Research use only · 21 compounds · supplied by inquiry
Twenty-one synthetic peptides for qualified laboratories and licensed distributors. Every lot ships with a certificate from a laboratory we name — for the vial you were sent.
Accounts open in stages. Every inquiry is read. Not every inquiry becomes an account.
The Lot Standard
Purity is a claim until somebody independent measures it. There are five conditions. A lot that misses any of them stays where it is.
Tied to the lot in your vial, from an independent accredited laboratory, with that laboratory named. Plenty of suppliers show one certificate for a whole product line instead — a document describing material which existed somewhere, once.
Measured mass against expected mass. Purity tells you a sample is mostly one substance; identity tells you which one it is. We report both, on every lot.
A figure for that lot, with the method written beside it. A rounded number quoted brand-wide for two years tells you nothing about what shipped last week.
Lot numbers recorded against every shipment, cold-chain handling, storage conditions kept on the account. Ask about a lot eight months later and somebody can answer you.
Where an account imports, the paperwork a customs authority and a regulator expect travels with the shipment. Accounts in regulated markets are approved against their own licence.
So you can send it to any supplier and ask them to meet it — including us.

Including ours. Pick a compound and type the mass its certificate states. Nothing is uploaded and nothing is stored — the reference values ship with the page.
Reference · PubChem
Salt forms are recognised rather than failed: a trifluoroacetate adds 114.02 and an acetate 60.05.
The full check takes the laboratory, accreditation, lot, date, methods and net peptide content, and will compute the expected mass from a sequence.
Qualification
Qualification happens before anything is priced, which is why this catalogue has no cart and no public price list. We turn down a share of what we are asked for.
Opening an account
Against every shipment
What you hold at the end
A vial, and the paper that proves it.
There is no cart on this site. Pricing follows qualification, and orders inconsistent with the stated application are refused.
Refusals
Every line here costs us orders. We publish them anyway, because a supplier who will not tell you what they refuse has not told you much.
We do not publish it, we do not supply it, and we will not answer questions asking for it. Asking is a reason to close an account, not to open one.
We describe chemistry and what the certificate reports. Anyone promising you an outcome from a research compound is selling something that is not chemistry.
Materials are supplied for laboratory research only. Not for administration to people or animals, in any amount, by any route.
Semaglutide, tirzepatide and retatrutide are withdrawn deliberately. They are approved medicines whose compounding pathway is closing, and listing them as research material is the pattern regulators are currently writing letters about.
Pricing follows qualification. A supplier who will sell to anyone holding a card has told you what their verification is worth.
Availability is confirmed on account approval. We do not assert a catalogue in stock to look larger than we are.
