Reconstitution solution

Nexa Labs sells retatrutide as GLP-3 (RT); its product page names retatrutide and gives its CAS number.

While the Halloween sale runs, every vial is 30% off in the cart with no code, and Nexa Labs states that the sale can't be combined with other codes. Two vials of one product take a further 3.6% off that line and three or more 5.3%, and scheduled Subscribe & Save orders take 5% off.

Testing: Labs & Certificates of Analysis

Nexa Labs' certificate library shows one certificate for each of its 11 peptide products, each as an image with its laboratory, lot, date and purity: three from Freedom Diagnostics, three from Krause Analytical (through Finnrick Analytics), four from MZ Biolabs and one from ILS Laboratories. The purities printed run from 99.01% to above 99.9%.

Prof. Peptide found all three Freedom Diagnostics certificates — BPC-157 10 mg, IGF-1 LR3 1 mg and Melanotan II 10 mg — at the laboratory's own document store on October 25, 2026. Each names Nexa Labs as the client and matches the vendor's card on lot, purity and net content. Those three products carry the lab-verified badge in the table below; the badge covers those three certificates, not the rest of the catalog.

The other eight certificates come from ILS Laboratories, Krause Analytical and MZ Biolabs. The four MZ Biolabs certificates carry one lot number, 2025-11-10, and one analysis date; the ILS Laboratories certificate states ISO/IEC 17025.

Prof. Peptide hasn't checked these certificates against the labs' own records.

Nexa Labs is listed on Prof. Peptide's All Vendors page.

All products are sold for laboratory research use only and are not for human or veterinary use.
