Good
NuLab Peptides (American Fork, Utah) sells retatrutide as "GLP3-RT" in 10mg, 20mg, 30mg and 40mg vials plus 10-vial kits, shipping within the US. One retatrutide lab report (30mg, Freedom Diagnostics, May 2026) is published and confirmed on the lab's server; reports for the other strengths are listed as coming soon.
Worth knowing (not scored)

- COA library lists GLP3-RT 10mg, 20mg and 40mg reports as 'coming soon / pending'; only the 30mg lot R0526C has a report.

- Catalogue includes oxytocin, kisspeptin and PT-141 peptides; no steroids, SARMs, HGH or HCG seen.
- Product pages show a 'confirm you are human' check to headless browsers; plain HTTP and the Store API work.
