# Ipamorelin Dosage in the Research: Doses, Routes, Half-Life

> Ipamorelin dosage as documented in studies: the doses and routes given to humans and animals, the ~2-hour half-life, and why no human dose can be recommended. Cited.

The doses and routes administered in published human and animal research, the pharmacokinetics, and why community 'stack' regimens have no clinical basis.

## The short version

There is no recommended human ipamorelin dosage, because no health authority has ever approved the peptide or set a dose for it. What this page can do is report, in plain terms, the doses researchers actually gave — to people in two studies and to animals in several more — and how the body cleared them.

A few anchors: the human pharmacology study used intravenous doses far smaller than anything you would read in a forum, and the one human treatment trial used 0.03 mg/kg twice a day for up to a week [2][3]. The peptide leaves the bloodstream fast (about a 2-hour half-life) and produces a single GH pulse roughly 40 minutes after dosing [2]. None of this is a protocol to follow — it is a record of what was measured. No "you should" appears anywhere on this page.

## Doses recorded in human studies

Only two human studies provide dosing detail, and they were run for pharmacology and for a surgical indication — not to optimize any wellness outcome.

The pharmacokinetic study gave healthy men five 15-minute intravenous infusions ranging from 4.21 to 140.45 nmol/kg, one dose level per group of eight [2]. The Phase 2 ileus trial gave 0.03 mg/kg intravenously twice daily, on postoperative days 1 through 7 or until discharge, to 114 bowel-resection patients [3]. That trial missed its primary endpoint, so its dose carries no efficacy endorsement — it is simply the dose that was tested.

Both used the intravenous route under medical supervision. The subcutaneous self-injection route that dominates community use has never been characterized in a human study for dose, exposure, or safety.

## Doses recorded in animal studies

Animal dosing spans a wide range because the studies asked different questions. The rat bone-growth study used subcutaneous ipamorelin at 18, 90, and 450 μg/day, split into three daily doses over 15 days [4]. The 2024 ferret cachexia study used 1-3 mg/kg given intraperitoneally [5]. Older ileus work in rats used 0.1-1 mg/kg intravenously, repeated four times a day.

These figures are reported as dose-per-kilogram in specific species — they do not translate into a human dose, and the field deliberately avoids that conversion for an unapproved compound. They are here to show the research range, nothing more.

## Half-life, kinetics, and routes

In healthy human volunteers, ipamorelin showed a terminal half-life of about 2 hours, clearance of 0.078 L/h/kg, and a steady-state volume of distribution of 0.22 L/kg, with the GH pulse peaking near 40 minutes post-dose [2]. In rats, plasma clearance runs roughly 5-fold lower than GHRP-6.

Routes studied include intravenous (human pharmacology and trials; rodent efficacy), subcutaneous (rodent bone and body-composition work, and the dominant route in community use), intranasal (rodent pharmacology, ~20% bioavailability), and intraperitoneal (rodent and ferret studies). Plain ipamorelin is **not** orally active — only engineered analogs derived from it achieved meaningful oral absorption, and only in dogs (~10%) [7].

## How much cjc-1295 ipamorelin should i take

On "how much cjc-1295 ipamorelin should i take," there is no research-based answer, and this site will not invent one. No controlled human trial has ever studied the cjc-1295 ipamorelin combination, so no studied dose for the pair exists. The community 'stack' regimens circulating online — typically fixed microgram amounts injected subcutaneously — have no peer-reviewed human dosing basis and are best understood as anecdotal, not validated [3]. The only human ipamorelin doses on record are the intravenous research doses above [2], which were given under medical supervision for entirely different purposes. Dosing decisions about an unapproved research compound are outside what any digest should provide.

## How to reconstitute cjc-1295 ipamorelin 5mg

Questions like "how to reconstitute cjc-1295 ipamorelin 5mg" come up because these peptides ship as a lyophilized (freeze-dried) powder that must be mixed with liquid before any handling. In the research-supply literature, lyophilized ipamorelin is typically reconstituted with bacteriostatic water and kept refrigerated, since peptides degrade with heat and repeated freeze-thaw cycles. Those are general laboratory-handling observations, not a preparation instruction for use in a person [2]. This site does not provide reconstitution recipes, injection volumes, or use directions, because doing so for an unapproved compound would cross from documenting research into directing use — a line it holds.
