CJC-1295 (with DAC) half-life calculator
CJC-1295 (with DAC) is the long-acting (albumin-bound) form of CJC-1295. Its elimination half-life is about 7 days — so a dose largely clears in roughly 35 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 CJC-1295 (with DAC) stay in your system?
A compound is considered essentially cleared after about five half-lives. With CJC-1295 (with DAC)'s half-life of about 7 days, that's roughly 35 daysafter your last dose. The calculator's dashed line shows that clearance tail.
CJC-1295 (with DAC) steady state & accumulation
Dosed weekly, each CJC-1295 (with DAC) 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 5 weeks — building to about 2× a single dose. That accumulation is why the early weeks can feel different from later on, and why a gradual titrationgives your body time to adjust.
Half-life figures for CJC-1295 (with DAC) are approximate — reported values vary and absorption is especially uncertain. Use this as an illustration, not a precise pharmacokinetic profile.
Questions
CJC-1295 (with DAC) half-life, answered
What is CJC-1295 (with DAC)'s half-life?
CJC-1295 (with DAC)'s elimination half-life is approximately 7 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 CJC-1295 (with DAC) stay in your system?
A compound is essentially cleared after about five half-lives, so CJC-1295 (with DAC) largely clears in roughly 35 days after your last dose.
How long until CJC-1295 (with DAC) reaches steady state?
Dosed weekly, CJC-1295 (with DAC) climbs over the first several doses and reaches a steady peak-and-trough pattern in about 5 weeks, building to about 2× a single dose.
Does CJC-1295 (with DAC) accumulate between doses?
Yes — at weekly dosing the model shows roughly 2× accumulation at steady state, because each dose is given before the previous one has fully cleared.
