Linux Peptides review: is it legit?

Transparency score
10/100*
Six checks
Live Checked Oct 16, 2026 Visit linuxpeptides.com

Our findings in brief

In short: Linux Peptides scores 10/100 on the 4 of 6 checks we could complete, higher than 4% of the 197 active vendors we track. It isn't ranked until all six checks are complete (4 of 6 so far).

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

What's missing or unverified

Across 23 peptides that at least three vendors sell, its best prices are typically 77% below the median (23 of 23 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 box of 10 vials, with no order minimum. 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. 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.
