A short catalog,
superior peptides.
10 compounds, selected for how well they can be characterised, documented, and supplied to a consistent specification. Every batch is analysed by an independent laboratory, and its certificate is yours on request. Ordering is private, by conversation — never a checkout.

We do not process card payments and we do not operate a shopping cart. Every order begins as a request, is reviewed by a person, and is confirmed by email before anything is dispatched.
- 01
Submit a request
Tell us the compounds and quantities your protocol calls for. No account, no cart, no payment details — a request is not an order.
- 02
We confirm and quote
We verify availability, confirm the batch and its analytical documentation, and reply with pricing and lead time by email.
- 03
Fulfilment
Once you approve the quote, we arrange payment and dispatch directly with you. Ask for the batch certificate at any point and we send it.
Requests are non-binding. Payment is arranged directly with us after you approve a quote, never through this site.
Every batch is tested. The paperwork is yours on request.
Purity is established by reverse-phase HPLC and identity confirmed by mass spectrometry. A certificate of analysis is generated for every batch we supply. Ask for it — with an order or long after one — and we send the certificate matching your lot.
How we test- 01 — Purity
Reverse-phase HPLC with the chromatogram included on the certificate.
- 02 — Identity
Mass spectrometry confirming molecular weight against the expected value.
- 03 — Traceability
Lot number printed on the vial, matched to the certificate held for that batch.
- 04 — Handling
Lyophilised material stored and shipped under conditions stated on each product page.
A supplier should be boring in the right ways.
Batch-matched documentation
Material without paperwork is material you cannot cite. Every batch is analysed and carries its own certificate — never a generic sample certificate reused across batches. Request it whenever you need it.
A narrow catalog, held deliberately
We stock a small number of well-characterised compounds rather than an exhaustive list. Fewer items means tighter control over storage, handling, and batch traceability.
No guidance we are not qualified to give
We supply materials and their specifications. We do not advise on protocols, preparation, dosing, or administration, and we decline orders that suggest non-research use.
These materials are for laboratory research. Nothing else.
Products supplied by Reta Research LLC are not drugs, foods, cosmetics, or medical devices. They are not for human or animal consumption, and not for any diagnostic or therapeutic use.
