Every code below is one we hold and have confirmed on a date. Next to each one: the vendor's score on the same 10-point evidence rubric we apply to all 77 vendors, so you can see who you are getting the discount from. No scraped codes, no expired ones, no guesses.

A 20% code on an underdosed vial is not a saving. The rubric column is the same ten checkable criteria — named laboratory, certificates that resolve on the laboratory's own site, measured milligrams against the label, published legal identity, an independent review record — that order the Best Peptide Vendors scoreboard. Where a vendor scores below others on this page, the per-criterion reasons are on its review.
60 of the 77 scored vendors. We would rather list them honestly than paste a code we have not confirmed. Scores shown for reference.
By size, Purgo Labs's code HEALTH (20% off every order, confirmed 6 September 2026). By documentation, the vendors scoring highest on our rubric with an active code are Purgo Labs (HEALTH, 20% off every order), MyPurePeptide (HEALTH, 20% off), Peptide Giants (health, 10% off). The table shows both so you can trade one against the other.
We publish a code only when it is one we hold as an affiliate partner and have confirmed on a dated dashboard, email or checkout. 60 of the 77 vendors we score have no code we can verify; we list them below rather than guess. If you run one of those vendors and want to be listed, use the vendor-alerts form on any review page to reach us — the scoreboard score will not change either way.
Usually not, and we say so per row where we have not cart-tested it. Several vendors show a permanent struck-through 'sale' price; a code may apply on top or may be refused. Check the cart total before paying.
Not yet. Each vendor issues its own string; several of ours are HEALTH, and SKO Compounds and EZ Peptides use COMPOUNDREVIEW. We are asking partners to accept COMPOUNDREVIEW as an alias everywhere; when that changes this page will say so with a date.
Every code here is an affiliate code: we earn a commission on orders that use it or arrive through our link. That is disclosed on every code page and here. It has no input into the rubric score shown next to each vendor — several partners score below non-partners on the scoreboard.
