M-MPS links each product to a batch coded Janoshik lab report, but payment is crypto only and the store itself warns that an incorrect transfer is "a direct loss and cannot be recovered."

The newly launched US self-checkout site of M-Peptides Science (MPS), a China-based peptide vendor, at m-mps.com.

Where it trips our checks

• Irreversible payment: the only routes are USDT, USDC and Bitcoin, with no card checkout anywhere. Crypto-only payment with no chargeback is a pattern we see repeatedly around bad actors.
• Purchase protection: the "replace or refund unconditionally" promise is seller-stated, with no independent dispute path behind it.
• Contact transparency: branded emails and official groups exist, but there is no registered company or address, and the storefront is disguised as a bead shop titled "M Beads."

Bottom line: No scam pattern found, one glp1forum buyer reports a clean delivery, and the posted COAs link to per batch Janoshik reports, but crypto-only checkout means a bad order cannot be clawed back. Likely not a scam, use normal caution.
