Within weeks, most people notice brighter tone, softer texture, and firmer contours

In vitro studies on bone cells supported the expression of the conventional GLP-1R in osteoblasts and confirmed that liraglutide, at nanomolar concentrations, promoted osteoblast differentiation and reduced osteoblast apoptosis via activation of the PI3K/Akt/GSK3K, MAPK, and cAMP/PKA/-catenin intracellular pathways [46,47,48]
This means that a peptide with a 2-hour half-life administered three times daily will reach steady-state within approximately 10 hours, while a peptide with a 7-day half-life like Semaglutide requires roughly 35 days to reach steady state with weekly dosing
