating under GMP-compliant conditions. They offer comprehensive third-party testing at an ISO/IEC accredited facility covering purity, endotoxins, heavy metals, and bacteria, with results showing 99%+ purity. The company sells peptides in multiple formats including vials, capsules, and topicals. Certified Peptides is known for fast shipping with same-day and next-day fulfillment options, offering both USPS Priority (3-5 days) and FedEx 2-Day Air. While their testing standards are strong, the company has limited online reviews and pricing transparency could be improved.

A COA describes one batch's purity. It is a document about a vial, not evidence about an effect, and it never grades a claim on this site — the grading rubric names what qualifies.

Linked names have a record here; the others we hold nothing on yet. A vendor listing a compound says nothing about the evidence for it.
