Bottom line
Full Scale Peptides documents its testing well and spells out its policies clearly. It offers just one vial size, though, and that size was out of stock. The product is “GLP-3R (GLP-3 RT)”, described as a “39-amino-acid triple agonist research peptide targeting the GIP, GLP-1 and glucagon receptors”. Retatrutide is not named.
Products and pricing
10 mg only, at $84.99 ($8.50/mg), marked down from $100. It was out of stock with a notify-me option. A 20% seasonal code was advertised.
Testing
The COA library lists lot FSP-GLP3RT-0626-01, tested by Freedom Diagnostics and reported July 2, 2026 (accession 2606300105). It showed 99.95% purity by HPLC-UV, identity “GLP RT” by LC-MS and 11.38 mg net content. An earlier February 2026 report is also posted. There is no endotoxin or sterility result. The test fields on the product page itself were blank, and the site asks buyers to confirm with support which lot they received.
Shipping and payment
US only. Orders paid by 4 pm ET on weekdays ship the same day by USPS or FedEx. Shipping is a flat $15, or free on orders of $200 and up. Payment methods were not listed on the pages we checked.
Policies and support
“All sales are final.” Damaged, defective, wrong or missing items reported within 7 days, with photos, are replaced or refunded. If tracking shows no movement for 7 business days past the estimate, the company opens a carrier trace and reships or refunds once the loss is confirmed. Purity claims fall under a 14-day limited warranty. Support is by email only, 9 am–6 pm ET, 7 days a week. The operator is Full Scale Peptides LLC, a “Florida-based, family-run” business; no street address or phone number is published.
Reputation
Trustpilot shows 4.4 from 17 reviews (94% five-star). The one 2-star review (June 2026) reported tracking errors and unanswered emails; the company replied, blaming an email outage. The domain was registered in December 2025. We found no FDA warning letter or Eli Lilly lawsuit naming the company.
