Most research peptides aren't what the label says. Here's how to prove yours is.

Research Use Only

A certificate of analysis with an HPLC trace beside a caliper — verified to the lot, on-chain COA.

Here's the dirty secret of research peptides: most of what's sold online isn't what the label claims — underdosed, impure, or the wrong compound entirely. And a generic 'certificate' proves nothing, because it isn't tied to the vial in your hand. So we did the opposite.

Verified on-chain

Don't take our word for it.

Batches tested

Every batch is independently tested by a US lab and recorded on-chain via Authentichain — so you can check our work, not just trust it.

Verify it yourself

Thirty seconds, three steps.

1

Find your lot number

It's on your vial label and at the top of your certificate.

2

Match the numbers

HPLC purity and mass-spec identity, run on your exact batch by an independent US lab.

3

Check it on-chain

Pull the record up on Authentichain. No vendor can fake it or quietly edit it after the fact.

Why it matters more than price

An in-house COA is grading your own homework.

A third-party, on-chain certificate is the only kind you can actually trust — the lab has nothing to gain from the result, and the record can't be changed later. That's the whole game, and almost nobody else plays it.

Tried dozens of vendors before this one. The COA actually matches the vial, every single time. Axos is in a different league.

I started Axos because a vendor once sold me garbage backed by a COA that turned out to be fiction. Never again — not for me, not for you. If you ever test a vial and it comes back under 99%, we refund the peptide and the cost of the test.

P.S. — Tomorrow: how to store your vials so they're still 99%+ when they reach the bench. Small mistakes ruin good peptides.
