Verdict: Purgo Labs, on the evidence: 10/10 rubric points against 4/10. SKO Compounds is stronger on 4 points listed below.
Disclosure: Purgo Labs is our affiliate partner, and so is SKO Compounds. Scores are produced by the published rubric, which has no partnership input.
One point each, no weighting. The evidence text is what we read and when.
No compound-and-size pair with dated prices from both vendors yet. Each vendor's readings are on the Peptide Price Index.
Read on 24 September 2026 on the vendor's own pages and the independent platforms linked. These are the findings behind the 4/10 above — not a summary of the vendor's marketing.
A large, active review base and, as of this read, a company name — but not one certificate we could open, and no lab named. The score is low because the documentation is, not because of the reviews. Affiliate partner; disclosed, not scored.

Every re-verification is dated and kept; a score only changes when the evidence does.
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
The testing laboratory is not named anywhere we could find, so testing claims cannot be looked up. Pre-order 'Research Sprays' displayed star ratings and review counts before their stated ship date — reviews cannot precede shipment, and on-site review counts are self-hosted and unverifiable. Roughly 15 of ~34 vial products were sold out on the day checked.

Visit SKO CompoundsContext from our hand-written research that the numbers above cannot carry — brand confusion, catalog risk, testing specifics. Nothing here changes the score.
On the day we checked, SKO listed five pre-order spray products with a stated ship date of 22 August 2026 - each already displaying a star rating and review count, such as 4.9 from 186 reviews. Reviews cannot precede shipment. We offer no theory about the numbers' origin; the observation was checkable on their homepage, and its practical meaning is that SKO's self-hosted ratings should not inform a buying decision. Its independently hosted Trustpilot record is a separate matter and remains genuine.
Purgo Labs, on the evidence: 10/10 rubric points against 4/10. SKO Compounds is stronger on 4 points listed below. Every point is a fact you can check on either vendor's site; both are scored by the same published rubric.
SKO Compounds scores 4/10 on our rubric, has an independently viewable rating of 4.8 (535 reviews), and does not name its testing laboratory. Caveat: The testing laboratory is not named anywhere we could find, so testing claims cannot be looked up. Pre-order 'Research Sprays' displayed star ratings and review counts before their stated ship date — reviews cannot precede shipment, and on-site review counts are self-hosted and unverifiable. Roughly 15 of ~34 vial products were sold out on the day checked.
We do not yet have a like-for-like price pair for these two vendors; the Peptide Price Index has each vendor's dated readings.
