Verification
Independent COA.
Every batch. Published.
Third-party lab — not us
Every compound is tested by an independent laboratory with no financial interest in the result. The COA comes from them. We just publish it.
99%+ purity on every report
We don’t ship until the COA confirms 99%+ purity. Below that threshold, the batch doesn’t ship. No exceptions, no negotiation.
Published before you buy
Every COA is live at evopeptidesus.com/coas/ before you place an order. Batch number, purity percentage, identity confirmation — visible before checkout.

Why Evo Peptides
Not just claims.
Proof.
Independent COA on every single batch
We don’t test our own compounds and report back to you. An independent third-party lab tests every batch and publishes the results publicly before you order. That’s the only way COA verification means anything.

FAQ
Common questions.
Evo Peptides is a Wisconsin-based research peptide supplier offering independent COA-verified compounds including GLP-3 RT (Retatrutide analog), GLP-2 TRZ (Tirzepatide analog), BPC-157, TB-500, GHK-Cu, NAD+, Selank, Semax, MT-1, MT-2, KLOW, and Bacteriostatic Water. All compounds are tested at 99%+ purity by an independent third-party lab. Same-day shipping on orders before 3PM CST from Wisconsin. For research use only.
A Certificate of Analysis (COA) is an independent third-party laboratory document confirming the purity, identity, and batch number of a compound. COA-verified means an external lab — not the manufacturer — tested the compound and confirmed 99%+ purity. Evo Peptides publishes every COA at evopeptidesus.com/coas/ before you order.
Yes. Research peptides are legal to purchase in the United States when sold for laboratory and in-vitro research use only. They are Research Use Only (RUO) compounds — not drugs — and require no prescription. Evo Peptides sells all compounds strictly as RUO materials, not for human consumption.
Yes. Orders placed before 3:00 PM CST ship the same day from our Wisconsin facility via USPS or UPS with full tracking. Free shipping on all orders over $100. Delivery typically takes 2–4 business days domestically.
Three things you can verify: an independent COA published before you buy (not after), same-day shipping from a real US address (not an overseas warehouse), and purity confirmed at 99%+ by a third-party lab (not a self-reported claim). Cheaper alternatives skip one or all three of these.
