Epithalon half-life calculator
Epithalon is a longevity peptide, typically run in short pulsed courses. Its elimination half-life is about 15 minutes, so a dose largely clears in roughly 1 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 Epithalon stay in your system?
A compound is considered essentially cleared after about five half-lives. With Epithalon's half-life of about 15 minutes, that's roughly 1 hours after your last dose. The calculator's dashed line shows that clearance tail.
Epithalon steady state & accumulation
Epithalon's half-life is short relative to daily 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 Epithalon are approximate: reported values vary and absorption is especially uncertain. Use this as an illustration, not a precise pharmacokinetic profile.
Questions
Epithalon half-life, answered
What is Epithalon's half-life?
Epithalon's elimination half-life is approximately 15 minutes, 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 Epithalon stay in your system?
A compound is essentially cleared after about five half-lives, so Epithalon largely clears in roughly 1 hours after your last dose.
How long until Epithalon reaches steady state?
With a half-life of 15 minutes dosed daily, Epithalon clears almost completely between doses, so it doesn't meaningfully accumulate; each dose behaves like the first.
Does Epithalon accumulate between doses?
Not meaningfully. Its half-life is short relative to daily dosing, so it clears between doses (accumulation ≈ 1×).
