CJC-1295 with GHRP-6 dosage and evidence
Written by Aaron CuhaReviewed Sep 2026
The short answer
CJC-1295 with GHRP-6 is the same two-switch pairing as the GHRP-2 version, but with the hungriest booster of the group in the second slot.
Evidence grade for CJC-1295 with GHRP-6: 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, 9 people given it. A grade counts how much has been done to people, not whether it works.

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.
Same idea as the last one with the hungriest peptide of the family in the second slot. GHRP-6 is the original growth hormone hexapeptide. People who want to eat pick it on purpose. People who do not want to eat find out the hard way. No one has tested this vial.
What people take it for
- Better sleep.
- Eating more, on purpose, when gaining weight is the goal.
- Losing fat and holding muscle.
- Healing faster.
What studies in people showed
Nobody has tested the pair. GHRP-6 does have real human numbers. Nine healthy men got it by drip. It spread through the body in about 7.6 minutes and cleared with a half life of about 2.5 hours. Four of the nine had odd spikes on the way out. The other half of the vial is a puzzle. If it holds the long acting GHRH molecule, its half life is 5.8 to 8.1 days. If it holds the short one most no DAC vials contain, it is gone in minutes. Either way the two halves do not match. One lasts a hundred times longer than the other, or both are gone in hours. For the drug classes together, a 24 hour drip of a GHRP with GHRH beat GHRH alone in healthy older adults. That used the other GHRP, in a clinic. Sellers do not agree on vial sizes, so this page will not give you a per unit number.
What people report
Reports, not study results
The good
- Deep sleep in the first weeks.
- Hunger, if hunger is what you want.
The bad
- Hunger that hits within minutes and is hard to ignore. That is the receptor doing its job, not a bad batch.
- A hot flushed face after the shot.
- Water retention and tingling hands at bigger draws.
- Most people quit it for ipamorelin, and the appetite is why.
- You cannot turn the hunger down on its own.
Where these come from: Peptide and gym forums, clinic write-ups and seller pages. The appetite effect is backed by proper human studies on this drug type.
My bottom line
If you are trying to lose fat, this is the wrong vial. The hunger is the point of the molecule, not a side effect you can dial out.
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 with GHRP-6, what they expect, and what goes wrong. The full account, including the negative reports, is below.

What is CJC-1295 with GHRP-6?
CJC-1295 with GHRP-6 is the same two-switch pairing as the GHRP-2 version, but with the hungriest booster of the group in the second slot. GHRP-6 has been measured in nine healthy men, and half of it was gone in about 2.5 hours. The GHRH half lasts either days or minutes, depending on which molecule is really in the vial. Nobody has studied the blend.
GHRP-6 is the first growth hormone releasing peptide of its kind. It has the strongest hunger effect of the family. That is why it still sells. People who want to eat more pick it on purpose. People who do not want to eat more find out the hard way.
It has been measured in people, and the numbers are worth knowing. Nine healthy men each got a single dose into a vein. The peptide spread through the body with a half-life of about 7.6 minutes. Then half of it was cleared every 2.5 hours or so. Bigger doses gave about the same step up in the amount in the blood. That is a real test in real people. It is also the only test of how GHRP-6 moves through the body in people.
Now look at the other half. If the vial holds real CJC-1295 with DAC, half of it is gone only after 5.8 to 8.1 days. If it holds the mod GRF 1-29 that most no-DAC vials hold, it is gone in minutes. Either way the two halves do not match. Either one lasts a hundred times longer than the other, or both are gone within hours and the vial is a short burst of both. One fixed mix cannot be right for both cases. And the buyer usually cannot tell which case they are in.
On the math, sellers sell this in several splits and no size is standard. So this page does not give a per-unit number. Whatever the split, the plunger moves both. The hunger effect and the GHRH effect go up and down together.
How does CJC-1295 with GHRP-6 work?
GHRP-6 is a small peptide that presses the hunger hormone switch. That sets off a burst of growth hormone and also drives hunger. At higher amounts it also raises the stress hormone cortisol and the hormone prolactin, more than the newer, more targeted peptides do. The GHRH copy makes each growth hormone burst bigger, through a different switch. The case for mixing them is the same two-switch idea tested with drips, not with this vial.
What have studies in people found about CJC-1295 with GHRP-6?
Nobody has studied the pair. Each half has been measured in people, but neither has a study showing a real-life result.
- The pairing of the two drug kinds: in healthy older adults, a GHRP plus GHRH by drip made more growth hormone than GHRH alone.
- GHRP-6: single doses into a vein in nine healthy men. Half was gone in about 2.5 hours. No study of it for any of the reasons people buy it.
- The GHRH half: the published study in people used the long-acting form with DAC, not the stuff usually sold.
- The blend: no published study and no listed trial.
What this does not tell you: Every result here is a growth hormone or IGF-1 blood number. No study of this kind of drug has measured muscle, fat, healing or daily function in the people who buy it, over the time they use it.
What do people who took CJC-1295 with GHRP-6 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.
- Hunger that hits within minutes of the shot and is hard to ignore.
- Deep sleep in the first weeks.
- Flushing and a warm face soon after the shot.
- Water retention and tingling hands at higher amounts.
- People dropping it for ipamorelin because of the hunger.

The state of the research
The hunger GHRP-6 causes is why this version still sells. It is also why most people quit it. It is not a side effect by chance. It comes straight from pressing the hunger hormone switch, the same switch that makes you hungry before dinner. In a fixed blend, the only way to cut the hunger is to cut the GHRH half too.
The older GHRPs also raise the stress hormone cortisol and the hormone prolactin more than ipamorelin does. That is the one reason ipamorelin took their place in this market. That comes from how the drugs work, not from a study comparing blends. No such study exists.

The studies we cite
- Study in people2013Pharmacokinetic study of Growth Hormone-Releasing Peptide 6 (GHRP-6) in nine male healthy volunteers
This study measured how fast GHRP-6 leaves the body, not whether it does anything useful. Nine healthy men each got single doses into a vein, at three strengths. The peptide spread through the body in under eight minutes. Most of it was gone within a few hours. Bigger doses gave bigger amounts in the blood, in step. In four of the nine men the level jumped oddly on the way down, and nobody has explained why. Nine men, one dose at a time, and no benefit measured at all.
Nine healthy men received single intravenous boluses of 100, 200 and 400 micrograms per kilogram. Averaged across doses the distribution half-life was 7.6 plus or minus 1.9 minutes and the elimination half-life 2.5 plus or minus 1.1 hours, with bi-exponential disposition and area under the curve increasing roughly in proportion to dose. Atypical concentration spikes appeared during the elimination phase in four of the nine subjects.
- 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
A single shot of the long-acting version lifts growth hormone for days in healthy adults. That much is solid. Growth hormone ran two to ten times above its usual level for six days or more. The growth factor IGF-1 stayed high for nine to eleven days. Half a dose is still in the body a week later. Read the label with care here. This was CJC-1295 with DAC. What is usually sold as CJC-1295 without DAC is a different molecule that is gone in minutes.
Single subcutaneous injections of CJC-1295 with drug affinity complex raised mean plasma growth hormone two to ten-fold for six days or more and IGF-1 1.5 to three-fold for nine to eleven days in healthy adults, with an estimated half-life of 5.8 to 8.1 days. The material usually sold as CJC-1295 without DAC is a different, short-acting molecule.
- Study in people2004Sustained elevation of pulsatile growth hormone (GH) secretion and insulin-like growth factor I (IGF-I), IGF-binding protein-3 (IGFBP-3), and IGFBP-5 concentrations during 30-day continuous subcutaneous infusion of GH-releasing peptide-2 in older men and women
The idea behind this pairing has worked in people, just not with these ingredients. Healthy older adults got a hunger-hormone type peptide along with GHRH over 24 hours. They made more growth hormone than either drug made alone. That is the closest thing to real proof for pairing these two kinds. Two things set it apart from the product. The study used GHRP-2, not GHRP-6. And it fed the drugs in slowly through a drip, not from a mixed vial.
Combining a ghrelin-receptor agonist with GHRH over 24 hours drove growth hormone secretion beyond either agent alone in healthy older adults. This is the closest thing to combination evidence for the class, and it used GHRP-2 rather than GHRP-6, by infusion rather than by injection from a blended vial.

Common questions
Has CJC-1295 with GHRP-6 been tested in people?
Yes. 9 people given it across 2 completed trials cited here, 0 of which found nothing. CJC-1295 with GHRP-6 is the same two-switch pairing as the GHRP-2 version, but with the hungriest booster of the group in the second slot.
What is the CJC-1295 with GHRP-6 dosage?
No human dose established. Amounts that were given in studies sit in Human evidence on this page. None of them is a personal dose. 2 completed trials, 9 people given it
Is CJC-1295 with GHRP-6 FDA-approved?
Not approved. GHRP-6 has been studied in Cuba to protect tissue from damage, but it has no approval for sale in the United States. The combination has never been reviewed anywhere.
How long does GHRP-6 last?
In nine healthy men given a single dose into a vein, half was gone in about 2.5 hours. It spread through the body in around seven and a half minutes.
Why does it make me so hungry?
It presses the hunger hormone switch, the one that tells you to eat. That is how it works. It is not a dirty batch or a bad vial.
Is the combination studied?
Not this one. A GHRP with GHRH by drip raised growth hormone more than GHRH alone in healthy older adults. That study used GHRP-2 in a research unit.
What vial size should I expect?
There is no standard size. Sellers sell several splits, which is why this page does not give a per-unit number. Work it out from the milligrams on your own label.
Is GHRP-6 or GHRP-2 the better half?
Neither has a study showing a real-life result. GHRP-6 causes more hunger. GHRP-2 has been tested more in people, including a 30 day drip study. Choose by side effects, because there is no data on which works better.
