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.
One Day Compounds sits at 22 out of 60. Middling. Most of the gap is transparency.
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 fine.
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: 11 of 25. They say they provide in-house certificates of analysis. We hold 300 of them; the newest is from Jul 2026. Of the certificates we list, 1 of 2 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 27 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.

very new (~2mo domain); positive Derek Pruski 7/7 vendor + smooth-payment community mention, no documented non-delivery — thin but not scam

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.
