The score card above, in plain words. Every line comes from the data we hold on this supplier, nothing is written by hand.
NuScience Peptides sits at 27 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: 6.4 of 20. under 50 reviews on third-party platforms, and the average is high. We discount review sites a little, so a strong record does not max this on its own.
Community: 4.5 of 15. 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: 16.5 of 25. They say they provide third-party certificates of analysis. Of the certificates we list, 13 of 38 dated ones were issued in the last 6 months.
Their own certificates against their claims: 3 of 33 measured vials are within 3% of the label (27 overfilled, 3 underfilled); 6 of 48 certificates fall below the 99% purity they advertise. That earns 3.9 of the 10 points for matching claims.
We watch 24 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.
- Products with a lab certificate
- 21 of 2488%
Of the products in the table below. Any tested size counts. The certificate must come from an independent lab and test the peptide itself.
- Found on the lab's own website
- 9 of 49certificates
We look each certificate up with the lab that issued it, where the lab has a public lookup. Many labs have none, so a low number is not a bad sign.
- Contamination tests
- 5 of 49certificates
Endotoxin 2 · sterility or microbial 5 · heavy metals 0. A certificate can have more than one.
How we count this · Certificates on file as of 8 Oct 2026. They include every size and batch we hold, so there can be more certificates than products.

Community signals
A summary of public discussion — a sibling signal, distinct from our verdict and our own reviews.
Mixed: external reviews 4.7/26 positive on service/delivery; Finnrick-tracked with UNEVEN purity (GHK-Cu 89% down to CJC-1295 23%); editorial flags no third-party COAs on products checked; TikTok chatter. Quality concerns temper positive service reviews.

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.
