Ipamorelin Tracker
Ipamorelin is a selective growth hormone secretagogue noted for minimal appetite and cortisol impact. This page covers its half-life, what that timescale means for keeping a usable record, and how it changes the shape of a log — not what to take or how much.
What Ipamorelin's timing means for tracking
Ipamorelin has a half-life around 2 hours and an estimated activity window of roughly 4. It is fully cleared inside half a day, which puts it firmly in the short-acting group.
The thing that matters for a record is that it works through a pulse. The compound leaves quickly, and the response it prompts is similarly brief. That makes timing the most informative field in the log — not because a schedule should be built around it here, but because an entry with no clock time tells you almost nothing about the day it describes.
Nothing accumulates. Wednesday's entry has no bearing on Thursday's levels, so there is no loading phase to reason about and no reason to read a gap as a lingering deficit.
What to capture in the log
- Log the clock time on every entry — with a 2-hour half-life it is the field carrying most of the information.
- If a routine involves more than one entry a day, record them separately rather than as a daily total.
- Treat each day as independent. Nothing carries into the next.
Worked reconstitution example
Purely as arithmetic, using round numbers rather than a recommendation. If a 5 mg vial were mixed with 2 mL of bacteriostatic water, the concentration would be 2.5 mg/mL. Measuring 200 mcg from that would come to:
8 units on a U-100 syringe
5 mg ÷ 2 mL = 2.5 mg/mL → 200 mcg = 0.08 mL = 8 units
Change either the vial size or the water and this number changes completely. Run your own figures in the reconstitution calculator.
Frequently asked questions
What is the half-life of ipamorelin?
Roughly 2 hours, with an estimated activity window near 4 hours. On the five-half-life convention it is cleared in about 10 hours.
Does ipamorelin build up between doses?
No. It clears well within a day, so levels do not accumulate the way a long half-life compound's do.
How many units is 200 mcg of ipamorelin?
With a 5 mg vial in 2 mL of bacteriostatic water the concentration is 2.5 mg/mL, or 25 mcg per unit, so 200 mcg is 8 units on a U-100 syringe.
