Missing or expired code? Tell us and we will update or remove it. Every vendor here is shown with its published score next to the offer, including vendors that have not cleared our third-party testing gate. A promo code never changes a score or rank. A sale or free-vial offer that needs no code counts toward the pricing sub-score only once it qualifies as a standing offer under our pricing rules (E and E1).

Peptide Promo Codes: Frequently Asked Questions
Are these peptide promo codes verified?
Offers are recorded from the vendor's own website or from the vendor's emails to us, and each entry shows where and when it was last confirmed. For vendors in our affiliate program, an automated check re-reads their homepage and recent emails daily, and reader codes are tested in the store's cart where the store allows it. A code-less sale that has not been re-confirmed within three weeks drops off on its own. If a code fails, tell us and we will remove it.
What's the biggest discount on this page?
As of 2026-11-05, the largest listed offer is Swiss Chems: up to 63% off (Sale: up to 63% off select SARMs, peptides and bioregulators). Swiss Chems scores 5.39/10 (Weak) in our independent audit.
Do these discounts or affiliate links affect your vendor rankings?
Affiliate relationships and promo codes are publicly disclosed and never change a vendor's score, rank, or testing gate. Every vendor listed here has a published, independently scored review. The first slots on this page are featured placements for affiliate partners and are labelled “Featured partner”; that is a placement choice, not a ranking, and the rest of the list is ordered by discount size. No placement or promo code ever changes a score or rank. A sale or free-vial offer that needs no code counts toward the pricing sub-score only when it has no stated end date, is not tied to an event or season, and has been live at two checks at least 30 days apart.
How often is this promo page updated?
For vendors in our affiliate program, an automated check re-reads their homepage and recent emails daily, and reader codes are tested in the store's cart where the store allows it. Offers from other vendors are recorded from their own website and drop off if they are not re-confirmed within three weeks. Each entry shows where and when it was last confirmed.
