What we found at Premier Bio Labs
Read 1 November 2026 on the vendor's own pages
Three things to keep in mind. GLP-class products are sold under codes (PBL-SM1, PBL-TZ2, PBL-RT3), and the ILS report names the sample only as 'PBL-R3', so the lab confirms the vendor's reference rather than naming the compound. Some 'regular' prices are far above the sale price (BPC-157 10 mg $19 against $50.99), which is an anchor rather than a real discount. And the two Wyoming addresses in its materials are both registered-agent addresses. Ten of ten on the same rubric as Purgo Labs, our affiliate partner; the score does not read partnership..

Flag — read before ordering
FlagTwo Wyoming addresses appear
Cheyenne on the contact page and 30 N Gould St, Sheridan in the terms; both are common registered-agent addresses. GLP-class products are sold as PBL-SM1, PBL-TZ2 and PBL-RT3, and the ILS report we opened names the compound only as 'PBL-R3', so the lab does not confirm which GLP compound it is. Several 'regular' prices are more than 2.5 times the sale price (BPC-157 10mg $19 against $50.99), which reads as an anchor rather than a real former price. The site footer says it is powered by Sterling Path LLC. The domain was registered in September 2025, and Trustpilot notes the company has not replied to negative reviews.

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.
Served from ILS's own file server, tested for PremierBioLabs LLC. The report names the sample 'PBL-R3'; identity is confirmed against the vendor's reference for PBL-R3, so the lab does not itself name retatrutide.
Where Premier Bio Labs ranks by compound
Premier Bio Labs appears in 10 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
1 Nov 202610/10 — first assessment (rubric v2); not awarded: none — every criterion carries a dated source
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.

Where the evidence points
Where the evidence points
Purgo Labs 10/10
We earn nothing from Premier Bio Labs. Purgo Labs holds every rubric point — certificates checkable at the lab, measured net content per lot — and is cheaper after codes on 3 of 14 like-for-like vials.
A tie on evidence — both earn 10/10. What separates them is review base (4.7 (69 reviews) vs 4.8 (101 reviews)) and price (12 rows cheaper at Premier Bio Labs, 2 at Purgo). Every point is a fact you can check on either vendor's site; both are scored by the same published rubric.
Is Premier Bio Labs legit?
Premier Bio Labs scores 10/10 on our rubric, has an independently viewable rating of 4.7 (69 reviews), and names its lab (ILS Laboratories + Freedom Diagnostics). Caveat: Two Wyoming addresses appear: Cheyenne on the contact page and 30 N Gould St, Sheridan in the terms; both are common registered-agent addresses. GLP-class products are sold as PBL-SM1, PBL-TZ2 and PBL-RT3, and the ILS report we opened names the compound only as 'PBL-R3', so the lab does not confirm which GLP compound it is.

Which is cheaper, Purgo Labs or Premier Bio Labs?
On the 14 compound-and-size rows where we have dated prices from both, Premier Bio Labs lists lower on 12 and Purgo Labs on 2. 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 Premier Bio Labs. Scores come from the rubric, which has no partnership input, and the ordering rule on our scoreboard is disclosed.
