About Prototides

Built around the analytical record.

Prototides is a research-grade peptide supplier organized around analytical documentation. Each compound is tied to a specific lot, and each lot to a traceable record available for review before purchase.

The catalog is kept narrow and the documentation deep — full, lot-specific provenance for every compound rather than broad coverage with limited support.

Why we exist

Built because the alternative wasn’t acceptable.

A research-grade supplier built on a single principle: if a number can’t be verified, it doesn’t belong on the label.

Prototides started as a frustration with the rest of the research-compound market: suppliers who’d quote a purity number with nothing behind it, COAs that arrived after the order shipped, batch records that didn’t survive a follow-up email. For a researcher evaluating material, an unverifiable number isn’t a convenience — it’s a liability.

Prototides exists to remove that liability. Every lot is tested before it’s listed, not after it’s questioned. We operate out of California, and the same person who reviews a lot’s documentation is the person who answers when you write in with a question about it.

The result is a catalog you can audit — not one you have to take on faith.

How we operate

Evidence over assertion.

01

Lot-level documentation

Every compound is tied to a lot, and every lot to a Certificate of Analysis, HPLC purity report, and LC-MS identity confirmation.

02

Independent confirmation

Representative lots are confirmed by an independent third-party lab before release — not just our own bench.

03

Defined, narrow catalog

Fewer compounds, with full documentation on each one, rather than broad coverage with thin support.

04

Verifiable, not promotional

Every number is checkable. No therapeutic or health claims — the analytical record stands on its own.

“Research materials should come with the same rigor as the research itself. If you can’t verify the compound, you can’t trust the result.”
