Research Mechanisms
How Fat Loss Peptides Work
Four primary mechanisms across the most researched metabolic peptide categories.
GLP-1 / GIP Agonism
Tirzepatide and Retatrutide activate GLP-1 and GIP receptors to dramatically reduce appetite and caloric intake.
Enhanced Lipolysis
AOD9604 is a hGH fragment that stimulates fat cell breakdown without anabolic side effects of full GH.
Metabolic Boost
5-Amino-1MQ inhibits NNMT to upregulate NAD+ levels, increasing resting metabolic rate and fat oxidation.
Insulin Sensitization
Multiple compounds in this category improve insulin sensitivity, reducing fat storage and improving glucose utilization.
Spotlight Comparison
Tirzepatide vs Retatrutide
Tirzepatide is a dual GLP-1/GIP agonist with extensive clinical research. Retatrutide adds a third agonism (GCG) for triple-receptor activation — making it one of the most potent metabolic research compounds available. Both are available from Phiogen with ≥99% purity COA.
