CJC-1295 dosage and evidence
Written by Aaron CuhaReviewed Sep 2026
The short answer
CJC-1295 is a lab-made copy of the body's growth hormone releasing signal, built to last longer. It keeps growth hormone and IGF-1 raised for days.
Evidence grade for CJC-1295: Limited. The rule: people have taken it in a published study, but fewer than 100 of them. The sum on this page: 2 completed trials, none stating how many people. A grade counts how much has been done to people, not whether it works.

Dose
No human dose established
Amounts that circulate in forums and on vendor pages are not a human dose. Amounts that were given in studies sit in Human evidence on this page.
Commonly reported amounts for the no-DAC form, in mcg. The DAC form is usually reported in mg per week: enter that and switch the unit to mg.
Amounts commonly reported for the no-DAC form of CJC-1295, recorded for this archive's reconstitution calculator, are 100, 200 and 300 mcg. They are self-reports rather than trial doses, and this archive does not recommend any of them. No human dose has been established for CJC-1295.

In plain English
In plain English, from Aaron
This is how I would explain it to a friend. The evidence, with the numbers, is further down the page.
CJC-1295 is a shot that tells the gland in your brain to make more growth hormone. The long acting kind keeps that signal on for about a week from one shot. It is almost always sold as a pair with ipamorelin. Of the two, this is the one with real human data on raising growth hormone. It is not approved for anything.
What people take it for
- Building muscle and losing fat without taking growth hormone itself.
- Deeper sleep and faster recovery from training.
- Looking and feeling younger as growth hormone drops with age.
- Healing joints and tendons.
What studies in people showed
There are two small trials in healthy adults. One shot raised growth hormone 2 to 10 times for six days or more. It raised IGF-1, the growth signal that hormone makes, 1.5 to 3 times for 9 to 11 days. The drug has a half-life of about 6 to 8 days, so it hangs around. A second study found the body kept its normal pulses of growth hormone while the drug was on board. The low point between pulses was 7.5 times higher a week after one shot. That is it. Those trials measured hormone levels in the blood. They did not measure muscle, fat, sleep or recovery. Nobody has tested those in people. One more thing. The trials used the long acting version. A lot of what is sold online is a short version that lasts minutes, and it was not in these trials.
What people report
Reports, not study results
The good
- Deeper sleep, often the first thing people notice, usually within a week or two.
- Feeling recovered faster after hard workouts.
- A leaner look after a few months, usually with training and diet already in place.
- Some say their skin and hair look better.
The bad
- Puffy hands and feet from holding water. This is the classic growth hormone side effect and it shows up here.
- Numb or tingling hands, sometimes at night.
- Flushing, a warm face and a mild headache right after the shot.
- Red or sore spots where the needle went in.
- Not knowing what is in the vial. This is sold as a research chemical and nobody tests it for you.
Where these come from: No trial exit interviews exist for this drug. The 2006 trials were about blood hormone levels and did not report side effects in a way I can pass on. The reports above come from user forums, mostly r/Peptides, and from longevity clinic write-ups that sell the pair.
My bottom line
The human data shows it raises growth hormone and stops there. Nobody has shown it builds muscle or burns fat in people. It is a grey market drug with a known water and tingling problem, and I would not put it in my body on that evidence.
An opinion, not a finding. I am a coach, not a doctor.

What is CJC-1295?
CJC-1295 is a lab-made copy of the body's growth hormone releasing signal, built to last longer. It keeps growth hormone and IGF-1 raised for days.
CJC-1295 is a lab-made copy of GHRH, the brain signal that tells the body to release growth hormone. Some versions carry an add-on called DAC. It sticks to albumin, a protein in the blood, so the drug lasts days instead of minutes. That keeps growth hormone and IGF-1 raised for a long time.
In studies in healthy adults, some people got one shot of the drug and others got a dummy shot. One shot raised average growth hormone two to ten times for six days or more. It raised IGF-1 one and a half to three times for nine to eleven days. Its half-life, the time for half of it to leave the body, was 5.8 to 8.1 days. A second study found the body's natural bursts of growth hormone kept going. A week after one dose, the lowest growth hormone level was 7.5 times higher, and the bursts came just as often and just as strong.
It is often studied together with ipamorelin. It is not an approved drug.
How does CJC-1295 work?
It switches on the GHRH receptor on the pituitary gland, which makes the gland release more growth hormone. The DAC version sticks to albumin in the blood, so it keeps working longer.
What have studies in people found about CJC-1295?
CJC-1295 has real data in people, and all of it is about hormone levels in healthy volunteers. A single shot raised growth hormone 2 to 10 times for six days or more, and IGF-1 1.5 to 3 times for nine to eleven days. The only study that tested a health result, in 120 people with HIV and belly fat, was stopped in 2006 and never reported a result.
- Two dose-rising studies in healthy adults aged 21 to 61, 2006, lasting 28 and 49 days: nobody knew who got the drug and who got a dummy. A single shot under the skin raised growth hormone 2 to 10 times, depending on dose, for 6 days or more. IGF-1 rose 1.5 to 3 times for 9 to 11 days. Half of the drug was gone in 5.8 to 8.1 days. After several doses, IGF-1 stayed above its starting level for up to 28 days. There were no serious side effects, and it was easiest to take at 30 and 60 mcg/kg.
- Growth hormone pulses in healthy men aged 20 to 40, 2006: blood was taken every 20 minutes for 12 hours overnight, before and one week after a single shot of 60 or 90 mcg/kg. The lowest growth hormone level rose 7.5 times, the average rose 46 percent, and IGF-1 rose 45 percent. The number and size of pulses did not change. The two doses worked the same. The rise in IGF-1 did not track any measure of growth hormone release.
- Blood proteins in 11 healthy young men, before and a week after one shot: two blood proteins fell and three rose. This looked for blood markers only, and measured no health result.
- The one study of a health result, with no result: NCT00267527 tested a low dose, a high dose or a dummy for 12 weeks, plus 6 weeks of follow-up, in 120 people with HIV and belly fat. It ran at several sites, nobody knew who got what, and the maker, ConjuChem, paid for it. It was listed to start in December 2005 and end in September 2006. It is marked as stopped. The record gives no reason and posts no results, and no CJC-1295 study has been registered since.
- FDA's safety page on compounding substances, updated 22 April 2026: FDA has found serious side effects linked to CJC-1295, including a faster heart rate and a body-wide reaction from blood vessels opening wide. It also flags a risk of immune reactions by some routes, and trouble confirming what is in the vial. It says the medical data are limited.
- The version most often sold, CJC-1295 without DAC, is not the version that was studied. A 2026 review puts it in the lowest of four evidence groups, meaning no human studies checked by outside scientists exist at all, alongside PEG-MGF and IGF-1 LR3.
What this does not tell you: Raising growth hormone and IGF-1 is a blood test result, not a health result. No published study in people has measured fat, lean mass, strength, recovery, sleep, bone or any symptom. The longest study ran 49 days, nobody over 61 took part, and everyone was healthy. The study that would have answered the health question was stopped without explanation and never reported, so it tells us nothing either way. And the data above belong to the DAC form. The form without DAC, sold as modified GRF 1-29, has no study data of its own in people.
What do people who took CJC-1295 report?
This is what real people say happened to them, good and bad. Nobody measured it. A report cannot tell a real effect from the lift people get just from expecting it to work, from a diet or training change made at the same time, or from what was really in the vial. We still put it near the top. It is the next best thing to a study in people: what happens when real people use it, including what goes wrong.
- Discussed almost entirely as half of a pair with ipamorelin rather than on its own, to the point that the two are usually written as a single item. No self-report in this sample separates them.
- Described dosing appears as a combined figure with ipamorelin, commonly around 100 mcg of this alongside 200 mcg of the other, several times a week on forum cycle patterns rather than any published schedule.
- Users state repeatedly that it will not cause weight loss and correct people who expect it to, usually redirecting them to GLP-1 drugs for that and positioning this as recovery, sleep and body composition support.
- Older users report getting less from growth hormone release peptides than younger ones and several describe moving to growth hormone itself instead.
- Negative reports are mostly no noticeable effect, and cost. Side effect discussion is comparatively thin, which is itself worth noting rather than reading as reassurance.
- A caution about the search term rather than the compound: the same abbreviation is used by judicial conduct commissions in several jurisdictions, and a large share of raw results for it are unrelated legal material. Only clearly peptide-related discussion was used here, which makes this entry thinner than the comment count would suggest.

The state of the research
CJC-1295 is the opposite of the no-patent story that explains most of this group, and that makes its record read differently.
This was a drug a company owned. ConjuChem built it as a version of the body's growth hormone release signal that sticks to albumin, a common blood protein. The DAC chemistry was designed to stretch the natural signal's life in the body from minutes to nearly a week. That is an invention a company can own, it had a company behind it, and the company acted like one. It published its early dosing studies in healthy volunteers in a major hormone journal in 2006. Then it registered a larger study at several sites, against a dummy, with nobody knowing who got what, in 120 people with HIV and belly fat. Somebody was willing to pay for the answer.
The answer never came. The study is listed as stopped, with an end date of September 2006. The record gives no reason, no results were posted, and in the twenty years since, no other CJC-1295 study has been registered anywhere. A stopped study with no report tells you close to nothing, and that is the point, rather than filling the gap with a guess. It is not a failed study, because no result was published. It is not a successful one either, because the programme stopped. It is a gap where a finding should be, and the only people who know which it was are the ones who stopped it.
What is left in the research is the half of the programme that was published: the dosing studies in healthy volunteers. That half is exactly what makes the peptide easy to sell, because it shows in clean numbers that the compound raises a hormone level as designed. It is also exactly the half that cannot tell you whether anything follows from that. A drug that raises IGF-1 45 percent has been shown to raise IGF-1 45 percent. Whether that changes body shape, recovery or anything a person would notice is the question the stopped study was built to answer.
One more point gets lost in the market. The studies above used the DAC version. The version sold most often, CJC-1295 without DAC, is a different molecule that lasts a much shorter time in the body and has no study record in people at all. A 2026 review puts it in the same evidence group as compounds nobody has ever given to a person. A buyer reading the 2006 dosing results on a product page for the no-DAC form is reading about something else.

The studies we cite
- Study in people2006Prolonged stimulation of growth hormone (GH) and insulin-like growth factor I secretion by CJC-1295, a long-acting analog of GH-releasing hormone, in healthy adults
One shot lifted growth hormone for over a week, and that is the whole of what was measured. Healthy adults got a single injection of CJC-1295 or a dummy injection, and nobody involved knew which. Growth hormone in the blood then ran two to ten times higher for six days or more. IGF-1, the hormone the liver makes in response, stayed one and a half to three times higher for nine to eleven days. Nobody measured muscle, fat, strength, sleep or how anyone felt.
Two randomized placebo-controlled trials in healthy adults: a single injection raised mean GH 2- to 10-fold for 6 days or more and IGF-1 1.5- to 3-fold for 9 to 11 days; estimated half-life 5.8 to 8.1 days.
- Study in people2006Pulsatile secretion of growth hormone (GH) persists during continuous stimulation by CJC-1295, a long-acting GH-releasing hormone analog
The drug lifted growth hormone without flattening the body's own rhythm. Healthy men got a single dose. A week later their lowest growth hormone readings were about seven and a half times higher than before, average growth hormone was up by roughly half, and IGF-1 was up by roughly half. The pulses the body normally releases still came just as often and just as strongly. This is blood chemistry only. No health outcome was measured, and the group was small.
In healthy men, CJC-1295 raised trough GH 7.5-fold, mean GH 46% and IGF-1 45% one week after a single dose while GH pulse frequency and amplitude were unchanged.
- Study in people2005A Study to Evaluate CJC 1295 in HIV Patients With Visceral Obesity
The one trial that could have shown whether CJC-1295 does anything useful stopped, and never reported. It was built to give 120 people with HIV related belly fat a low dose, a high dose or a dummy for twelve weeks. It was listed as finishing in September 2006. The record says terminated, gives no reason, and posts no results. No trial of this compound has been registered anywhere in the twenty years since. A trial that stops and reports nothing is itself a finding.
A multicenter, randomized, placebo-controlled, double-blind Phase 2 of low-dose and high-dose CJC-1295 for 12 weeks with 6 weeks of follow-up in 120 HIV patients with visceral obesity. Listed start December 2005, listed completion September 2006, status TERMINATED with no reason given and no results posted. It is the only registered trial of CJC-1295 with a clinical endpoint, and no CJC-1295 trial has been registered since.
- Study in people2009Activation of the GH/IGF-1 axis by CJC-1295, a long-acting GHRH analog, results in serum protein profile changes in normal adult subjects
This looked at proteins in the blood, not at anything a person would notice. 11 healthy young men gave blood before a CJC-1295 injection and again a week later. Five protein spots shifted: two fell and three rose. That is a signal that something changed in the blood. It is not weight, muscle, strength, sleep or any symptom, and none of those was measured.

- Review of studies2026The emerging landscape of performance-enhancing peptides modulating GH-IGF1 axis: bridging the gap between clinical evidence and patient self-administration
The version most people buy has no human studies behind it at all. This review sorts growth hormone peptides into four evidence groups. It puts CJC-1295 without DAC in the bottom group, meaning no human study of it checked by outside scientists exists, alongside PEG-MGF and IGF-1 LR3. The DAC version sits higher, thanks to the 2006 dosing studies in healthy volunteers. These are two different molecules, and the human data belongs to the one sold less often.
Places CJC-1295 without DAC in the lowest of four evidence tiers, defined as compounds with no peer-reviewed human studies at all, alongside PEG-MGF and IGF-1 LR3, while the DAC form sits in an intermediate tier on the strength of the 2006 ascending-dose pharmacology.

Common questions
Has CJC-1295 been tested in people?
Yes. 0 people given it across 2 completed trials cited here, 1 of which found nothing. CJC-1295 is a lab-made copy of the body's growth hormone releasing signal, built to last longer. It keeps growth hormone and IGF-1 raised for days.
What is the CJC-1295 dosage?
No human dose established. Amounts that circulate in forums and on vendor pages are not a human dose. Amounts that were given in studies sit in Human evidence on this page. Commonly reported amounts for the no-DAC form, in mcg. The DAC form is usually reported in mg per week: enter that and switch the unit to mg.
Is CJC-1295 FDA-approved?
Not FDA-approved
Why is CJC-1295 often paired with ipamorelin in research?
They work on two different receptors, GHRH and ghrelin. Studies look at whether taking both gives bigger bursts of growth hormone than either one alone.
Should CJC-1295 be cycled?
No study in people has set an on and off schedule. One dose kept the lowest growth hormone level about 7.5 times higher a week later, and the natural bursts came just as often and just as strong. That argues against the body quickly getting used to it over that time. It does not support any set number of weeks. Plans shared online have not been tested. This site does not invent a schedule.
