Bottom line
NuLab Peptides has friendlier return terms than most stores and a published address, but it charges more than most and has lab reports for only one retatrutide size.
Products and pricing
The product is sold as “GLP3-RT” and described as a “Research Metabolic Pathway Compound”. The page gives no compound name, CAS number or mechanism. The COA library’s report for the 30 mg size names the sample “Retatrutide 30mg”. Prices: 10 mg $117, 20 mg $145.80, 30 mg $182.70 and 40 mg $206.10, all in stock. 10-vial kits are also sold (10 × 10 mg $1,167.30).
Testing
Freedom Diagnostics tested 30 mg lot R0526C at 99.89% by HPLC, with 35.12 mg measured and LC-MS identity listed as “GLP RT” (reported May 11, 2026). A separate endotoxin report on the same lot passed. The COA library marks the 10, 20 and 40 mg reports as “coming soon”, and the product page does not show a COA.
Shipping and payment
Orders ship within 48 business hours, and the site says they “almost always ship the same day—even on weekends”. Shipping is free over $149. PO boxes go by USPS, and other orders go by FedEx or UPS. We found no rates for smaller orders and no ship-from location. A $5 reship fee applies to orders returned because of a customer address error. The terms say payment may include credit and debit cards, eCheck, cryptocurrency and digital wallets.
Policies and support
Sales are described as generally final once processed. However, the policy page accepts return or exchange requests for unopened, unused items within 14 days of delivery. The buyer pays return shipping, and refunds are issued as store credit, with a restocking fee of up to 15%. Support is by email ([email protected]) and contact form; we found no phone number. The address is 735 S Auto Mall Dr, Suite 200, American Fork, UT 84003, and Utah law governs the terms.
Reputation
The domain was registered April 4, 2026. Trustpilot shows 4.1 from 5 reviews, all five-star, on a profile claimed in June 2026. We found no FDA warning letter or Eli Lilly lawsuit naming the company.
