Ipamorelin vs CJC-1295

There is no winner on this page. What is set side by side is the published record behind each one, which is the part the two are rarely compared on.

Both in Growth hormone

Sold as a stack, and each half carries a borrowed claim. Ipamorelin's selling point, that it raises growth hormone without raising stress hormones, was measured in pigs, once, by the company that owned the molecule, and in humans the number of measurements is zero. CJC-1295 is two molecules under one name: the 2 to 10 fold rise lasting six days or more comes from trials of the version with the clip, while the version most people buy and inject daily is the one with the clip removed, and no peer reviewed human study of it exists.

This is not a protocol and neither column is a recommendation. The studied row is what a trial administered to people under supervision. The circulating row is what gets reported in practice, recorded because it is what happens. Where a row is empty it is because nothing has been published, which is a fact about the literature rather than about the compound.
Field	Ipamorelin	CJC-1295
What a trial gave	About 4.2 mg per day, into a veinThe published Helsinn trial, which missed its endpoint	30 to 60 mcg/kg, about 2.25 to 4.5 mgTeichman 2006, trials of 28 and 49 days
What circulates	200 to 900 mcg per day, under the skin	1 to 2 mg per week, DAC version
The gap	Below the studied dose	Below the studied dose
How long it lasts	About two hours. That figure comes from a single study in healthy men where it went into a vein. I could not find a measurement of how long it lasts in a person injecting it under the skin.	About 5.8 to 8.1 days in people for the clipped version, injected under the skin. For the version without the clip, I found no published figure in a person.
Route studied	Into a vein, in hospital	Injected under the skin, in a clinical trial
Route used	Under the skin, at home	Injected under the skin, at home
Vial sizes	5, 10 mg	5 mg

The distance, stated

Below the studied dose

Ipamorelin

Five to twenty one times smaller, and by a route I found no human study of. The smaller number is smaller in a unit no one has converted.

Below the studied dose

CJC-1295

A quarter to a half of one studied injection. Lower, not higher, and still a dose no trial administered.

What people get wrong

Ipamorelin

People believe the headline selling point, that it raises growth hormone without raising stress hormones, is a human finding. It was measured in pigs, once, by the company that owned the molecule, and that same test also failed to detect a rise for an older compound that is known to raise those hormones in people, so the test itself proved nothing. In humans the number of measurements is zero.

CJC-1295

That there is only one CJC-1295. The impressive numbers on vendor pages, a 2 to 10 fold rise in growth hormone lasting six days or more, come from trials of the version with the clip, while the version most people are actually buying and injecting daily is the one with the clip removed, and not one peer reviewed human study of it exists.
