The score card above, in plain words. Every line comes from the data we hold on this supplier, nothing is written by hand.
Core Peptides sits at 26 out of 60. Middling. Most of the gap is reviews.
We have not lab-tested anything from them yet, so the 40 points for Lab Verification are off the table for now. What you see is built from three public signals.
Reviews: 0 of 20. We found no review record for them on the platforms we monitor.
Community: 7.5 of 15. Forum and Reddit talk is mostly positive, with some caveats. Nobody has posted a verified review on PeptideScanner yet, so this rests on what is said elsewhere.
Transparency: 18 of 25. They say they provide third-party certificates of analysis. We hold 300 of them; the newest is from May 2026. Of the certificates we list, 1 of 1 dated ones were issued in the last 6 months.
Too few of their certificates carry a readable vial or purity result to check against their claims, so that part holds a neutral 5 of 10.
We watch 12 of their products. Prices last checked 9 Oct 2026.
COA availability
The supplier's own published certificate is their statement. Our independent lab result is ours. We never merge the two.

Community signals
A summary of public discussion — a sibling signal, distinct from our verdict and our own reviews.
improving: independent blind lab test avg 96.4% purity across 5 compounds (real product, slightly under 99% claim), external reviews 4.8/279, Knoji 4.0/65, positive Reddit trend, top-5 rankings on multiple review sites; the corepeptides.ca scam clone drives most 'scam' hits (WhatsApp tax-fee demands, Jul 2026) and an outliyr 'entire scam' entry (Jan 2026) — attribution unclear; occasional fulfilment complaints on the real site remain

What the badges mean
We have independently lab-tested products from this supplier. The badge carries the test date and the named lab. Earned and rare — no supplier holds it yet.
Monitored but not yet tested by us — the default state for a supplier we are following. Trust Score capped at 60.
Documented counterfeit or non-delivery signals. Never presented as a recommendation in any sort order.
A published COA is not a badge tier. It is the supplier's own claim, shown separately above — never merged with our independent result.
