How this works

We publish. Prime ships.

Fresno Peptide Lab does not sell anything. We do not hold inventory, we do not set prices, we do not process payments, and we never touch an order. What we do is publish the clearest, most complete picture of the Prime Bio Group catalog that exists anywhere — 57 compounds, real product photography, live pricing, research summaries, and the COA context you need before you spend a dollar.

When you click through, you land on Prime's own store. They take the order, they bill you, they ship it. We may earn a commission on that order, at no additional cost to you. That relationship is disclosed on every page, because a site that hides it is telling you something about how it treats you.

Why Prime Bio Group

It is a physician-owned lab. Not a reseller, not a drop-shipper, not a brand layered on top of somebody else's powder. A practicing physician owns and runs it, which is why batch documentation is available on request rather than on a wish.

The catalog is genuinely deeper than the competition. Most research suppliers sell you a lyophilized vial and leave the hard part — reconstitution — to you. Prime stocks oral GLP-1, capsules, ready-to-use nasal sprays and finished topicals alongside the standard vials. Almost nobody else does.

A COA comes with every batch. Purity by HPLC, identity by mass spectrometry. Here is what that actually proves, and what it does not.

How we are related to Peptides Uncaged

Peptides Uncaged is our sister publication. It reviews and ranks research-peptide vendors independently, publishes plain-English compound guides, and scores suppliers on purity and COA transparency without pay-to-win placement. If you want a second opinion on this lab or any other, start there.

Research use only. Every compound referenced on this site is sold for laboratory and research purposes. Nothing here is for human consumption, and nothing here is medical advice. Read the full policy.
