TB-500 half-life calculator
TB-500 is a systemic recovery peptide, often run on a loading/maintenance cycle. Its elimination half-life is about 2.5 days — so a dose largely clears in roughly 13 days. See how it rises as it absorbs, peaks, and falls below.

Solid = while you're dosing; dashed = projected clearance after the last dose. The curve rises as each dose absorbs, then falls — and climbs over the first several doses until it settles into a steady peak-and-trough.
How long does TB-500 stay in your system?
A compound is considered essentially cleared after about five half-lives. With TB-500's half-life of about 2.5 days, that's roughly 13 daysafter your last dose. The calculator's dashed line shows that clearance tail.
TB-500 steady state & accumulation
Dosed twice weekly, each TB-500 dose is given before the previous one fully clears, so levels climb over the first several doses and settle into a steady peak-and-trough pattern in about 13 days — building to about 1.61× a single dose. That accumulation is why the early period can feel different from later on, and why a gradual titrationgives your body time to adjust.
Half-life figures for TB-500 are approximate — reported values vary and absorption is especially uncertain. Use this as an illustration, not a precise pharmacokinetic profile.
Questions
TB-500 half-life, answered
What is TB-500's half-life?
TB-500's elimination half-life is approximately 2.5 days — the time for its level in the body to fall by half. This is an approximate figure for illustration; reported values vary.
How long does TB-500 stay in your system?
A compound is essentially cleared after about five half-lives, so TB-500 largely clears in roughly 13 days after your last dose.
How long until TB-500 reaches steady state?
Dosed twice weekly, TB-500 climbs over the first several doses and reaches a steady peak-and-trough pattern in about 13 days, building to about 1.61× a single dose.
Does TB-500 accumulate between doses?
Yes — at twice weekly dosing the model shows roughly 1.61× accumulation at steady state, because each dose is given before the previous one has fully cleared.
