Good
Peptide Foundry LLC sells retatrutide under the code name 'GLP-3' in 10mg and 20mg vials, with free UPS shipping inside the US only. The 10mg lot has a Freedom Diagnostics report (tested September 6, 2026) that names the sample 'Retatrutide 10mg' and matched the lab's own lookup.
Worth knowing (not scored)
- Entity named on the site, but no matching registry record found
- The product is sold as 'GLP-3'. The product page lists CAS 2381089-83-2 (retatrutide) and calls it a GLP-1/GIP/glucagon triple agonist, and the lab report names the sample 'Retatrutide 10mg'.
- Freedom Diagnostics lookup with access code Pept2609040443 returned a PDF identical to the one on the shop site (client 'Peptide Foundry', lot FO777, received 9/4/2026, reported 9/6/2026). The report also covers identity, heavy metals, endotoxin and microbial tests.
- Only a 10mg report is posted; no separate report for the 20mg vial was found.
- Trustpilot profile is claimed (September 2026) but has 0 reviews.
- Catalogue includes tesamorelin, sermorelin, PT-141, melanotan 2 and IGF-1 LR3, but no steroids, SARMs, HGH, HCG or testosterone were found.
Points in its favor
- Named legal entity (Peptide Foundry LLC, Delaware) and a street address
- Recent lab report that names retatrutide and matched the lab's lookup
- Free UPS shipping with about 2-day delivery and free shipment protection
- No dosing content found
Points against
- Only two strengths (10mg and 20mg)
- No lab report posted for the 20mg vial
- Card only, and Mastercard is not accepted
- No Trustpilot reviews yet
