Disclosure: Purgo Labs is our affiliate partner; we earn nothing from AIO 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 AIO Peptides
Read 1 October 2026 on the vendor's own pages
Behind the login the paperwork is better than the public face suggests: a Freedom Diagnostics report the lab's own lookup confirms, a lot code on 38 batches, measured content above label, sized prices. What it still will not show is who it is — no company name, a terms page with a '[Jurisdiction]' placeholder, and a review profile that is gone. 6/10 read through an account; a buyer who has not registered can still verify nothing, which is why ungated stays withheld. If AIO opened the certificates and catalog to the public and named its entity, it would score 8.

?Anything from outside a login — the homepage, /shop/, /coa/, /about-us/ and /contact-us/ still redirect to /my-accounts/ for a logged-out visitor (1 Oct 2026). The certificates are real, but a buyer cannot see them, or a price, before registering.
?A legal entity or street address — the about page says 'founded in 2024'; the terms page reads 'governed by … the laws of [Jurisdiction]', an unfilled template; contact is hello@aiopeptides.com and 469-880-0955 only.
?Any independent review record — the Trustpilot profile for www.aiopeptides.com has been removed (re-checked 1 Oct 2026).
?The in-house synthesis described on the quality-control page ('peptides are synthesized using advanced equipment … in-process controls … multiple purification steps') — no facility, location or company is named anywhere on the site, so the claim cannot be checked.
?Payment rails — the checkout page redirects to an empty cart and we did not place an item in a live account's cart. Zelle and ACH are promoted with an extra 5% off.
!The COA page says every batch is tested 'using industry-leading UPLC / MS technology'; the certificate's own method line reads 'HPLC with UV Detection Coupled with Mass Spectrometry'. Minor, but the two statements are the vendor's and the lab's, and they differ.
!LOOKALIKE DOMAIN. aiopeptidesusa.com (registered 18 April 2026, thirteen months after aiopeptides.com) sells under the AIO Peptides name with keyword-stuffed copy, no about or terms page, no certificate anywhere, and a 15% discount for paying to a Bitcoin wallet printed on the product page. AIO's own site says aiopeptides.com is its only domain. Check the address bar before paying.
!Login wall on every page — the single largest deduction.
!No legal entity; the terms are an unfilled template.
!Trustpilot profile removed.
!All sales final: no returns, refunds, modifications or cancellations once an order is placed.
!GLP-class compounds sold under codes (GLP1-S, GLP2-T, GLP3-R) as research material.
No legal entity. Terms print 'laws of [Jurisdiction]' as a placeholder; hello@aiopeptides.com · 469-880-0955 (1 Oct 2026).

Where AIO Peptides ranks by compound
AIO Peptides appears in 4 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.
2026-09-280/10 — first assessment (rubric v2); nothing awarded — entire storefront (shop, product, quality-control, about, contact) redirects to a login form logged out; Trustpilot profile removed
2026-10-016/10 — 0/10 → 6/10, read through a registered account (LuvionBio / Petratide precedent): Freedom Diagnostics report found on the lab's own lookup, 38 lots on the COA page, 10.32mg on a 10mg label, sized prices. Still withheld: ungated (login wall), identity (no legal entity — terms print '[Jurisdiction]'), review-base (Trustpilot removed), claims-consistent (unevidenced in-house synthesis claim; UPLC vs HPLC)
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.
AIO Peptides: the caveat
No legal entity anywhere: the terms page still reads 'governed by the laws of [Jurisdiction]' — a template placeholder — and the only contact is hello@aiopeptides.com and a Texas-area phone number. Trustpilot profile REMOVED. Login wall on every page. All sales final. Zelle or ACH earn an extra 5%; we did not examine the card rail. aiopeptidesusa.com is a lookalike (registered 18 Apr 2026, crypto wallet printed on the product page, no certificates) — AIO's own site names aiopeptides.com as its only domain.

Where the evidence points
Where the evidence points
Purgo Labs 10/10
We earn nothing from AIO Peptides. Purgo Labs holds every rubric point — certificates checkable at the lab, measured net content per lot — and is cheaper after codes on 3 of 3 like-for-like vials.
Purgo Labs, on the evidence: 10/10 rubric points against 6/10. AIO 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 AIO Peptides legit?
AIO Peptides scores 6/10 on our rubric, has no independent record (its Trustpilot profile has been removed), and names its lab (Freedom Diagnostics). Caveat: No legal entity anywhere: the terms page still reads 'governed by the laws of [Jurisdiction]' — a template placeholder — and the only contact is hello@aiopeptides.com and a Texas-area phone number. Trustpilot profile REMOVED. Login wall on every page. All sales final. Zelle or ACH earn an extra 5%; we did not examine the card rail. aiopeptidesusa.com is a lookalike (registered 18 Apr 2026, crypto wallet printed on the product page, no certificates) — AIO's own site names aiopeptides.com as its only domain.
Which is cheaper, Purgo Labs or AIO Peptides?
On the 3 compound-and-size rows where we have dated prices from both, AIO Peptides lists lower on 2 and Purgo Labs on 1. 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 AIO Peptides. Scores come from the rubric, which has no partnership input, and the ordering rule on our scoreboard is disclosed.
