International Peptides review: is it legit?

Transparency score

35/100

Six checks

Live Checked Oct 16, 2026 Visit intlpeptides.com

Our findings in brief

In short: International Peptides scores 35/100, higher than 35% of the 197 active vendors we track. It's #67 on our best peptide vendors list.

We haven't lab-tested anything from International Peptides, so this covers public evidence only, not product quality. As of Oct 16, 2026:

What checks out

Publishes shipping, refund and terms pages

What's missing or unverified

Publishes only generic or sample COAs, not batch-specific ones
Publishes an address but no company name
Domain registered only under a month ago
No card or PayPal payment stated (lists only Interac e-Transfer, Venmo, Wise and crypto, none of which carry buyer protection)

Across 30 peptides that at least three vendors sell, its best prices are typically 83% below the median (30 of 30 below). Compare its prices. Some of its listings are priced more than four times from the typical price: its own per-mg figures match our reading, and we haven't bought or tested its products.

Also worth knowing: Sells by the sealed box of 10 vials to trade accounts only: prices are public, but ordering needs an account. Its homepage calls it one storefront of a wholesale supplier and says the site opened in September 2026. Peptides Wholesale Canada, Peptides Wholesale USA, International Peptides and Linux Peptides use the same product codes (RT30 is a box of ten 30 mg retatrutide vials on each), the same category names and the same business hours, so they appear to be storefronts of one supplier. Peptides Wholesale USA and International Peptides also give the same address (2810 Crossroads Dr #4200, Madison, Wisconsin) and phone number, and charge the same prices (a box of RT10 is $76.00 at both). Sources are in the evidence list.

Prices come from each vendor's public product feed and were last fetched Oct 16, 2026. They exclude shipping and discounts. $/mg uses the labeled amount, not measured content. Listings marked "far below other vendors" (or above) are priced more than four times from the typical price; the store's own per-mg figure matches our reading, and we haven't bought or tested the product.
