Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Everest 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 Everest Peptides
Read 5 September 2026 on the vendor's own pages
A real named lab, a real lot number and a measured-mass line on the certificate — the documentation core is sound. What is missing is everything around it: an address, a phone number, a lab-side lookup, and a review base above 45. The stale, contradictory promo banners are cosmetic but they are the vendor's own claims disagreeing with each other.

?Lab-side verification — the certificate is a PDF on the vendor's own server; Freedom Diagnostics has its own site but no lookup we could use.
?Street address or phone — none anywhere on the site; contact is email only.
?Whether 'GLP-2 TRZ' and 'GLP-3 RT' are what the CAS numbers say — the pages print CAS 2023788-19-2 and 2381089-83-2 (tirzepatide and retatrutide) but never use those names.
!Newsletter popup says 'Join 9,000+ researchers, get 20% off' on most pages and 'Join 7,000+ researchers, get 15% off' on the NAD+ page.

Where Everest Peptides ranks by compound
Everest Peptides appears in 13 of our compound rankings, top-3 in 1. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-067/10 — re-issued under rubric v2 (was 5/8); not awarded: review-base, claims-consistent, identity
2026-09-188/10 — review-base awarded — Trustpilot crossed the 50-review threshold (4.8 / 51, read directly 18 Sep 2026); was 7/10
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.
Everest Peptides: the caveat
45 Trustpilot reviews — below our 50 threshold for an independent review base. Certificates are vendor-hosted PDFs, not verifiable at the lab. No street address or phone anywhere on the site. Tirzepatide and retatrutide are sold as 'GLP-2 TRZ' and 'GLP-3 RT' with only a CAS number to identify them. Promotional banners and 'researcher count' claims differ from page to page.

Where the evidence points
Where the evidence points
Purgo Labs 10/10
We earn nothing from Everest Peptides. Purgo Labs holds every rubric point — certificates checkable at the lab, measured net content per lot — and is cheaper after codes on 8 of 9 like-for-like vials.
Purgo Labs, on the evidence: 10/10 rubric points against 8/10. Everest Peptides 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.
Is Everest Peptides legit?
Everest Peptides scores 8/10 on our rubric, has an independently viewable rating of 4.8 (58 reviews), and names its lab (Freedom Diagnostics). Caveat: 45 Trustpilot reviews — below our 50 threshold for an independent review base. Certificates are vendor-hosted PDFs, not verifiable at the lab. No street address or phone anywhere on the site. Tirzepatide and retatrutide are sold as 'GLP-2 TRZ' and 'GLP-3 RT' with only a CAS number to identify them. Promotional banners and 'researcher count' claims differ from page to page.
Which is cheaper, Purgo Labs or Everest Peptides?
On the 9 compound-and-size rows where we have dated prices from both, Everest Peptides lists lower on 7 and Purgo Labs on 2. Purgo's list prices drop 20% with code HEALTH.
Do you earn money from either vendor?
