Understanding Half-Life
Half-life (t½) is the time it takes for blood concentration to decrease by 50%. After one half-life, 50% remains. After two half-lives, 25% remains.
Dosing frequency is based on half-life. Short half-life peptides (BPC-157) need daily dosing, while long half-life compounds (Semaglutide) are weekly.
Timing Tips
- • GH peptides: Empty stomach, 2+ hours after eating
- • BPC-157: Flexible timing, consistency matters most
- • GLP-1s: Same day each week, any time
- • Sleep peptides: 30-60 min before bed
- • Nootropics: Morning for best cognitive effects
