Every peptide is a sequence.
Pull the chain — then choose one to see the system it's researched for.
A synthetic fragment studied across tendon, muscle, and gut-lining repair.
Systems are the research contexts these compounds are studied in — not medical claims. For professional use only.
Best sellers.
The compounds researchers come back for. Every listing carries its own lot certificate.
What we make.
53 compounds, each assayed by HPLC and shipped with the certificate for its lot.
Find your compound by the question you're asking.
Ten research areas across the catalog — every listing HPLC-tested, sealed, and documented to the same standard.
Provenance you can read off the label.
Royal Empire Supply is a research-materials house with one rule: every lot ships with the paper to prove it. We test for purity, sign the certificate, seal the vial, and put the number in the open. The catalog is built for people who verify before they order — and expect the same of whoever sells to them.
A monograph for every compound.
Each peptide has its own page: sequence, the system it acts on, what it's been studied for, handling notes, and the research context — written straight, sourced honestly, with no claims we can't stand behind. It's the reference we'd want if we were the ones buying.
- Sequence & structure
- System & mechanism of study
- What it's researched for
- Handling & reconstitution notes
- Documented, not embellished

Browse by research area or search the catalog. Every listing links to its monograph and its documentation.
Check out in minutes. Your lot's Certificate of Analysis is yours to keep, on file with the order.
Tamper-evident vials, tracked and discreet, dispatched from stock held to the standard.
What researchers ask first.
What does “professional use only” actually mean?
Every compound we sell is supplied to qualified professionals for professional use only. It is not a supplement, drug, or food, and is not sold for human or animal use. We state it plainly because the framing matters as much as the material.
Do I get a Certificate of Analysis?
Yes — every lot ships with its COA, showing the lot number, HPLC-measured purity, and the laboratory that signed it. The certificate is tied to the exact batch you receive, not a representative sample.
How is purity verified?
By high-performance liquid chromatography (HPLC) on the specific lot. The measured value is what we print — we don't average across batches or quote a marketing figure.
How is an order shipped and stored?
Compounds ship sealed and tamper-evident, packed discreetly and tracked. Lyophilized peptides are shelf-stable for handling and transit; storage guidance for research conditions is included with the documentation.
Can I request bulk quantities or a specific lot's paperwork?
Yes. Use the research inquiry line for bulk requests, lot documentation, or questions a listing doesn't answer — a real person on our side handles it.
What these compounds are.
Peptides are short chains of amino acids. The 53 compounds in this catalog are grouped by the research area they are studied in, and each has a monograph covering what it is, how it is handled, and what the literature actually examines. Everything here is sold for professional use only.
