Research peptide vendor
A small US research peptide supplier with 17 open-priced listings, some of the lowest per-mg pricing we have recorded, and an unusually detailed account of its testing programme. Its testing lab holds a real ISO/IEC 17025 accreditation we confirmed in the A2LA public directory. No certificate of analysis is published on the site.

$160.00Research use only, stated on the about page, the certificates page and the footer throughout. The disclaimer goes further than most by naming what the business isn't: a chemical supplier, it says, rather than a compounding pharmacy under section 503A of the Federal Food, Drug and Cosmetic Act or an outsourcing facility under 503B. An age gate asks you to confirm you are over 21. No research attestation at checkout.
Graded by whether we could confirm it ourselves or are only repeating what the vendor states. A vendor's honesty about its own testing is a different question from what a published trial shows, so this is a separate scale from the evidence grades on our guides.
They are. All 17 listings show a price and a strength, behind nothing heavier than an age confirmation. Free shipping over $350 is stated in a banner across the top of the site.
Where the vendor states thisThis one checks out. The site names Vanguard Laboratory and cites A2LA certificate 6377.01. A2LA's public customer directory lists that certificate against Olympic Analytical, LLC doing business as Vanguard Laboratory, of Olympia, Washington, accredited to ISO/IEC 17025:2017, scope document dated 22 December 2025. Most peptide vendors cite Janoshik, which holds no such accreditation.
Where the vendor states thisWe couldn't find one. The page titled Chemical Structures and Certificates of Analysis carries three molecular structure diagrams, for BPC-157, GHK-Cu and TB-500, and no certificates at all. The quality assurance page describes what each certificate contains, down to the endotoxin threshold and the signatures on the report. Neither page links to a document, and we found none elsewhere on the site.
Where the vendor states thisThe programme described is HPLC-UV/VIS for purity with assay reported in mg, ICP-MS for arsenic, cadmium, lead and mercury, sterility testing, and the LAL assay for endotoxins under 5.00 EU/mg. That's a fuller panel than most vendors describe, and the detail is specific rather than decorative. With no certificate published, it stays a description of a process rather than a result.
Where the vendor states thisStated explicitly in the footer disclaimer on every page, with the 503A and 503B sections named. Vendors rarely spell this out, and spelling it out removes an ambiguity that some others leave standing.
Where the vendor states thisOn like-for-like strengths it is the cheapest in several places. GHK-Cu 50mg at $30.00 against $44.99 at Olympex Solutions and from $42.95 at Pacific Edge Labs. BPC-157 10mg at $35.00 against $44.95 at Pacific Edge Labs. The KLOW 80mg blend at $100.00 ties Arcane Peptides for the cheapest we have recorded, against $118.95 at Pacific Edge Labs.
Where the vendor states thisThree molecular structure diagrams and a paragraph inviting you to view and verify the certificates, with nothing there to view. Go looking for the evidence the page promises and you come up empty.
The site says testing is moving from Janoshik Analytical to Vanguard Laboratory. Until the changeover completes, a given vial could have been tested by either, and with no published documents there is no way to tell which.
RT-3R, TZ-2T, CGL and TSM are retatrutide, tirzepatide, cagrilintide and tesamorelin. The practice is common in this market and it still means a buyer has to already know what they are ordering.
Finnrick holds no tests for Amino Alchemy, so there is no outside check on the testing programme the site describes.
Buried in the quality assurance page is a note that testing is moving from Janoshik Analytical to Vanguard Laboratory. It reads like housekeeping. It is not.
Janoshik is the default in this market. If you have read a peptide certificate of analysis, it was probably a Janoshik report. The lab is widely used, the reports are recognisable, and vendors cite the name as shorthand for having been tested at all.
What Janoshik doesn't hold is ISO/IEC 17025 accreditation. That standard asks whether an accreditation body has audited the lab's methods, calibration, staff and record-keeping against a published scope, and keeps auditing them.
Vanguard holds it, under A2LA certificate 6377.01, valid through September 2027. We checked that in A2LA's own directory rather than taking the site's word for it.
So a vendor nobody has heard of is moving to a better-accredited lab than the one most of its larger competitors use. That is a real quality decision and it deserves credit.
Which makes the missing documents stranger. The whole point of paying an accredited lab is the paper that comes out of it.
The page is called Chemical Structures and Certificates of Analysis. Its opening line invites you to explore the verified chemical structures and certificates of analysis, tested by accredited third-party laboratories.
What is on it: a structure diagram for BPC-157, one for GHK-Cu and one for TB-500. Molecular drawings, the kind you can pull from PubChem for free in ten seconds.
What is not on it: a certificate. Not a PDF, not an image of a report, not a lot number, not a link out to a lab portal. We checked the page source as well as the rendered page, in case documents were loading late, and there are no document files on it.
This is a pattern we keep meeting and it is worth naming. Inno Peptides has a FAQ entry about its certificates and no certificates. Amino Alchemy has a page named after them, a four-method testing panel described down to the endotoxin threshold, an accredited lab we were able to verify, and still no certificates.
Compare that against Arcane Peptides, which publishes documents by lot and marks which lot is currently shipping, or Olympex Solutions, which prints the measured purity and the lot number on the product card before you add anything to a basket. The difference is not how seriously these vendors describe their testing. It is whether you can read the result.

Don't check out without it. ATLAS10 takes 10% off every Amino Club order, first or repeat. No minimum, no first-order limit.
On what we can verify, yes, with one gap. It's a real shop with open prices, a precise legal disclaimer and a named testing lab whose accreditation we confirmed ourselves. The gap is that no certificate of analysis is published, so the testing programme the site describes in such detail can't be checked against a single result.
Every fact above traces to one of these pages, published by the vendor itself and checked on October 30, 2026. Vendor policy pages change without notice, so if something here looks out of date, it probably is.
