Answers for orders, shipping, product quality, payment, returns and restocks. UK-based support, real humans.
Yes. The compounds we've had tested are HPLC-verified by Janoshik Analytical, an independent Czech laboratory, and each of those certificates names Grey Matter Peptides as the client — an own-name report, not a borrowed one. Every report carries a verification key you can authenticate yourself against Janoshik's own portal at janoshik.com, so the evidence is checkable at source rather than taken on trust. See the plain-English answer with live certificates on the Is Grey Matter Peptides legit? page.
An own-name certificate of analysis names the supplier itself as the client who submitted the sample. Many suppliers instead show a certificate naming a different company — a borrowed or generic report that doesn't prove your batch was tested. Our Janoshik certificates name Grey Matter Peptides, and each carries a verification key you can check at janoshik.com.
