Retatrutide's mechanism of action centres on its simultaneous activation of GLP-1, GIP, and glucagon receptors
Mechanism of Action 5-Amino-1MQ exerts its metabolic effects primarily through competitive inhibition of nicotinamide N-methyltransferase (NNMT), an enzyme belonging to the methyltransferase superfamily that is expressed in multiple tissues including liver, adipose tissue, skeletal muscle, kidney, and brain, with particularly high expression in visceral (abdominal) adipose tissue - the fat depot most strongly associated with metabolic disease
The fat loss process continues to improve as the peptide takes effect
However, no research directly compares continuous use versus cycling protocols (such as 12 weeks on, 4-8 weeks off), leaving optimal long-term strategies somewhat uncertain
Key Findings from Preclinical Research Insights from Animal Studies While we always look to human trials for definitive answers, preclinical research offers a powerful window into how a compound works
