Disclosure: Purgo Labs is our affiliate partner, and so is EZ 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 EZ Peptides
Read 6 September 2026 on the vendor's own pages
One of the better certificate chains we have seen — per-vial measured mass and a lab-side verification key — from a company with a name, an address and a phone number, but with no independent review record now that Trustpilot has removed the profile. The house-coded GLP products and the fragment-in-the-TB-500-slot are the things to read twice before ordering.

Could not verify · flags
?Trustpilot profile is REMOVED ('goes against our guidelines', read 5 Sep 2026). The site does not display a Trustpilot badge — it does not misrepresent the removal.
?The Janoshik report at the lab — janoshik.com redirected our requests; the task number on the vendor's page matches the portal link.
?What EZP-1P / EZP-2P / EZP-3P contain from the page itself — no CAS or compound name; older certificate labels on the same pages read 'Semaglutide', 'GLP2TZ' and '3P'.
!The site-wide age gate requires 21+; the Terms state 18+.
!Newer products route 'View Latest Lab Test Result' through a vendor subdomain first rather than straight to Janoshik.
!'TB-500 Frag 17-23' occupies the TB-500 slot in the catalog but is a fragment peptide; the full-length product is listed separately as TB4.
!'Pay with Crypto — Save 10%' on product pages.
!GLP-class products under house codes with no on-page identity.

Where EZ Peptides ranks by compound
EZ Peptides appears in 3 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-068/10 — re-issued under rubric v2 (was 6/8); not awarded: review-base, claims-consistent
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.
EZ Peptides: the caveat
Trustpilot profile REMOVED. Semaglutide, tirzepatide and retatrutide are sold as EZP-1P / EZP-2P / EZP-3P with no stated identity on the page — only older certificate labels reveal it. 'TB-500 Frag 17-23' is a fragment, not full-length TB-500 (a separate TB4 product exists at $68). Age gate says 21+, Terms say 18+. 'Pay with crypto, save 10%'.
07
Where to order
Our pick
Purgo Labs 10/10
Certificates checkable at the lab, measured net content per lot, the deepest GLP-1 catalog we track.
Purgo Labs, on the evidence: 10/10 rubric points against 8/10. EZ Peptides 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 EZ Peptides legit?
EZ Peptides scores 8/10 on our rubric, has no independent record (its Trustpilot profile has been removed), and names its lab (Janoshik Analytical). Caveat: Trustpilot profile REMOVED. Semaglutide, tirzepatide and retatrutide are sold as EZP-1P / EZP-2P / EZP-3P with no stated identity on the page — only older certificate labels reveal it. 'TB-500 Frag 17-23' is a fragment, not full-length TB-500 (a separate TB4 product exists at $68). Age gate says 21+, Terms say 18+. 'Pay with crypto, save 10%'.
Which is cheaper, Purgo Labs or EZ Peptides?
On the 3 compound-and-size rows where we have dated prices from both, EZ Peptides lists lower on 1 and Purgo Labs on 2. Purgo's list prices drop 20% with code HEALTH; EZ Peptides's drop with code compoundreview (10% off).
Do you earn money from either vendor?
