Hydro Research (hydroresearchpeptides.com) is a US research-peptide supplier with a catalog of roughly 70+ products spanning single-compound peptides, combination blends, packs, capsules, and dropper formats, organized by research area. Popular compounds by research area:

Metabolic & Weight Loss
Retatrutide (H-(R)), Tirzepatide (H-(T)), Semaglutide (H-(S)), Cagrilintide (H-(C), an amylin analog, not a GLP), plus combination vials: a Cagrilintide + Tirzepatide vial (H-(C-T)) and a CagriSema (Cagrilintide + Semaglutide) vial (H-(C/S))
Recovery & Repair
BPC-157, TB-500, and a BPC-157/TB-500 blend
Skin & Other
GHK-Cu, MOTS-C, AOD-9604, SNAP-8, and additional research compounds

Hydro Research lists its metabolic peptides under coded names — H-(R), H-(S), H-(T), H-(C) and combination vials — so a buyer recognizes the store listing. The compound behind each code is identified on that product's Certificate of Analysis: the H-(R) Janoshik report tests Retatrutide, H-(S) tests Semaglutide, H-(T) tests Tirzepatide, and H-(C) tests Cagrilintide (an amylin analog, not a GLP).

Hydro Research publishes a public Certificate of Analysis library whose header states its own size — “74 products 275 documents”, the vendor’s figures, quoted rather than counted by us — with testing split across three laboratories: Janoshik (purity), Chromate Labs (identity), and ILS-Lab, alongside endotoxin, heavy-metal, and sterility screening. Its differentiator is independent portal verification: each purity report links to the testing lab's own records — Janoshik reports verify at janoshik.com with a unique key, and Chromate Labs reports verify at chromate.org — so a certificate can be authenticated on the lab's site rather than trusting a downloaded PDF. See the Hydro Research lab-results library.

Note on the store: Hydro Research's product pages require a free account — you'll need to register (no purchase) to view individual products and pricing. The lab-results library is viewable without an account. All products are sold for laboratory and research use only.

Frequently Asked Questions

Does Hydro Research have a coupon code?
Yes. Use code PROFPEPTIDE at checkout to save 20% on your Hydro Research order — a permanent standing discount. This code is verified and maintained by Prof. Peptide.
How much do I save at Hydro Research?
PROFPEPTIDE takes 20% off any order, permanently. Hydro Research has run sitewide sales on top of that in the past, applied automatically at checkout with no separate code; PP does not track whether one is running today, so check the storefront for a current promotion.
Do the Hydro Research codes stack?
Yes. Hydro Research's sitewide sales apply automatically at checkout, and the standing PROFPEPTIDE code stacks on top of the sale price — the vendor confirmed by email that "your existing affiliate discount codes will continue to work as usual". There's no separate "sale code" to enter; apply PROFPEPTIDE at checkout the same way you always have. Sale terms are the vendor's and can change.
What are H-(R), H-(S), H-(T), and H-(C)?
Hydro Research lists its metabolic peptides under coded names. The compound behind each is identified on that product's Certificate of Analysis: H-(R) is Retatrutide (Janoshik report names Retatrutide), H-(S) is Semaglutide, H-(T) is Tirzepatide, and H-(C) is Cagrilintide — an amylin analog, not a GLP. The combination vials are H-(C-T), a Cagrilintide + Tirzepatide blend, and H-(C/S), a Cagrilintide + Semaglutide (CagriSema) blend — both named on their Janoshik certificates. Each certificate is independently verifiable on the testing lab's own portal.
How does Hydro Research test its peptides?
Hydro Research's Certificate of Analysis library states its own size in its header: 74 products, 275 documents. It is public, with testing split across three laboratories: Janoshik (purity), Chromate Labs (identity), and ILS-Lab, plus endotoxin, heavy-metal, and sterility screening. Its differentiator is portal verification: Janoshik purity reports verify at janoshik.com with a unique key, and Chromate Labs reports verify at chromate.org — the certificate can be authenticated on the lab's own site rather than trusting a downloaded PDF.
