Amino Club is a U.S.-facing research-peptide reseller that looks operational rather than a documented scam, but it carries real caution flags: a first-hand wrong-compound delivery, heavy coordinated coupon promotion, and quality claims that rest on its own paperwork.

Identity: aminoclub.com, a self-described U.S.-based supplier selling GHK-Cu, tesamorelin, retatrutide, BPC-157, TB-500 and NAD+ behind a researcher-verification gate.

What the evidence shows

• The requester ordered GHK-Cu and tesamorelin and received tesamorelin plus retatrutide instead of the GHK-Cu. That is a wrong-compound substitution and a real safety concern, standing as one unverified first-hand account.
• Promotion dominates the footprint: a single account reposted the same discount code across 10-plus referral subreddits, and other coupon codes circulate the same way.
• Independent buyer sentiment is thin. One r/Biohackers user said a GHK-Cu order arrived and behaved as expected; a separate thread called the pricing a marked-up ripoff versus sourcing direct.
• COAs and a 99%-or-higher purity guarantee are seller-published, with no batch-linked independent test found in the sources reviewed.
• A commenter challenged the U.S.-based framing against where the product is actually made.

What it does not show

No independent scam, non-delivery, or fake-tracking reports surfaced in the Reddit and forum sources reviewed. Absence of complaints is not proof of purity or dosing, and a seller-published COA is not independent batch verification. Promotional posts are not independent feedback.

Low documented scam risk, but the substitution and unverified testing warrant caution until an independent batch test and a clean repeat order are confirmed.
