Bottom line
Peptide Foundry pairs strong, current testing with strong shipping terms. It is expensive, and it has no review history to judge it by. The product is called “GLP-3” and described as “a synthetic triple-agonist peptide developed as a GLP-1/GIP/glucagon receptor research compound”, with CAS 2381089-83-2. Retatrutide is not named.
Products and pricing
10 mg $100 ($10.00/mg) and 20 mg $185 ($9.25/mg), both in stock. An optional $50/month membership advertises about 23% off. A “Build Three” bundle offers 20% off plus free bacteriostatic water.
Testing
The 10 mg lot FO777 was tested by Freedom Diagnostics on September 6, 2026. It showed 99.98% purity by HPLC-UV, identity confirmed by LC-MS and 11.11 mg net content. Heavy metals, microbial PCR and endotoxin (USP <85>) all passed, and the report has a verification access code. The 20 mg lot FO772 is listed at 99.98%. The FAQ names ILS Laboratories, Freedom Diagnostics and Chromate as its testing labs.

Reputation
The Trustpilot profile was claimed in September 2026 and has no reviews. The domain was first registered in February 2020 and last updated in December 2025. We found no FDA warning letter or Eli Lilly lawsuit naming the company. Not to be confused with The Peptide Foundry (thepeptidefoundry.com).
