Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Oneday Compounds. Scores come from the public rubric, which has no partnership input.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.

What we found at Oneday Compounds
Read 29 October 2026 on the vendor's own pages
The certificates are among the better ones we read: lab-hosted, lot-numbered, three vials per batch, and the content is on label. The company names itself and gives an Ogden street address. Cards are taken at checkout. What holds it at eight: you cannot see a price or a certificate without an account, and the testing claim changes from 16 to 12 points on the same page.

VerifiedTrustpilot 4.8 across 88 reviews on a claimed profile
(claimed March 2026, paid subscription): 96% five-star, 3% four-star, 1% one-star; the vendor invites every customer to review and has replied to every negative review.
Contradiction — the vendor's claims disagree with each other or with the evidence
ContradictionThe BPC-157 product page's trust strip says 'Up to 16X testing by an ISO/IEC 17025-accredited laboratory' while the same page's description and the testing page say 'Up to 12-Point Analytical Verification'. Two different counts for the same programme on one page (29 Oct 2026).
checkout offers Visa, American Express, Apple Pay / Google Pay, other credit cards, same-day bank payment and Zelle (5% off for Zelle); the FAQ still lists only Zelle, Cash App, Venmo and ACH. All sales are final; damage must be reported within 24 hours of delivery with photos.
the banner says Oneday Compounds is 'gradually becoming BY ONEDAY', with 40% off sitewide and up to 15% more for bulk.

FlagTrustpilot invites every customer to review, which tends to lift scores
one recent five-star review describes personal weight loss, which the vendor did not answer or correct.

Could not verify — not on the record either way
Could not verifyThe 'up to 12 points' panel on every lot
the retatrutide report we opened carries purity, identity, net content, three-vial conformity, sterility, endotoxin, heavy metals and a fentanyl screen; residual solvents, container-closure integrity and solubility were not on it. The testing page says earlier batches may have a different panel.

Could not verifyThe GLP-class products sold as OC-2TZ
we did not open a tirzepatide report, so their identity is the vendor's word on this read.

Check it yourself: Certificates print an ILS access code (e.g. NZHW9KJZ on COA-2026-Y_PBKT); enter it on the lab's site to pull the same report. The button above opens the lab's lookup.
Three vials tested (10.22 / 10.31 / 10.59 mg); sterility no growth, endotoxin 0.027 EU/mL, heavy metals pass, fentanyl screen negative. Sold by code as OC-3RT; the lab confirms retatrutide.
Where Oneday Compounds ranks by compound
Oneday Compounds appears in 20 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
29 Oct 20268/10 — first assessment (rubric v2), read through a registered account: ILS Laboratories reports on the lab's own portal, 10.31 mg on a 10 mg retatrutide label (three vials), 57 lot-numbered COA entries, Oneday Enterprises LLC with an Ogden street address, 4.8 / 88 Trustpilot; cards at checkout (Zelle optional, 5% off); not awarded: ungated (login wall), claims-consistent (16X vs 12-point testing claims)
Purgo Labs: the caveat
Smaller independent review base than several competitors (101 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
Oneday Compounds: the caveat
Prices and certificates need an account (the ungated deduction). All sales are final, with damage to be reported within 24 hours; checkout takes cards, but Zelle carries a 5% discount and the FAQ still lists only Zelle, Cash App, Venmo and ACH. The same product page promises 'Up to 16X testing' in its trust strip and 'Up to 12-Point Analytical Verification' in its description (the testing page also says 12), which is the claims-consistent deduction. GLP-class products are sold by code (OC-2TZ, OC-3RT); the lab confirms retatrutide for OC-3RT.

Where the evidence points
Where the evidence points
Purgo Labs 10/10
We earn nothing from Oneday Compounds. Purgo Labs holds every rubric point — certificates checkable at the lab, measured net content per lot — and is cheaper after codes on 1 of 21 like-for-like vials.
Purgo Labs, on the evidence: 10/10 rubric points against 8/10. Oneday Compounds is stronger on 3 points listed below. Every point is a fact you can check on either vendor's site; both are scored by the same published rubric.
Is Oneday Compounds legit?
Oneday Compounds scores 8/10 on our rubric, has an independently viewable rating of 4.8 (88 reviews), and names its lab (ILS Laboratories (San Diego, CA)). Caveat: Prices and certificates need an account (the ungated deduction). All sales are final, with damage to be reported within 24 hours; checkout takes cards, but Zelle carries a 5% discount and the FAQ still lists only Zelle, Cash App, Venmo and ACH. The same product page promises 'Up to 16X testing' in its trust strip and 'Up to 12-Point Analytical Verification' in its description (the testing page also says 12), which is the claims-consistent deduction. GLP-class products are sold by code (OC-2TZ, OC-3RT); the lab confirms retatrutide for OC-3RT.
Which is cheaper, Purgo Labs or Oneday Compounds?
On the 21 compound-and-size rows where we have dated prices from both, Oneday Compounds lists lower on 21 and Purgo Labs on 0. Purgo's list prices drop 20% with code HEALTH.
Do you earn money from either vendor?
Purgo Labs is our affiliate partner and we earn a commission on referred orders; we earn nothing from Oneday Compounds. Scores come from the rubric, which has no partnership input, and the ordering rule on our scoreboard is disclosed.
