LY-3437943

Third-party tested · certificate on file · glp-1 and metabolic

A thirty-nine residue triple agonist at the GIP, GLP-1 and glucagon receptors, with aminoisobutyric acid substitutions and a C20 diacid on a lysine. Used to examine how simultaneous engagement of three incretin pathways differs from dual or single receptor agonism in receptor binding and signalling assays.

What the price already covers

  • A certificate of analysis for the exact lot in the box, not a specimen from a previous one.
  • Purity by reversed-phase HPLC and identity by mass spectrometry, on every lot.
  • A second assay at an independent laboratory, drawn from the lot that ships to you, at our cost.
  • Net peptide content measured rather than assumed, so the reconstitution maths is right.
  • The manufacturing facility named on the record, and named again if we stop buying from it.

Free shipping over $99, out the door by 2pm ET, and 60 days to send an unopened vial back for a full refund.
