What it is

CJC-1295 / Ipamorelin, in plain terms

CJC-1295 is a modified copy of the first 29 amino acids of growth-hormone-releasing hormone (GHRH), the signal your brain already uses to call for growth hormone. Ipamorelin is a five-amino-acid peptide that mimics ghrelin at a second, separate receptor.

Neither one is growth hormone. Both ask your pituitary gland to release its own, which keeps your body's feedback loops in the picture.

How it works

What it does in the body

CJC-1295 binds the GHRH receptor on the pituitary cells that make growth hormone. Ipamorelin binds the growth hormone secretagogue receptor. Because they work through different doors, the two are paired on the reasoning that the combined signal is stronger than either alone.

Released growth hormone then prompts the liver to make IGF-1, which carries out much of growth hormone's downstream work. Your provider tracks IGF-1 to see how you are responding.

The evidence

What the research shows, and what it doesn’t

Every finding is labelled by the kind of study it came from, with the source linked.

Human trial

In two placebo-controlled trials in healthy adults, a single dose of long-acting CJC-1295 raised average growth hormone two to ten times for six days or more, and IGF-1 one and a half to three times for nine to eleven days.

Teichman et al., J Clin Endocrinol Metab, 2006
Human study

In healthy men, CJC-1295 raised baseline growth hormone while the body's natural pulsing pattern of release was preserved.

Ionescu & Frohman, J Clin Endocrinol Metab, 2006
Human study

In 40 healthy men given ipamorelin by infusion, growth hormone peaked in under an hour and returned to baseline within about six hours.

Gobburu et al., Pharmaceutical Research, 1999
Animal and lab

Ipamorelin released growth hormone without a meaningful rise in cortisol or ACTH in animal work, which is why it is described as a selective secretagogue.

Raun et al., Eur J Endocrinol, 1998
Not yet studied

No human trial has tested this combination, and the CJC-1295 studies used its long-acting form. Human studies measured hormone levels, not muscle, fat loss, sleep or recovery. Reports of those benefits come from patient experience.

Sigalos & Pastuszak, Sexual Medicine Reviews, 2018

Published research describes what was observed in a study. It is not a promise of what any product will do for you. Your provider will talk through what is realistic.

What to expect

On the protocol

01

How it's taken

A small injection just under the skin, usually in the evening on an empty stomach. Your provider sets the dose and the weekly schedule and teaches you the technique. It arrives already reconstituted by the pharmacy, so there is no powder to mix and nothing to measure out.

02

What people report

Patients most often describe changes in sleep and recovery first, with body-composition changes later. These are patient reports, not trial outcomes, and results vary.

03

How it's monitored

Growth hormone signalling can raise blood sugar, so your provider checks IGF-1 and glucose markers at baseline and again during treatment.

Safety

Know this before you start

Your provider reviews your full history. Tell them about every medication and condition, including any history of cancer.

Reported side effects

  • Redness or irritation at the injection site
  • Flushing or headache
  • Water retention or joint discomfort
  • Increased appetite
  • A possible rise in blood glucose

Who should not use it

  • Active cancer or a recent history of cancer
  • Pregnancy or breastfeeding
  • Uncontrolled diabetes
  • Significant heart disease
  • Athletes subject to drug testing
Tested athletes

Not for drug-tested athletes

CJC-1295 and ipamorelin are both named on the World Anti-Doping Agency Prohibited List and are banned at all times, in and out of competition.

FAQ

CJC-1295 / Ipamorelin questions, answered

Is this the same as taking growth hormone?

No. These peptides signal your pituitary gland to release your own growth hormone rather than supplying it. Human studies confirm they raise growth hormone and IGF-1, which is different from proving a specific clinical benefit.

Is CJC-1295 / Ipamorelin FDA-approved?

No. Neither peptide is approved by the FDA for any condition. When prescribed it is a compounded medication, which has not been reviewed by the FDA for safety, effectiveness or quality.

Will it build muscle or burn fat?

That has not been demonstrated in human clinical trials of these peptides. Studies in people measured hormone levels. Your provider will talk through what is realistic for you.

How is it taken?

As a small subcutaneous injection, usually in the evening. Your provider sets the dose and schedule and monitors your labs.

What are the side effects?

The most commonly reported are injection-site irritation, flushing, headache, water retention and increased appetite. Blood sugar can rise, which is why labs are monitored. Long-term safety has not been studied.

I compete in a tested sport. Can I use it?

No. Both peptides are on the WADA Prohibited List and are banned at all times. Military members should also check their service's prohibited list.
