Report an issue with this profileWhy this score
The score card above, in plain words. Every line comes from the data we hold on this supplier, nothing is written by hand.
Extreme Peptide sits at 21 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: 9.5 of 25. 100–500 reviews on third-party platforms, and the average is fine.
Community: 6 of 20. Forum and Reddit talk is thin or cautious. Nobody has posted a verified review on PeptideScanner yet, so this rests on what is said elsewhere.
Transparency: 5.5 of 15. They say they provide third-party certificates of analysis.
We watch 42 of their products. Prices last checked 21 Sept 2026.
COA availability
The supplier's own published certificate is their statement. Our independent lab result is ours. We never merge the two.
Extreme Peptide states it provides third-party certificates of analysis for its products.
We have not independently lab-tested any product from this supplier. No PeptideScanner result is available — this is not a negative signal, just no data yet.

Community signals
A summary of public discussion — a sibling signal, distinct from our verdict and our own reviews.
Long-running US vendor with a real Trustpilot base (153) but strongly polarized: many 5★ 'long-time customer' reviews alongside a large 1★ share citing unshipped orders, no refunds, unresponsive support and inert product. reviews.io profile is negative (1.8/16). Listed on eroids; thepeptidereport affiliate review echoes 'mounting scam allegations'. No Reddit threads surfaced via site: search.

What the badges mean

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.
