How the score breaks down
Hydro Research scored across our four rubric factors — COA practices (40%), reputation, transparency, and operations (20% each).
Weighted factor result: 8.4/10. Final published score: 9/10. This editorial adjustment is disclosed because the final score differs from the weighted result; for Hydro Research, verified COA evidence sets the published floor.

COA & lab verification
Best-in-class, verifiable COA program: a public on-site lab-results library (64 products / 196 documents) with batch/lot-specific reports surfaced on each product page. Named third-party labs — Janoshik (purity/content) and Chromate Labs (heavy metals) — plus endotoxin and sterility testing; stated scope covers purity, identity, endotoxin, heavy metals, and sterility. Verifiable example: the R40 (Retatrutide 40mg) page shows a Janoshik COA dated 2025-07-29 at 99.834% purity. This breadth + named-lab linkage is genuinely above-average. ⚠️ Flags sit OUTSIDE the COA factor (see profile): no physical address or founding year published, WHOIS hidden, the store transacts under a different payee identity ('Hydro Consulting / AstroLLC' on Venmo), and GLP-1 product names are obfuscated behind codes. COA library/labels verified plus one product's values — not every individual document. ✅ 2026-06 update (rating 8→9): now an affiliate partner with a 15%-off code (PEPTIDEP15); accepts returns within 30 days of delivery on unopened items in original condition; and after being removed from Trustpilot (customer reviews used weight-loss/treatment/health-claim wording that violates Trustpilot's policy for research-chemical sellers) they now show 4.9/5 across ~1,600 reviews on PepReviewPro (linked on the vendor page). The added reputation + returns clarity, on top of the best-in-class COA program, lift the score to 9.
Our verdict on Hydro Research
Strong — Hydro Research has one of the most thorough public COA programs we track: a real on-site library of batch-linked reports from named third-party labs (Janoshik + Chromate) covering purity, heavy metals, endotoxin, and sterility. Pair that with fast 2-day FedEx fulfillment and card payment and it scores at the top of our COA and operations factors.
The one thing keeping it from the very top is corporate transparency, not the lab work: no published address or founding year, a hidden WHOIS, a separate Venmo payee identity, and coded compound names. The organic feedback that exists is positive, so this is a solid choice for the testing depth — verify your batch's COA yourself, lean on reversible card payment over Venmo, and treat the thin corporate disclosure as the open item.
More about Hydro Research
Hydro Research (hydroresearchpeptides.com) is a US-only research-compound supplier with a broad GLP-1-heavy catalog — Retatrutide, Tirzepatide, Semaglutide, Cagrilintide and several GLP-1 blends, plus the usual recovery (BPC-157, TB-500), GH-secretagogue, nootropic, and longevity compounds. Notably, the GLP-1 products are sold under obfuscated codes on-site (H-(R) = Retatrutide, H-(T) = Tirzepatide, H-(S) = Semaglutide, etc.); we've decoded them to the real compound names.
The standout is testing, and it's best-in-class: a public on-site lab-results library (64 products / 196 documents) with batch/lot-specific reports from named third-party labs — Janoshik for purity/content and Chromate Labs for heavy metals — plus endotoxin and sterility testing. Full-panel, batch-linked, named-lab testing is exactly what our 40% COA factor rewards most (e.g. the Retatrutide 40mg page links a Janoshik COA at 99.834% purity). Operations match it: fast 2-day FedEx, same/next-day dispatch, free shipping over $200, and card payment.
Reputation is solid where it counts — the organic third-party feedback we found is positive (researchers reporting real product that arrives with a COA), and the domain has been established for several years rather than being a fresh storefront. The one genuine caveat is corporate transparency: no physical address or founding year is published, WHOIS is hidden, the store takes Venmo under a separate payee identity ('Hydro Consulting / AstroLLC'), and the GLP-1 names are obfuscated behind codes. None of that touches the (strong) lab data — it's just opacity worth knowing about.

Review Highlights
Positive
"Reliable source for research. Great supplier — the compound arrived exactly as described and reconstituted perfectly. The subject's readings during the observation period were encouraging and consistent."
"Great turnaround time. Clean product, fast delivery, fair pricing. The research subject found the compound to be of excellent quality. Simple as that."
"Superior product integrity. Second order from this vendor — quality remains consistent between batches, which is exactly what a serious researcher needs. Reconstitution was smooth and the solution was crystal clear."
