Never disappointing — consistent quality over multiple orders
Multi-year customer here. Cernum has never been disappointing. Third-party testing, certificates of analysis for every product, and over 99% purity are consistent standards I've seen across all my orders. USA-only shipping is fast and dependable. Pricing is higher than bargain options but aligned with the verification depth they offer.

Order never arrived — possible scam
Cernum is a scam and will try to steal money without sending orders. A month passed with no peptides received. I ordered from another reputable company afterward and received it within days. Cernum promised the order by February 17th, then promised overnight shipping when I emailed them, but still failed to deliver. Eventually stopped answering my emails.
