What we found at Offline Peptides

Read 29 September 2026 on the vendor's own pages

The certificate chain is real and lab-confirmed, prices are open, and 99 Trustpilot reviews say the orders arrive. What is missing is the two things a buyer leans on when they don't: a company name and address, and a payment rail that can be disputed. A vendor that takes only Zelle, Cash App and eCheck — and pays you 5% to use the first two — has moved the risk onto you. 8/10 on the paperwork; weigh the rails.

Score history and the caveats

A score only moves when the evidence does

2026-09-298/10 — first assessment (rubric v2); not awarded: identity (no entity or address on site), clean-record (ACH/eCheck, Zelle, Cash App only — no card; 5% off for Zelle/Cash App) — lab search code confirmed at the lab; 14.12mg on a 10mg label flagged

Purgo Labs: the caveat

Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.

Offline Peptides: the caveat

Checkout takes ACH/eCheck, Zelle and Cash App only — no card — and gives 5% off for Zelle or Cash App, so a buyer has no chargeback route; that costs the clean-record point. No legal entity or street address on the site (two toll-free numbers and an email; a trademark filing names Offline Peptides, LLC, but the site does not). The certificate we opened measures 14.12mg on a 10mg label — 141% of label, over our 115% flag line. All sales final at the vendor's discretion. An age-and-researcher attestation sits in front of every page.
