Just want to know whether it is safe to order from? The trust checks — company identity, lab lookup, payment rail, what we flagged — are on Is Oneday Compounds legit?
The testing is the best part, and it holds up at the lab. Oneday's COA library has 57 entries, every one with a lot number, and the links open on ILS Laboratories' own portal rather than a file on the vendor's server. We opened the retatrutide report (sold as "OC-3RT" 10 mg, lot OC-RT10-106, analysed 2 September 2026): identity retatrutide confirmed, purity 99.63%, 10.31 mg measured on a 10 mg label, and three separate vials at 10.22, 10.31 and 10.59 mg, with sterility, endotoxin and heavy metals passed. The BPC-157 10 mg page prints its shipping lot, OC-BPC10-104, at 99.82% and 10.30 mg. The company names itself (Oneday Enterprises, LLC) and gives a street address in Ogden, Utah, and the Trustpilot record is 4.8 across 88 reviews.
Two things keep it at eight. You need an account to see a single price or certificate. And the same product page promises "up to 16X testing" in one block and "up to 12-point" verification in the next; the report we opened carried eight of the twelve panels listed. Checkout takes Visa, American Express, Apple Pay and Google Pay alongside bank payment and Zelle (Zelle gets 5% off), so a card with a dispute route is there if you want it; all sales are final.
Prices are low right now because the store is rebranding to "BY ONEDAY" with 40% off everything (BPC-157 10 mg $23.99 from $39.99), so check whether the price still holds when you order. Eight of ten, read 29 October 2026. Oneday is not an affiliate partner of ours.
