Current sale — stacks with your code

Hydro Research is currently running a sitewide sale, applied automatically at checkout — there's no separate code to enter for the sale itself:

50% off GLP compounds (Tirzepatide, Retatrutide, Semaglutide).
25% off everything else.

The standing PROFPEPTIDE code stacks on top of the sale price for an additional 20% off — enter it at checkout as usual, the same way you always have.

Sale runs through September 14, 11:59 PM. Outside the sale, PROFPEPTIDE takes 20% off any order, permanently. Sale terms are set by the vendor and can change.

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 — roughly 270 documents across its catalog — 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.
