Why PeptideCrib exists
There are many sellers, great variability of prices and almost no independent and verifiable data on this market. Sites where coupon codes can be found usually just redistribute scraped codes, while sites where reviews can be found do not inform about the way of scoring. PeptideCrib was created in order to solve these problems: all promos are manually checked, and screenshots are provided for each review which is evaluated according to six published criteria by a named editor.
What makes us different
- Proof, not promises. A code only goes live after an editor applies it at the vendor’s real checkout and attaches a dated screenshot.
- Real statistics only. Use counts, success rates, and usage charts come from live tracking on this site. Where we lack data, we show nothing rather than an invented number.
- COA transparency scored. Every review rates whether a vendor publishes third-party Certificates of Analysis — the single most important quality signal in this market.
- Named accountability. Each page carries the name of the editor who verified it, linked to their author page and LinkedIn profile.
