CJC-1295 / Ipamorelin dosage and evidence
Written by Aaron CuhaReviewed Sep 2026
The short answer
CJC-1295 / Ipamorelin is the most popular peptide pair on the market.
Evidence grade for CJC-1295 / Ipamorelin: 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, 20 people given it. A grade counts how much has been done to people, not whether it works.

Dose
No human dose established for this blend
No published study has tested CJC-1295 with ipamorelin together. Each component has its own profile. Commonly reported chips track the CJC-1295 half of the vial and are not a human dose.
Amounts for the CJC-1295 in the blend, in mcg, commonly reported. The ipamorelin moves with it in the label ratio.
Amounts commonly reported for the CJC-1295 in this blend, 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 / Ipamorelin.

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.
This is two growth hormone peptides in one vial. It is the most stacked pair in the peptide world. A vial is usually 5 mg of each, so half the powder is each one. Both nudge your pituitary to put out more growth hormone. They just push different buttons to do it. No study has ever tested these two together. Not in people. Not in animals.
What people take it for
- Better sleep.
- Losing fat and holding on to muscle.
- Healing faster from training and old injuries.
- Feeling younger, on the idea that more growth hormone turns back the clock.
- Some people believe two peptides beat one. Nobody has tested that with this pair.
What studies in people showed
There is no trial of this pair. That is the main thing on this page. What exists is a record for each half. One shot of the first peptide raised growth hormone 2 to 10 times for six days or more in healthy adults. It also raised IGF-1 for nine to eleven days. Its half life was 5.8 to 8.1 days. The second peptide has one human trial. It was given to 117 people after bowel surgery. It was safe. It did not help them eat sooner than a dummy shot did. Now the part that matters most. Those two half lives are nothing alike. One peptide is gone in about two hours. The other is still working a week later. So there is no dosing plan that fits both. Daily is right for one and piles up the other. Twice a week is right for the other and wastes the first. A close cousin of this pair was tested in 20 patients. Adding the second type of peptide about doubled the growth hormone peak, 54.7 against 25.7. But that was one shot through an IV, in a clinic, as a test. It is not this vial and it is not a nightly plan. One note for the calculator on this page. A blend is usually mixed in more water than a single peptide, and drawn on a bigger syringe. The numbers for one peptide do not carry over.
What people report
Reports, not study results
The good
- Deeper sleep in the first two weeks. This is the most common report by far.
- Vivid dreams, usually alongside the sleep change.
- Feeling better recovered from training after a month or two. People put that down to the sleep, not to anything anyone measured.
The bad
- Puffy face and hands, and stiff mornings. Water retention is the classic one here.
- Numb or tingling fingers. People call it carpal tunnel. It goes away when they stop.
- Hunger, which comes and goes and is not the same for everyone.
- Nothing at all. This is common enough that people argue about vendor quality all day.
- A red itchy lump where the needle went in.
- You cannot turn one peptide down. The ratio is set in the powder. If your hands go numb, your only move is to cut both or stop both. You will never know which one did it.
Where these come from: There are no trial exit interviews here, because there is no trial of the blend. These come from peptide forums such as r/Peptides and from clinic and vendor write ups. A 2026 medical review of people self dosing these peptides lists the same problems: fluid retention, aching joints, blood sugar changes and sore injection sites.
My bottom line
The idea behind this pair is real. The vial is not. Two peptides with half lives a hundred times apart do not belong in one bottle, and buying them together means you can never tune either one. If you are going to do this at all, buy two vials.
An opinion, not a finding. I am a coach, not a doctor.

Real people telling you what happened to them. Nobody checked it, and the people who post are not a fair sample, so it cannot prove anything works. It is still the best guide on this page to what people actually do with CJC-1295 / Ipamorelin, what they expect, and what goes wrong. The full account, including the negative reports, is below.

No study in people, animals or cells on this page reports a result for these. That does not prove CJC-1295 / Ipamorelin does nothing for them. It does mean anything you have heard about CJC-1295 / Ipamorelin and one of these did not come from a study cited here.
Show full evidence
What is CJC-1295 / Ipamorelin?
CJC-1295 / Ipamorelin is the most popular peptide pair on the market. It is sold as 5 mg plus 5 mg, or 10 mg plus 10 mg, in one vial, so each peptide is half the powder by weight. No published study has tested CJC-1295 with ipamorelin in people or in animals. And the two peptides clear from the body at speeds roughly a hundredfold apart, so no single shot schedule is right for both.
CJC-1295 and ipamorelin are sold together more often than either is sold alone. The sellers' logic is real science. CJC-1295 copies growth hormone releasing hormone (GHRH) and presses the GHRH switch. Ipamorelin copies ghrelin, the hunger hormone, and presses a second switch. Both switches sit on the same growth hormone cells in the pituitary gland. Pressing both at once gives a bigger burst of growth hormone than pressing either alone. That idea has human evidence behind it. This exact pair in this vial does not.
The math matters more here than on most pages. A 5 mg plus 5 mg vial is half CJC-1295 and half ipamorelin by weight. By number of molecules, the split is nothing like even. CJC-1295 with its DAC hook weighs 3,647.2 Da, and ipamorelin weighs 711.85 Da. So an equal-weight blend gives about 5.1 ipamorelin molecules for every CJC-1295 molecule. Mix a 5 plus 5 vial with 2 mL of bacteriostatic water and it holds 2.5 mg per mL of each. A 10 unit draw on a 100 unit insulin syringe is 0.1 mL, and it gives you 250 micrograms of each peptide. That is inside the range people use for ipamorelin alone. It is also a large, repeated dose of a GHRH copy that takes 5.8 to 8.1 days for the body to clear half of.
That gap in how long they last is the specific problem this blend creates. Ipamorelin clears in about two hours and needs frequent shots to do anything. In healthy adults, one shot of CJC-1295 with DAC kept growth hormone raised for six days or more, and IGF-1 raised for nine to eleven days. Take the vial daily, as most routines say, and the ipamorelin is right while the CJC-1295 piles up. Take it twice a week to suit the CJC-1295, and the ipamorelin does nothing on the five days in between. No schedule serves both. And because the split is fixed in the powder, you cannot lower one without lowering the other.
A second problem: the label does not tell you which molecule you have. Sellers sell both CJC-1295 with DAC, the long-acting version that works for days, and CJC-1295 without DAC. The one without DAC is really modified GRF 1-29, and it clears in roughly half an hour. Both are labeled CJC-1295. They behave so differently that the right schedule for one is wrong for the other by about a hundredfold. The buyer usually cannot tell which is in the vial.
How does CJC-1295 / Ipamorelin work?
Two switches on the same pituitary cell. CJC-1295 presses the GHRH switch, which makes each growth hormone burst bigger. In the DAC version, a hook that grabs albumin, a blood protein, stretches that signal out for days. Ipamorelin presses the ghrelin switch, called GHS-R1a. That releases growth hormone and also eases off somatostatin, the body's brake on growth hormone. In human tests, pressing both kinds of switch gave a bigger burst than either alone. But those tests used the body's own GHRH with GHRP-6, not this pair.
What have studies in people found about CJC-1295 / Ipamorelin?
There is human evidence for CJC-1295 alone, and for ipamorelin alone. There is also human evidence that GHRH plus a growth hormone releasing peptide beats either alone, in a one-time test through a vein. There is no human evidence for CJC-1295 given with ipamorelin.
- CJC-1295 alone, in healthy adults, compared with a dummy shot: one shot raised average growth hormone 2-fold to 10-fold for six days or more, and IGF-1 1.5-fold to 3-fold for nine to eleven days.
- Ipamorelin alone, in its only published human trial, in 117 people after bowel surgery: ipamorelin through a vein was well tolerated. It did not clearly shorten the time to a first meal they could keep down, 25.3 hours versus 32.6 hours on a dummy drip.
- GHRH plus GHRP-6, in 20 patients: the average growth hormone peak was 25.7 micrograms per litre on GHRP-6 alone, and 54.7 micrograms per litre on the two together. This was a one-time hospital test through a vein, not a nightly shot under the skin.
- GHRP-2 with GHRH for 7 to 30 days: the pair could go from simply adding up to boosting each other. Whether the response faded depended on the dose and how often it was given.
What this does not tell you: No trial has given CJC-1295 with ipamorelin to a person. No trial of any GHRH plus GHRP-type pair has measured body shape, strength, sleep or anything else people buy this blend for. The pair evidence that does exist measures a growth hormone peak over 90 to 120 minutes in a clinic. That is a stand-in for a stand-in. Nobody has published whether the two peptides stay stable in one vial. Nobody has published a study to find the right dose of the pair, at any split.
What do people who took CJC-1295 / Ipamorelin 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.
- Deeper sleep in the first two weeks. This is the most common report on this blend, and the one people notice first.
- More vivid dreams, reported along with the sleep change.
- Feeling better recovered from training after a month or two. Users mostly credit the better sleep, not anything they measured.
- Water retention, a puffy face and hands, and stiffness in the morning. This usually shows up after a few weeks, and more often on blends labeled DAC.
- Numbness or tingling in the fingers, which users describe as carpal tunnel symptoms. It usually goes away after stopping.
- Hunger, which comes and goes. Users treat it as one clue to whether their vial holds what the label says.
- No effect at all. This is common enough that seller purity is a standing topic on the forums.
- Redness or an itchy lump where the shot went in.
Sources: Peptide user forums including r/Peptides, clinic and vendor write-ups, and the adverse-effect domains listed in the 2026 Frontiers in Endocrinology review of self-administered growth hormone axis peptides, which names fluid retention, myalgia and arthralgia, dysglycaemia, prolactin and cortisol elevations and injection site reactions. None of this comes from a trial of the blend, because no trial of the blend exists.
The state of the research
This blend has no trial, and not because someone tried and failed. A fixed mix of two unapproved peptides is not something anyone can patent or get approved, so there is no money to test it. That is about money, not a verdict on the science. And the science of pairing GHRH with a growth hormone releasing peptide is genuinely supported. What is not supported, and what nobody is working on, is this split, at these doses, on this schedule.
The real cost of the blend is the one nobody mentions when selling it. On a single peptide, if you get water retention, carpal tunnel symptoms, numb fingers, achy joints or rising fasting blood sugar, you lower that peptide. On a blend you cannot. The split is set in the powder. Lowering the dose to fix a CJC-1295 problem also takes away the ipamorelin, and you can never find out which one caused what. The same goes for appetite and cortisol effects, which differ between these peptides. A blend buys you convenience. It costs you every way you would otherwise have to figure out what is going on.

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 injection kept growth hormone raised for the better part of a week. Healthy adults were given a single shot of CJC-1295 or a dummy shot, and their blood was tracked afterwards. Growth hormone ran several times higher for six days or more, and IGF-1, the hormone it drives, stayed up for nine to eleven days. The body takes about a week to clear half a dose. No ipamorelin was given here. That long tail is why dosing a blend of the two every night makes no sense.
Two randomised placebo-controlled trials in healthy adults. A single injection of CJC-1295 raised mean growth hormone 2-fold to 10-fold for six days or more and IGF-1 1.5-fold to 3-fold for nine to eleven days, with an estimated half-life of 5.8 to 8.1 days. This is the CJC-1295 component alone. No ipamorelin was given, and this is the measurement that makes daily dosing of a blend incoherent.
- Study in people2002Diagnosis of growth hormone deficiency in adults by testing with GHRP-6 alone or in combination with GHRH: comparison with the insulin tolerance test
Pushing two different buttons at once made the pituitary release about twice as much growth hormone. Twenty patients were given a ghrelin type drug on one day, and the same drug plus a growth hormone releasing hormone on another. The peak roughly doubled when the two were combined. This is the closest human support for pairing these two kinds of peptide. It was one dose into a vein, given as a hospital test of the pituitary. It was not CJC-1295 with ipamorelin, and nobody took it nightly.
Twenty patients given GHRP-6 at 1 microgram per kilogram alone, and on a separate day with GHRH at 1 microgram per kilogram. In the growth hormone sufficient group the mean peak was 25.7 micrograms per litre on GHRP-6 alone and 54.7 micrograms per litre on the combination. This is the closest human evidence that a GHRH plus a ghrelin mimetic beats one alone, but it used GHRH and GHRP-6 as a single intravenous diagnostic test, not CJC-1295 with ipamorelin injected nightly.
- Study in people1996GHRP-2, GHRH and SRIF interrelationships during chronic administration of GHRP-2 to humans
Take these peptides for weeks and what they do changes, in either direction. Younger and older men and women were given one peptide, the other, or both, for a week to a month. Sometimes the pair did more together than the two apart. Sometimes the response faded instead. Which one happened depended on the dose and on how often it was given. A blend fixes both of those for you, in a ratio you cannot change, which is exactly the wrong thing to fix.
Bowers and Granda-Ayala gave younger and older men and women GHRP-2, GHRH, or both together for 7 to 30 days. Chronic dosing of either one could turn an additive combined response into a synergistic one, and whether the response desensitised depended on the dose and the frequency. The honest reading is that additivity is not fixed and that dose and schedule decide whether you get more or less over time, which is exactly what a fixed-ratio vial takes out of your hands.
- Review of studies2026Injectable Peptides in Sports Medicine: A Structured Narrative Review of Evidence, Safety, and Antidoping Implications
A review of injectable peptides used in sports medicine. It rates growth hormone peptides, including CJC-1295, ipamorelin and tesamorelin, as still experimental. Their safety is unclear, product quality is a worry, and most sports ban them. The only drug group the authors found backed by solid trials that held up when repeated was the GLP-1 weight loss drugs.
Structured review of injectable peptides published between January 2020 and August 2025. Growth hormone axis secretagogues including CJC-1295, ipamorelin and tesamorelin are classed as investigational with uncertain safety profiles, product quality concerns and widespread antidoping restrictions. GLP-1 receptor agonists were the only class the authors found supported by reproducible randomised evidence.

Common questions
Has CJC-1295 / Ipamorelin been tested in people?
Yes. 20 people given it across 2 completed trials cited here, 0 of which found nothing. CJC-1295 / Ipamorelin is the most popular peptide pair on the market.
What is the CJC-1295 / Ipamorelin dosage?
No human dose established for this blend. No published study has tested CJC-1295 with ipamorelin together. Each component has its own profile. Commonly reported chips track the CJC-1295 half of the vial and are not a human dose. Amounts for the CJC-1295 in the blend, in mcg, commonly reported. The ipamorelin moves with it in the label ratio.
Is CJC-1295 / Ipamorelin FDA-approved?
Not approved. Neither part is an approved drug, and the mix has never been sent to a regulator or studied.
Has anyone studied CJC-1295 with ipamorelin together?
No. Not in people, not in animals. The published pair studies used the body's own GHRH with GHRP-6 or GHRP-2, given once through a vein as a test. That work supports the idea of pressing both switches. It tells you nothing about this vial, this split, or nightly dosing.
How much of each am I actually injecting?
On a 5 mg plus 5 mg vial, the powder is half of each by weight. Add 2 mL of bacteriostatic water and you have 2.5 mg per mL of each peptide. So a 10 unit draw is 250 micrograms of CJC-1295 and 250 micrograms of ipamorelin. By number of molecules, equal weight means about five ipamorelin molecules for every one CJC-1295 molecule, because CJC-1295 is about five times heavier.
Why does the dosing schedule matter so much on this one?
Because the two halves clear at wildly different speeds. Ipamorelin is gone in a couple of hours. One shot of CJC-1295 with DAC kept growth hormone up for six days or more. Daily shots suit the ipamorelin, but pile the CJC-1295 on top of itself. Twice a week suits the CJC-1295, but wastes the ipamorelin. No schedule fits both.
Is my vial DAC or no DAC, and does it matter?
It matters a lot, and the label usually will not tell you. CJC-1295 with DAC lasts days. CJC-1295 without DAC is modified GRF 1-29, and it lasts about half an hour. Both are sold under the same name. If you do not know which you have, you cannot know if your schedule is right.
Can I just lower the dose if I get puffy or my hands go numb?
You can lower the dose, but you lower both peptides at once. That is the real cost of any blend. You cannot back off one and keep the other, and you can never work out which one caused the problem. Two separate vials cost more and take an extra draw. They are the only way to actually adjust each dose.
Will this raise my IGF-1?
In healthy adults, one shot of CJC-1295 on its own raised IGF-1 1.5-fold to 3-fold for nine to eleven days. No study has measured what the blend does to IGF-1 over months of repeated shots. Nor has anyone checked whether that IGF-1 change turns into anything a person can feel.
