Pre-filled plasma half-life model for CJC-1295. See how a 8 days half-life affects steady state, accumulation, peak-trough swing, and clearance timing.
Preset values: 100 mcg every 2 days, half-life ~8 days.
DAC-linked form: half-life ~8 days. Every-other-day dosing creates steady baseline elevation of GHRH signal.
Open interactive chart →The half-life used here (8 days) is the published or well-established estimate for CJC-1295 from pharmacokinetic studies. The default dose (100 mcg) and cadence (every 2 days) reflect typical standard protocols — not a prescription or recommendation. Your specific product's label and your clinician's protocol override any default here.
Accumulation. With a half-life of 8 days and dosing every 2 days, the ratio τ/t½ = 0.25 gives an accumulation factor of ~6.29×. That means the steady-state peak plasma mass is about 6.3× the mass of a single dose.
Time to steady state. Approximately 5 half-lives (~40.0 days) of consistent dosing before average concentration stops rising. Dose-escalation protocols that change doses before this point are titrating against a still-rising baseline, which is one reason weekly peptides feel "slow" at the start.
The visualizer is a simple first-order single-compartment exponential decay model. It's accurate enough for understanding dosing rhythm, peak-trough ratios, and steady-state math, but not clinical pharmacokinetics. It doesn't model:
For most questions about "how often should I dose," the model is sufficient. For clinical decisions, use the manufacturer's label and a qualified prescriber.
This chart uses an estimated CJC-1295 plasma half-life of about 8 days. Published values can vary by formulation, route, assay, and study design.
A simple first-order model reaches practical steady state after about five half-lives, which is roughly 40.0 days for CJC-1295.
No. It visualizes half-life, accumulation, peaks, and troughs from values you enter. It is not a prescription, dose recommendation, or substitute for the product label or clinician guidance.
Steady state explains why long-half-life compounds can keep rising for weeks after starting or changing a dose, while short-half-life compounds behave more like brief pulses.
