Half-life

Last updated

How long it takes for half of a peptide to clear from the body. A short half-life may mean more frequent dosing; a long one may allow less frequent dosing.

Half-life is one of the main reasons two peptides with similar effects can call for very different schedules: a short half-life may point toward daily or twice-daily injections, while a long one can stretch dosing to weekly. It does not change how a vial is reconstituted, but it heavily influences how quickly that vial is used up and how frequently the calculator's per-dose figures are applied.
