We’re Osae Research, a peptide shop in Phoenix, Arizona. We supply research compounds for labs that want clean material and a paper trail that actually matches the vial.

A lot of this market looks polished until you ask about the lot. We built Osae so that question is easy. Independent US labs check what we sell. If purity and identity do not land where they should, the batch does not ship. Full stop.

What “tested” means here

Every lot on the shelf has third-party testing and a batch-matched certificate of analysis. On products where we say it, that means 99%+ HPLC purity, plus confirmation that the compound is the compound. You get the same COA we review before a box leaves Phoenix.

We are not trying to sound like a white paper. We are trying to make it obvious that purity is not a marketing line.

How the shop feels

Eligible orders go out the same day, packed cold. Free shipping at $200. A person on the other end if you need one. As we add sizes and compounds, that bar stays put. New catalog, same rule.

If that sounds like your kind of supplier, start with the shop or the lab results.

For laboratory research only. Not for human or veterinary use.
