Northwest Peptides checkout is designed for research-use acknowledgments and documentation
Formulated for maximum bioavailability at 340 Daltons well below the 500 Da skin penetration threshold so the peptide actually reaches the fibroblast layer where collagen synthesis happens
This is why retatrutide produces greater weight loss even at a lower milligram dose than tirzepatide

Semaglutide (Ozempic, Wegovy): GLP-1 receptor agonist 31-amino acid peptide Position 2: Aib substitution Position 20: Lys acylated with a C18 fatty diacid via a Glu-(AEEA-AEEA) linker Position 28: Arg substitution Tirzepatide (Mounjaro, Zepbound): Dual GIP/GLP-1 receptor agonist 39-amino acid peptide: Position 2 and 13: Aib substitution Position 20: Lys acylated with a C20 fatty diacid via a Glu-(AEEA-AEEA) linker Position 30-39: Amino acid sequence from exenatide Retatrutide: Triple GLP-1/GIP/GCG receptor agonist 39-amino acid peptide: Position 2 and 20: Aib substitution Position 13: Leucine modified with an -methyl group (2-Methylleucine) Position 17: Lys acylated with a C20 fatty diacid via a Glu-(AEEA) linker Position 30-39: Amino acid sequence from exenatide Semaglutide and Tirzepatide are widely available and well-studied, while Retatrutide's long-term effectiveness and safety profile are still being investigated in clinical trials
