Half-Life
Half-life (t½) is the time required for the plasma concentration of a compound to decrease by half through metabolism and elimination. It is a fundamental pharmacokinetic parameter that influences dosing frequency in research protocols.
Peptide half-lives vary enormously: unmodified small peptides may have half-lives of minutes, while engineered compounds like semaglutide achieve approximately 7-day half-lives through fatty acid albumin-binding modifications. Tesamorelin's N-terminal hexenoic acid modification extends its half-life compared to native GHRH.
