Read on 24 September 2026 on the vendor's own pages and the independent platforms linked. These are the findings behind the 7/10 above — not a summary of the vendor's marketing.
A lab-verifiable certificate from a vendor that cannot say where it ships from, has no address, and has lost its Trustpilot profile. Not an affiliate partner.

Each row is a certificate we opened and read ourselves; "verify at the lab" goes to the laboratory's own lookup, never a copy we host. Full COA library →
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.
No independently viewable Trustpilot review record; the domain currently resolves to Trustpilot's removed-profile template, but its prior profile state is uncertain. Pricing is shown as 'from' without sizes on most items.
Context from our hand-written research that the numbers above cannot carry — brand confusion, catalog risk, testing specifics. Nothing here changes the score.
Chromate (chromate.org), named on the COA portal as the exclusive testing partner — and naming the lab puts Disguised Alpha ahead of vendors that say only "third-party tested". Two caveats. Disguised Alpha describes Chromate as ISO 17025 accredited, but Chromate's own website does not state that accreditation anywhere we could find. And the homepage separately claims verification by "the 3 most trusted labs" while the COA portal says testing runs exclusively through Chromate — those statements cannot both be right as written.
Breadth. Alongside peptides it sells SARMs and research chemicals — YK-11, Cardarine, MK-677, SR-9009, Phenibut, RU58841 and others — plus capsule and aerosol formats. That is a different risk category from a peptide-only catalog: SARMs are the product class at the centre of the 2026 Paradigm Peptides federal case, where products sold as SARMs were found to contain testosterone. We are not suggesting Disguised Alpha mislabels anything — its stated 8-panel testing addresses exactly this — but a reader comparing vendors should know the catalogs are not the same kind of catalog.
Purgo Labs, on verifiability: named laboratories whose results are hosted and checkable at the lab itself, an independent 80-review Trustpilot record, no contradictions between its claims, and a 20% code (HEALTH) that applies to every order rather than 10% on the first. Disguised Alpha's certificate breadth and 8-panel testing claim are genuinely impressive, and if its review base and lab-accreditation claims firm up, this comparison gets closer. Disclosure: we earn a commission on Purgo Labs links and nothing from Disguised Alpha.
Purgo Labs, on the evidence: 10/10 rubric points against 7/10. Disguised Alpha 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.
Disguised Alpha scores 7/10 on our rubric, has no independently viewable review record, and names its lab (Chromate). Caveat: No independently viewable Trustpilot review record; the domain currently resolves to Trustpilot's removed-profile template, but its prior profile state is uncertain. Pricing is shown as 'from' without sizes on most items.
On the 14 compound-and-size rows where we have dated prices from both, Disguised Alpha lists lower on 2 and Purgo Labs on 9 (3 equal). Purgo's list prices drop 20% with code HEALTH.
