Personalized GLP-1 Selection with Genetic Testing The PlexusDx Precision Peptide Genetic Test analyzes GLP1R (rs6923761), GIPR (rs1800437), FTO (rs9939609), and MC4R (rs17782313) variants that relate to GLP-1 and related signaling pathways
Despite the great interest in this topic, few studies have sufficiently contextualized the loss of lean tissue induced by semaglutide, the authors write
This correlates more strongly with metabolic health improvements than body weight
Milligrams per tirzepatide dosages, for example, are significantly higher
One consistent finding is that peak tissue changes often lag weight loss, with maximal soft-tissue sagging commonly observed 6 to 12 months post-initial weight loss, aligning with clinical guidance that peak GLP-1 weight loss occurs at about 52 weeks
