Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Peptira. 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 Peptira
Read 19 September 2026 on the vendor's own pages
One of the cleanest certificate chains we have opened this month — lab named, lot number, three measured vials, and the report served from the lab's own domain by code. What is missing is everything that lets you find the company: the review profile is gone and the only address is a PO box.

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 Peptira ranks by compound
Peptira appears in 4 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-198/10 — first assessment (rubric v2); not awarded: review-base (Trustpilot removed), identity (P.O. Box only)
2026-10-027/10 — 8/10 → 7/10: ungated withdrawn — the storefront, product pages and lab-results page now redirect to a sign-in gate (read 2 Oct 2026); the COA library remains public
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.
Peptira: the caveat
LOGIN WALL since late September: as of 2 Oct 2026 the homepage, catalog, product pages and lab-results page redirect to a sign-in gate ('Research accounts only'); only the COA library is public, so prices and the catalog can no longer be checked before registering. Trustpilot profile REMOVED (read 19 Sep 2026; a third-party read on 18 Sep showed 4.5 across 244 reviews, so the removal is recent). Legal entity is Peptira LLC but the only address published is a P.O. Box (Chadron, NE 69337) — no street address. The 61-peptide catalog sits beside pressed raws and 'other' categories; check what you are buying.

Where the evidence points
Where the evidence points
Purgo Labs 10/10
We earn nothing from Peptira. 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 7/10. Peptira 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 Peptira legit?
Peptira scores 7/10 on our rubric, has no independent record (its Trustpilot profile has been removed), and names its lab (Freedom Diagnostics). Caveat: LOGIN WALL since late September: as of 2 Oct 2026 the homepage, catalog, product pages and lab-results page redirect to a sign-in gate ('Research accounts only'); only the COA library is public, so prices and the catalog can no longer be checked before registering.

Which is cheaper, Purgo Labs or Peptira?
On the 4 compound-and-size rows where we have dated prices from both, Peptira lists lower on 2 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 Peptira. Scores come from the rubric, which has no partnership input, and the ordering rule on our scoreboard is disclosed.
