One vial measured — over-fill beyond 115% is flagged, not rewarded.
Lab lookup run 29 Sep 2026: 'Document found'. 141% of label — over-fill flag.
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.
One point per criterion, no weighting, same rubric for every vendor — scoreboard.

Almost nothing: the only Reddit result for the name is a 2025 thread in an unrelated snark subreddit where a commenter mentions having looked at Offline Peptides' documentation. No user-experience thread, no warning thread, nothing about the payment rails.
An unrelated thread; a commenter says they 'looked at documentation from places like Offline Peptides'.
How this was read: Google's Reddit results for "Offline Peptides reddit" on 29 September 2026 — thread titles, subreddit, dates and the text visible in search. We did not read every comment, so a gist says what a thread is and what its visible text says, not what it concludes. Threads in a vendor-run or ranking-site subreddit, and listicles or coupon posts in unrelated subreddits, are labelled as such. None of this is an input to the score; the rubric reads evidence, not opinions.
Both are affiliate partners; we earn a commission either way, so this is not a steer. Same rubric, same dated prices.
Earns nothing Purgo doesn't.

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.

Yes — code CR10 gives 10% off, confirmed 29 September 2026 from the partner terms. Confirmed by the vendor's affiliate team by email 29 Sep 2026 (an earlier code was retired the same day). Not cart-tested; stacking with the site's '20% off sitewide' banner or its 5% Zelle/Cash App incentive is unknown. Checkout takes ACH/eCheck, Zelle and Cash App only — no card. It is an affiliate code: we earn a commission on orders that use it, which is disclosed here and does not affect the rubric score above.
