Peptide vendor warning
Community Warning!
FDA issued a Warning Letter to SwissChems on December 10, 2024 (MARCS-CMS 695663) for selling unapproved GLP-1 drugs (Semaglutide, Retatrutide) marketed for human use despite research-only disclaimers. Finnrick Analytics score of 3.6/10. Multiple review aggregators (PepPal, IronPeak) do not recommend the vendor. Trustpilot profile for swisschems.io shows 86% one-star reviews across 14 reviews. Complaints include expired products on delivery, payment friction (BTC preferred, 5% card surcharge), no refunds for seized international orders, and inconsistent peptide COA quality (in-house rather than third-party testing).

Reliable results and consistent quality on SARMs
Reliable results and consistent quality for SARMs orders. Peptide COAs were a bit hit-or-miss and one vial showed clumping, but overall I keep coming back.

Expired product received — 3 years past expiration

Not the fastest delivery — 2 weeks to my door
Not the fastest delivery. About 2 weeks until it reached my door which I think is quite a lot.

BEWARE — order unfulfilled after 2+ months, zero communication
BEWARE — SWISSCHEMS IS A THIEVING SCAM! Placed an $800+ order and received nothing after more than two months. Zero communication from support, which has become completely unresponsive. Do not trust this company with large orders.
