Thymosin Alpha-1 half-life calculator
Thymosin Alpha-1 is an immune-support peptide (Zadaxin). Its elimination half-life is about 2.5 hours — so a dose largely clears in roughly 13 hours. 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 Thymosin Alpha-1 stay in your system?
A compound is considered essentially cleared after about five half-lives. With Thymosin Alpha-1's half-life of about 2.5 hours, that's roughly 13 hoursafter your last dose. The calculator's dashed line shows that clearance tail.
Thymosin Alpha-1 steady state & accumulation
Thymosin Alpha-1's half-life is short relative to twice weekly dosing, so it clears almost completely between doses and doesn't meaningfully accumulate (about 1×). Each dose behaves much like the first — the chart shows a clean spike that returns to baseline before the next one.
Half-life figures for Thymosin Alpha-1 are approximate — reported values vary and absorption is especially uncertain. Use this as an illustration, not a precise pharmacokinetic profile.
Questions
Thymosin Alpha-1 half-life, answered
What is Thymosin Alpha-1's half-life?
Thymosin Alpha-1's elimination half-life is approximately 2.5 hours — 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 Thymosin Alpha-1 stay in your system?
A compound is essentially cleared after about five half-lives, so Thymosin Alpha-1 largely clears in roughly 13 hours after your last dose.
How long until Thymosin Alpha-1 reaches steady state?
With a half-life of 2.5 hours dosed twice weekly, Thymosin Alpha-1 clears almost completely between doses, so it doesn't meaningfully accumulate — each dose behaves like the first.
Does Thymosin Alpha-1 accumulate between doses?
Not meaningfully — its half-life is short relative to twice weekly dosing, so it clears between doses (accumulation ≈ 1×).
