Level Up sells retatrutide as LU-RT3 and tirzepatide as LU-TZ2, and its own certificates name each: the ILS Laboratories reports for LU-RT3 10mg, 20mg and 30mg confirm Retatrutide as the identity, and the ILS report for LU-TZ2 20mg confirms Tirzepatide. MTP-31 is SS-31: Freedom Diagnostics' certificate Leve2608180179, issued to Level Up Peptides for MTP-31 50mg, reports its identity by LC-MS as SS-31. Level Up sells semaglutide as LU-SG1, a mapping confirmed to Prof. Peptide first-hand.

Testing: Labs & Certificates of Analysis

Level Up's certificate library lists one report per product and strength, from Freedom Diagnostics, ILS Laboratories and Vanguard Laboratory. The Freedom Diagnostics reports cover purity by HPLC-UV, identity by LC-MS and net content, then elemental impurities by ICP-MS, bacterial endotoxin to USP <85> and a PCR microbial screen. The ILS reports cover purity by HPLC, identity against a reference standard, net peptide content, heavy metals by ICP-MS, sterility by PCR, a fentanyl immunoassay screen and endotoxin. Level Up states that every batch is tested at an independent laboratory before it ships.

Prof. Peptide matched two of its certificates at Freedom Diagnostics' own document store on October 18, 2026: Kisspeptin 10mg (99.04%) and KPV 10mg (99.57%), each naming Level Up Peptides as the client. The access code printed on the ILS certificate for LU-RT3 10mg, JCR63Q8Z, returned the matching certificate at ILS Laboratories' own verification form when Prof. Peptide entered it on September 21, 2026. The panel below lists every certificate's own results.
