We started with one molecule.
ss31-peptide.shop began as a single-compound supplier of SS-31. The catalogue is still deliberately small, and every addition is held to the same documentation.
SS31 Peptide is a specialist research peptide supplier. The shop began as a single-compound source for SS-31, and the catalogue is still deliberately small so that every product can be held to the same documentation.
A research peptide supplier with a short catalogue
Most peptide catalogues run to hundreds of listings. Ours runs to five compounds. That lets us keep full analytical records for each one and answer specific questions about any lot we have shipped.
SS-31 peptide remains the centre of what we do, offered across four purity grades and in sizes from single research vials to bulk quantities. Alongside it we carry BPC-157, GHK-Cu, Retatrutide and TB-500, four peptides that appear consistently in current published research and in the requests we receive.
What to expect from us
As a research peptide supplier, our job is narrow: supply the stated compound, at the stated purity, with the documents to show it. Each lot is checked by HPLC and mass spectrometry, the standard methods described in this overview of HPLC, and the results are stated on its Certificate of Analysis.
We do not publish protocols and we do not make claims about outcomes. Product pages describe what a peptide is and what the literature studies it for, and nothing more.
Wholesale supply
We supply laboratories, institutions and resellers on a wholesale basis from a minimum order of 50 units. Larger quantities are welcome. Use the contact page to tell us what you need.
How we work
- Documentation first
- Purity by HPLC and identity by mass spectrometry are recorded for each lot and stated on its Certificate of Analysis.
- A short catalogue
- We add a compound only when we can support it with the same analytical record and storage guidance as SS-31.
- Plain language
- Product pages describe what a peptide is and what the literature studies it for. They do not suggest uses outside the laboratory.
- Qualified buyers
- We sell to researchers, laboratories and institutions who accept that every product is for research use only.
