Transparency, as a standard.

The research peptide market suffers from a simple problem: too many promises, too little proof. Weptide was founded on the opposite principle — data before discourse.

Why we exist

A researcher ordering a compound needs one thing only: to know exactly what they are receiving. Not a sales pitch, but a confirmed molecular identity and a measured purity. That's what we deliver with every vial — a batch-specific certificate of analysis, viewable at any time.

We are not an anonymous middleman. Every reference in our catalogue goes through the same control protocol, without exception and without shortcuts.

Quality is not optional

Our control chain relies on recognized analytical methods, applied systematically:

• Reverse-phase HPLC — to confirm purity above 99% and detect the slightest impurity.
• Mass spectrometry — to verify the compound's identity and exact molecular mass.
• Certificate of analysis per compound — each of our peptides is associated with its own dated, signed COA.

End-to-end traceability

Every compound is linked to its certificate of analysis, its synthesis date and its test results. No grey areas: if a number exists, you can verify it.

A strict framework, fully embraced

All our products are intended exclusively for laboratory research and in vitro use. They are neither medicines nor supplements, and are in no case intended for human or animal consumption, nor for diagnostic or therapeutic use.

This framework is not a constraint we endure: it is the mark of a serious supplier. We make no health claims and give no advice about use on the body. Our job stops at the laboratory door — and that's exactly as it should be.
