COA & lab verification
Public third-party COA published on-site (a 'Download COA' on the /coa-testing page). The certificate currently posted is a real Prime Analytical Laboratories, LLC report (Concord, CA — a named US lab with a verifiable address/phone): Tirzepatide 10mg lyophilized powder, sample #008060, 100.0% purity by HPLC, net peptide content 11.68mg, single clean chromatographic peak (report QU-1007). The site states COAs are available for every lot, but at review only this single certificate was actually downloadable (not yet a per-product/per-batch public library), and it's purity-only (no MS identity, endotoxin, sterility, or heavy-metals panel) — so the COA factor sits mid (~7/10): above on-request/unknown, below vendors with full per-batch public COA libraries. Per the owner, the brand is onboarding a new testing lab to expand per-batch COA coverage — re-rate the COA factor upward once those publish. Notes OUTSIDE the COA factor: new storefront (assets dated Dec 2025–Apr 2026) with no externally verifiable Trustpilot/Reddit/Eroids footprint yet (on-site testimonials are not independently verifiable, so not counted as social proof); founder is an established operator known in the space (owner-verified). Operations strong: Square cards + crypto/stablecoin checkout, full catalog in stock/ready-to-ship, 30% affiliate program, RapidFulfillment cold-chain 3PL fulfillment; strict 'all sales final' return policy. Entity: Peptide Research Labs Inc, 1309 Coffeen Ave STE 1200, Sheridan WY (a registered-agent address). PeptidePrices partnership disclosed per FTC; partner/affiliate status does not influence the rating.
Our verdict on GLP-1 Research Lab
Yes on the testing: GLP-1 Research Lab publishes a real third-party COA from a named US lab (Prime Analytical Laboratories, Concord CA) — the posted Tirzepatide report shows 100.0% purity by HPLC. The caveat is breadth, not legitimacy: one certificate is published so far rather than a full per-batch library, and it's purity-only.
It's a new but well-run storefront — an established operator, US-based, with card + crypto checkout, in-stock inventory, and professional cold-chain fulfillment behind it. There's no public review history yet, which is the main thing keeping it out of the top tier; expanding per-batch COAs (a new lab partnership is in progress) is the clear path up.
More about GLP-1 Research Lab
GLP-1 Research Lab (Peptide Research Labs Inc) is a US-based research-peptide supplier focused on the GLP-1 metabolic class (Semaglutide, Tirzepatide, Retatrutide, Cagrilintide) alongside recovery, GH-secretagogue, and longevity compounds. It publishes a third-party Certificate of Analysis from Prime Analytical Laboratories, a named US lab in Concord, CA — the posted Tirzepatide report verifies 100.0% purity by HPLC with net peptide content and a clean single peak.
The testing is real and third-party, which anchors the COA factor; what holds that factor mid for now is breadth — one certificate is published rather than a per-batch library on every product page, and the panel is purity-only. The brand is new, so there isn't a public review footprint to lean on yet, but it's run by an established operator and its operations are a genuine strength: card and crypto payment, in-stock inventory, a 30% affiliate program, and professional cold-chain fulfillment. Expect the COA coverage — and the score — to rise as its new lab partnership produces per-batch COAs.
