Why this page exists
Most coupon websites have untested and scrapped codes. However, in PeptideCrib, everything is done differently, and we have a public record of this.
The five-step process
- Hand testing. The codes get applied to the actual checkout of the merchant by an identified editor before they are published. There are no scrapped, recycled or guessed coupons on PeptideCrib.
- Screenshot proof. We take a screenshot of the applied discount in the shopping cart. The proof thumbnail gives you access to every proofed deal.
- Named accountability. Each promos has an editor who identified it. They have an identifier and their LinkedIn and author pages are connected too.
- Live reader feedback. Readers give feedback on whether they saved or not after publication. Votes create a success rate, which remains invisible until there are at least five votes for it. The report button allows you to alert us about non-working coupons immediately.
- Re-verification. Reported coupons are being re-tested by an editor. Those which do not work are deleted — we prefer having less codes to have outdated ones.
What our numbers mean
Both Total uses and Today’s uses take into account actual reveals and copies made on this website. Success rate means the percentage of readers’ votes confirming that the promo code really worked. Usage graphs on the vendor’s page represent actual usage statistics on a weekly basis. These numbers are never seeded, overstated, or invented – where there is no information, you will see nothing.
Every figure on a vendor page is a real, anonymised count from live activity on this site — never seeded, estimated upward, or invented. Where we lack enough data to be meaningful, we show nothing instead of a placeholder.
- Grabbed this week — reveals and copies in the last seven days, shown with an vs last week trend once the previous week has enough activity to compare fairly.
- Most popular — the code readers grab most on a vendor’s page; it sorts to the top and earns the badge only after genuine usage, never just for being newest.
- Worked % (success rate) — the share of ‘Did this work?’ votes saying the code worked, shown with its sample size (for example, ‘87% worked (23 reports)’) and hidden until at least five votes exist.
- Avg. saved — the average amount readers report saving with a code, shown only once several independent reports exist.
- Usage chart — real weekly reveal and copy activity on established vendor pages.
Our independence
We may earn affiliate commissions, disclosed on every page. Verification outcomes are never affected by commission rates: a code either works at checkout or it does not.
