Rotate the real, experimentally determined structures of the peptides in our metabolic line, then read the exact amino-acid sequence, molecular weight and engineered modifications for each one. A supplier should be able to show you the molecule, residue by residue.
No experimental structure exists for this peptide. Its amino-acid sequence is shown instead of a modeled fold.
Two vials can both say "retatrutide" on the label and contain different things. The only thing that makes a peptide what it is, is the exact order of its amino acids, the modifications built into that chain, and the purity of what was actually synthesized. A lot of the market cannot tell you any of that. Here is all of it, for every peptide we carry in this line.
The residue order determines the fold, the fold determines which receptor it fits, and that determines what it does. Change one residue and it is a different molecule. We publish the full sequence for each peptide below.
Aib substitutions, a-methyl residues, fatty-acid acylation and C-terminal amides are not impurities. They are engineered in to block enzymes and extend half-life. We label each one and explain why it is there.
Identity is confirmed by mass spectrometry and purity by HPLC on a Certificate of Analysis. A molecular weight is a number you can check the synthesis against. Every figure below is sourced from published characterization.
One-letter amino-acid code. Standard residues in blue; engineered residues and modifications highlighted and explained. Sequences and molecular data are from published characterizations of each compound.
