Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Ascension Peptides. 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 Ascension Peptides
Read 11 September 2026 on the vendor's own pages
Better testing paperwork than most of this batch — a named laboratory with batch-level certificates on every product — sitting next to a Trustpilot profile that Trustpilot itself has taken down. Until that is explained and a legal entity is published, the documentation points and the conduct flag cancel each other out.

Could not verify · flags
?Certificates are vendor-hosted PDFs; we found no link to Kovera's verification portal, so the reports could not be checked at the laboratory.
?Net content against the label — the certificate PDF was not opened.
?A legal entity — the Terms and Refund pages name none, and the address is a Unit number.
!Trustpilot has removed the vendor's profile: 'The business you're trying to find goes against our guidelines and is no longer visible' (read 11 Sep 2026).
!Every price is displayed as a permanent sale against a struck-through list price.

This certificate does not state measured net content — purity alone does not tell you how much is in the vial, which is why the rubric scores them separately.

Where Ascension Peptides ranks by compound
Ascension Peptides appears in 7 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-115/10 — first assessment (rubric v2); not awarded: lab-hosted, net-content, review-base (Trustpilot profile removed), clean-record, identity
Purgo Labs: the caveat
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.
Ascension Peptides: the caveat
Trustpilot has removed the profile ('goes against our guidelines'), so there is no independent review record and the removal itself is a conduct flag. Certificates are vendor-hosted PDFs, not lab-portal links. The only address is a Unit # in Kansas City with no legal entity named on Terms or Refund pages. Every price is shown as a permanent sale against a struck-through list price.

Where the evidence points
Where the evidence points
Purgo Labs 10/10
We earn nothing from Ascension Peptides. Purgo Labs holds every rubric point — certificates checkable at the lab, measured net content per lot — and is cheaper after codes on 4 of 4 like-for-like vials.
Purgo Labs, on the evidence: 10/10 rubric points against 5/10. Ascension Peptides is stronger on 2 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 Ascension Peptides legit?
Ascension Peptides scores 5/10 on our rubric, has no independent record (its Trustpilot profile has been removed), and names its lab (Kovera Labs · MZ Biolabs). Caveat: Trustpilot has removed the profile ('goes against our guidelines'), so there is no independent review record and the removal itself is a conduct flag. Certificates are vendor-hosted PDFs, not lab-portal links. The only address is a Unit # in Kansas City with no legal entity named on Terms or Refund pages. Every price is shown as a permanent sale against a struck-through list price.
Which is cheaper, Purgo Labs or Ascension Peptides?
On the 4 compound-and-size rows where we have dated prices from both, Ascension Peptides lists lower on 0 and Purgo Labs on 4. Purgo's list prices drop 20% with code HEALTH.
Do you earn money from either vendor?
