Pre-filled plasma half-life model for Hexarelin. See how a 1 hours half-life affects steady state, accumulation, peak-trough swing, and clearance timing.
Preset values: 100 mcg every 12 hours, half-life ~1 hours.
~1h half-life. Tachyphylaxis is common; short courses are typical.
Open interactive chart →The half-life used here (1 hours) is the published or well-established estimate for Hexarelin from pharmacokinetic studies. The default dose (100 mcg) and cadence (every 12 hours) 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 1 hours and dosing every 12 hours, the ratio τ/t½ = 12.00 gives an accumulation factor of ~1.00×. That means the steady-state peak plasma mass is about 1.0× the mass of a single dose.
Time to steady state. Approximately 5 half-lives (~0.2 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 Hexarelin plasma half-life of about 1 hours. 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 5 hours for Hexarelin.
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.
