Peptide Half-Life Explained: Why Timing Your Doses Actually Matters

Peptide half-life determines how long a peptide stays active in your body and directly dictates dosing frequency. From BPC-157's 4-hour half-life to semaglutide's 7-day persistence, understanding pharmacokinetics helps optimize results and minimize side effects.

Oral vs Injectable Peptides: Bioavailability and Effectiveness Compared

Injectable peptides deliver 65-100% bioavailability while oral peptides typically achieve under 1-2%, making injection the gold standard for most peptide therapies. Oral semaglutide with SNAC technology is the notable exception, reaching ~1% bioavailability — enough for clinical efficacy at higher doses.
