Pharmacodynamic Effects and Duration Despite measurable plasma clearance, pharmacodynamic effects extend well beyond plasma half-life[20]: Weight loss effects continue throughout treatment with no plateau observed within 48-week study periods Glycemic improvements persist between weekly doses with stable glucose control Appetite suppression effects remain consistent throughout dosing intervals Tissue receptor occupancy likely exceeds plasma peptide concentrations This disconnect between pharmacokinetics and pharmacodynamics suggests prolonged receptor engagement, tissue depot effects, or persistent downstream signaling cascade activation

However, chronic use or high doses may require a longer recovery period and more focused nutritional support
in Germany reported the efficacy and safety of a hydrolyzed collagen peptide (HCP) supplement (a commercial product called Colla Sel Pro) in improving skin health in adult female individuals in a double-blind, randomized, placebo-controlled trial using biophysical (Callegari Soft-Plus device) and skin imaging (3D) techniques [48]
