We list a code only when a vendor shows it on its own site, and we say where we saw it. Next to the codes: free shipping rules, bulk offers and the price per mg of common research compounds, so you can see which deal actually costs less.
Checked by Dirk Westwood··Affiliate links: how we are paidEach ticket shows what the vendor publishes today. Click through and check the page yourself before you order.
Two names people still search for are closed: Peptide Sciences stopped selling in March 2026 and Amino Asylum closed in June 2025, per their own sites.
Lowest in-stock price per mg at each vendor. Shorter bar, lower price. All eight compounds
Lowest pricePSPeptides (our pick)Other vendors
Honest read: PSPeptides is not the cheapest on BPC-157. Ascension Peptides ($49 for 10 mg, on sale) and Swiss Chems come in lower per mg. PSPeptides is lowest of the vendors we checked on GHK-Cu, MOTS-c, KPV and Selank.
Same four steps for every vendor. The full method
Product pages, shipping pages and any promo or discount page on the vendor's domain. Never a coupon aggregator.
We write down the list price for each size, plus any sale price the page shows.
Price divided by milligrams, so a 5 mg and a 10 mg vial can be compared fairly.
Every entry carries its check date (Nov 6, 2026). A code says where it was seen and that we did not test it.
ITEM 01 / 05
On Nov 6, 2026 we found one code shown publicly on a vendor's own site: FIT10 on palmettopeptides.com, which the vendor says gives 10% off with no minimum. We have not tested it at checkout. The other vendors we checked showed no public code, only automatic bulk discounts, sale prices or email sign-up offers.
ITEM 02 / 05
Most codes on coupon aggregators cannot be traced to the vendor. Some are expired and some never worked. We only list a code when the vendor itself shows it on its own domain, and we say where we saw it and when.
ITEM 03 / 05
Not yet. Our affiliate code has not been issued. Until it is, the PSPeptides page lists only the offers the store shows publicly, such as free shipping and the 40% kit discount on 10 or more vials of the same peptide and size.
ITEM 04 / 05
Often, yes, if you need that many vials. A 40% kit price on 10 vials beats a 10% code, but only if your lab will use 10 vials of the same compound and size. For small orders, compare the price per mg and the free shipping threshold instead.
ITEM 05 / 05
No. Every vendor listed sells research peptides for laboratory research use only, not for human or animal use. This site covers prices and offers only.
