Bottom line
V1 Peptides sells some of the cheapest retatrutide per milligram in this review set. Its testing documentation raises questions, though, and its refund rules are among the strictest we have seen.
Products and pricing
The product is listed as “GLP-3RT”, a “proprietary research peptide”. The product page does not use the name retatrutide, a CAS number or a receptor description. The COA library lists the matching lots as “Retatrutide 10MG/30MG/50MG”. Current sale prices: 10 mg $69.99, 20 mg $109.99, 30 mg $139.99, 50 mg $229.99. All sizes were in stock.
Testing
The COA library names Vanguard Laboratory (A2LA-accredited, ISO 17025) for lots FP25-1022 (10 mg), FP25-1024 (30 mg) and FP25-1026 (50 mg), all reported October 1, 2025. The 10 mg and 30 mg reports show chromatographic purity of >99.80% by HPLC-UV, with measured quantities of 11.13 mg and 33.14 mg. They include no mass-spectrometry identity test and no endotoxin test. Both PDFs were created in Adobe Illustrator in May 2026. Their text layer contains “Pivot Labs LLC” beneath the visible “V1 PEPTIDES LLC” in the “Report To” field. Buyers should confirm any report directly with Vanguard.
