retatrutide
newRetatrutide (LY3437943) is a synthetic 39-amino-acid peptide — a single-chain, lipidated analog engineered on a glucose-dependent insulinotropic polypeptide (GIP) backbone that engages the GLP-1, GIP and glucagon receptors, incorporating 2-aminoisobutyric-acid substitutions, an α-methyl-leucine residue, a C20 fatty-diacid moiety conjugated at a lysine, and a C-terminal amide. In published preclinical and clinical literature it has been investigated as a candidate molecule in metabolic-regulation and body-weight research. Supplied lyophilized at ≥99% HPLC purity with a per-lot Certificate of Analysis. For laboratory and research use only — not for human or animal consumption. ROEHN makes no claims regarding its effects.
A single-molecule tri-agonist peptide investigated in METABOLIC-REGULATION research.

Very good. Great products. Turnaround time was just a tad slow.
