GHRP-6 dosage and evidence
Written by Aaron CuhaReviewed Sep 2026
The short answer
GHRP-6 is an early peptide that makes the body release growth hormone. It also makes you very hungry.
Evidence grade for GHRP-6: Limited. The rule: people have taken it in a published study, but fewer than 100 of them. The sum on this page: 5 completed trials, 42 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.
GHRP-6 makes your body release growth hormone and makes you very hungry. It was one of the first shots of its kind, from the early 1990s. People stack it with CJC-1295 for a bigger release. It is not an approved drug anywhere.
What people take it for
- More growth hormone for muscle and recovery.
- Putting on size, because the hunger makes it easy to eat a lot.
- Better sleep and healing on the growth hormone bump.
- Stacking with CJC-1295 or ipamorelin.
What studies in people showed
There is no human trial on this page. None. All of it is rats, pigs and cells. In 1991 the first work showed it releases growth hormone in rats through its own receptor. In 1996 that receptor was found. Then came a head to head in rat cells, rats and pigs. Ipamorelin released about as much growth hormone as GHRP-6. And ipamorelin did it without the extra hormone mess. That is why ipamorelin got built. GHRP-6 also raises cortisol and prolactin. That is the reason people moved on from it.
What people report
Reports, not study results
The good
- Very strong hunger, which hard gainers use on purpose to eat more.
- Deep sleep and vivid dreams.
- Better pumps and fuller muscles within a couple of weeks.
The bad
- Extreme hunger soon after the shot. This is the famous one. People say it feels like they have not eaten in days.
- Water retention, puffy face and hands.
- Tingling or numb hands from the growth hormone.
- Raised cortisol and prolactin. Cortisol is the stress hormone. Prolactin can hurt sex drive. Neither is what you want from a muscle shot.
- Feeling wiped out and sleepy after the shot.
Where these come from: The cortisol and prolactin effect is from the science summary on this page, not from a human trial. The hunger, water, tingling and sleep reports are from r/Peptides and bodybuilding forums and from vendor side effect guides. None of it is from a human trial, because there is no human trial on this page.
My bottom line
Thirty year old rat science, no human trial, and it raises your stress hormone while it makes you eat. I would not put this in my body. If you want more growth hormone the newer ones are cleaner, and the trial record for all of them is thin.
An opinion, not a finding. I am a coach, not a doctor.

What is GHRP-6?
GHRP-6 is an early peptide that makes the body release growth hormone. It also makes you very hungry.
GHRP-6 is one of the first peptides made to raise growth hormone. There are no human studies on this page. It works through the ghrelin switch, the same one the hunger hormone uses. So it raises growth hormone and makes you much hungrier. It also raises cortisol, a stress hormone, and prolactin. That is why newer, more targeted peptides were made. It is not an approved drug. In rats, Bowers showed in 1991 that it releases growth hormone by acting on both the brain and the pituitary gland. It did not use the usual growth hormone signal or the opiate system. Scientists found the switch itself, the growth hormone secretagogue receptor, in 1996. In rats and pigs, ipamorelin released about as much growth hormone as GHRP-6 while hitting fewer other targets.
How does GHRP-6 work?
It switches on the ghrelin receptor. That raises growth hormone and makes you hungry.
What have studies in people found about GHRP-6?
GHRP-6 has been given to people in published studies since 1990. All of them are small tests in healthy volunteers that measured hormone levels over a few hours. The longest anyone was on it was 34 hours. No study has measured muscle, fat, strength, recovery or healing, and none is registered.
- Healthy men, 1990, 18 men, a dose test by vein: they got 0.1, 0.3 or 1.0 micrograms per kg. Peak growth hormone was 1.2 on a dummy, then 7.6, 16.5 and 68.7 micrograms per litre as the dose went up. A small dose given with GHRH, the body's own growth hormone release signal, released more than either alone. Prolactin and cortisol about doubled, but only at the top dose. Two other pituitary hormones, LH and TSH, did not change in the first hour. No side effects or lab problems were seen.
- Swallowed, 1992, five healthy men and nine short children: the men took 100 and 300 micrograms per kg by mouth, and growth hormone peaked 63 and 202 times above where it started. By mouth it worked at about 0.3 percent of the strength of the same dose in a vein. Half of it was gone from the blood in 20 minutes, either way. The nine children, who were short of growth hormone to different degrees, took 300 micrograms per kg by mouth. Four responded like the adults, three had low but measurable responses, and two had none.
- Blood sugar with growth hormone blocked, 2001, 10 healthy lean men: nobody knew who got GHRP-6 and who got a dummy. With the growth hormone receptor blocked by the drug pegvisomant, and the men not fasting, GHRP-6 at 1 microgram per kg raised insulin from 10.3 to 81.3 mU/L and blood sugar from 4.2 to 6.0 mmol/L. Free fatty acids fell fast. None of this happened when the men were fasting, or without the blocker.
- A 34-hour drip, 1993, nine healthy young men: GHRP-6 or salt water ran into a vein for 34 hours. Total growth hormone roughly doubled (2,908 against 1,374 in the study's units). Peak pulses rose from 8.4 to 15.2 micrograms per litre, and IGF-1 rose from 252 to 312 micrograms per litre. The number of pulses did not change. But by the end, the body was answering less. A later dose of GHRP-6 gave a smaller rise, and TSH and prolactin also rose less when their own trigger was given. TSH was lower during the drip. That is early tolerance, measured in people.
- Overnight, 1995, healthy men: four 50 microgram shots into a vein across one night, against a dummy on another night. Growth hormone was 15.4 against 5.5 ng/mL, ACTH (the signal that drives cortisol) 21.0 against 16.6 pg/mL, and cortisol 56.0 against 25.2 ng/mL. Light sleep rose from 245.4 to 270.1 minutes, and deep sleep did not change. GHRH, the body's own release signal, lowers cortisol. GHRP-6 raised it.
What this does not tell you: Every study is a short hormone test, most in fewer than 20 healthy young men, and the result is always a level in the blood. Nobody has taken GHRP-6 for a week, let alone the months people use it for. In the one long drip, the body's response to a later dose had already shrunk by 34 hours. No study in people has measured lean mass, fat, strength, injury healing or any health result. GHRP-6 is mainly sold for boosting appetite, and that idea comes from how it acts on its receptor and from animal work. No study of food intake in people on GHRP-6 was found, so how big that effect is in a person is not known. Every human dose on record went into a vein or was swallowed, not the shot under the skin people use. The rises in cortisol and prolactin are human findings, and they grow with the dose. No trial is registered anywhere.
What do people who took 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.
- Appetite is the defining topic. It is named as one of the strongest hunger inducers people know of, with accounts of eating becoming difficult to control during a deliberate bulk, and it is described as the wrong choice for anyone trying to lose fat.
- That effect is not universal, which is itself a pattern. People describe taking large amounts and getting no hunger at all, and others describe only slight hunger at a few hundred micrograms, so the response people report varies more than the reputation suggests.
- Doses described include around 100 mcg up to three times a day and single amounts of several hundred micrograms. A microdosing approach, small amounts spread several times through the day, is discussed as a way of limiting the side effects rather than as a way of getting more from it.
- Negatives beyond hunger include a low blood sugar feeling, with lightheadedness and weakness, that people report without matching low sugar readings, swelling and cramping, and the general point that this type raises cortisol and prolactin more than the more targeted growth hormone peptides.
- A recurring technical objection in these threads is that the growth hormone spike is short lived, on the order of hours, and that this is not long enough to raise IGF-1 in proportion, which people use to explain why results feel smaller than expected.
- Vendor threads asking whether a particular source is genuine are a whole category of their own, and underdosed or misidentified product is the usual explanation offered when someone reports nothing at all.

The state of the research
The useful question about GHRP-6 is not why there are so few studies. It is why the studies stopped around 2001. They stopped because the compound had done its job.
GHRP-6 was a research tool before it was a product. Bowers and his team used it to show that growth hormone could be released through a route that was neither GHRH nor the opioid system. That meant a receptor nobody had found yet. The receptor was found in 1996, and the body's own key for it, ghrelin, in 1999. GHRP-6 was the key that opened the lock. Once the lock was open, drug companies moved to molecules they could own, take by mouth and dose daily. GHRP-6 could be none of those. Its recipe had been public since the 1980s, and as a peptide it needs a shot. It also had two drawbacks that the human studies above record rather than hide. It raises cortisol and prolactin at higher doses, and it drives appetite hard. The next generation, ipamorelin among them, was built to be cleaner. The side-by-side lab work cited on this page shows ipamorelin matching it for growth hormone release while being cleaner.
So the thin record in people is not a bad result, and it is not the kind of funding gap that surrounds a healing peptide nobody can patent. It is a choice made twenty-five years ago by companies that had something better to sell. The research record shows a string of experiments that answered their questions and then ended.
What took the place of drug development was people dosing themselves. A 2026 review in Frontiers in Endocrinology describes it directly. GHRP-6 shows up in online dosing plans next to sermorelin, CJC-1295, ipamorelin, hexarelin, AOD9604 and IGF-1 LR3, sold as research compounds. The authors sort them by evidence, from the kind of data regulators accept down to no human studies at all. The side effects they list for the group are the ones the 1990s studies measured: raised prolactin and cortisol, appetite change and unstable blood sugar. They add fluid retention, muscle aches and injection site reactions. That is an unusual spot to be in. How GHRP-6 acts in the human body is well described, in a handful of careful papers, and almost nothing that is claimed for it now was measured in any of them.

The studies we cite
- Study in people1990Growth hormone (GH)-releasing peptide stimulates GH release in normal men and acts synergistically with GH-releasing hormone.
The first clean human demonstration that this peptide releases growth hormone, and it does. 18 healthy men got GHRP-6 into a vein at three dose levels. Growth hormone peaked far higher than on the dummy and climbed steeply with dose. At half doses it worked with the natural releasing hormone to do more than either alone. Prolactin and cortisol roughly doubled, but only at the top dose. Two other pituitary hormones did not move. Nothing went wrong clinically. This measures a hormone in blood, not a health outcome.
18 normal men given GHRP-6 at 0.1, 0.3 and 1.0 micrograms per kilogram intravenously. Mean peak serum GH was 1.2 on placebo and 7.6, 16.5 and 68.7 micrograms per litre across doses, and submaximal doses combined with GHRH released GH synergistically. Prolactin and cortisol rose about twofold above basal only at the top dose; LH and TSH were unchanged over the first hour. No adverse clinical effects or laboratory abnormalities.
- Study in people1992The growth hormone-releasing activity of a synthetic hexapeptide in normal men and short statured children after oral administration.
Swallowing it works, but almost none of it gets through. Five healthy men took GHRP-6 by mouth at two doses and growth hormone shot up many times over. The swallowed route delivered roughly a three hundredth of what the same dose gave by injection. The body cleared half of it in about twenty minutes either way. Nine short children got the higher oral dose and split three ways: four responded like the adults, three weakly, and two not at all. This is a hormone reading, not growth.
Five normal men given 100 and 300 micrograms per kilogram orally reached peak GH 63-fold and 202-fold above baseline; oral activity was calculated at about 0.3 percent of intravenous, with a 20-minute serum half-life and a 2.5 litre distribution volume by both routes. Nine short-statured children given 300 micrograms per kilogram orally split three ways: four responded like the adults, three were low but measurable and two were undetectable.
- Study in people1993Effects of a prolonged growth hormone (GH)-releasing peptide infusion on pulsatile GH secretion in normal men.
The longest anyone has been kept on this peptide, and the response was already fading by the end. Nine healthy young men had GHRP-6 or salt water dripped in for thirty-four hours. Total growth hormone output roughly doubled and IGF-1 rose modestly. The natural pulse pattern did not change. By the end the pituitary was answering less: a later dose of GHRP-6 produced a smaller rise, and two other pituitary hormones also responded less to their own trigger. That is the tolerance problem, measured directly, in people.
Nine healthy young men infused with GHRP-6 or saline for 34 hours, the longest published human exposure. Integrated GH concentration rose to 2,908 against 1,374 micrograms x min per litre and IGF-1 from 252 to 312 micrograms per litre, with no change in GH pulse frequency or interpulse concentration. Partial desensitization was visible by the end: the GH response to a later GHRP-6 bolus and the TSH and prolactin responses to TRH were all smaller, and baseline TSH was lower.
- Study in people1995Growth hormone-releasing peptide-6 stimulates sleep, growth hormone, ACTH and cortisol release in normal man.
This is where the cortisol worry about GHRP-6 comes from, and it is a human measurement. Healthy men were given four small injections across one night, against a dummy on another. Growth hormone roughly tripled, and so did cortisol, with the stress hormone that drives it rising too. Light sleep gained about twenty-five minutes and deep slow-wave sleep did not change. The natural releasing hormone does the opposite to cortisol. That difference is the reason this peptide gets flagged where the other one does not.
Four 50 microgram intravenous boluses across a night against placebo in normal men. GH 15.4 against 5.5 ng/mL, ACTH 21.0 against 16.6 pg/mL and cortisol 56.0 against 25.2 ng/mL, all p<0.02. Stage 2 sleep rose from 245.4 to 270.1 minutes; slow-wave sleep did not change. The adrenal effect runs opposite to GHRH, which blunts cortisol, and is the human basis for the cortisol concern about this peptide.
- Study in people2001Blockade of the growth hormone (GH) receptor unmasks rapid GH-releasing peptide-6-mediated tissue-specific insulin resistance.
Block the growth hormone receptor and this peptide turns out to push blood sugar directly. 10 healthy lean men were studied, and nobody involved knew who got what. With the receptor blocked by a drug, and the men not fasting, GHRP-6 sent insulin up roughly eightfold and blood sugar up noticeably. Free fatty acids fell. The effect vanished when the men were fasting and when the blocker was absent. The authors read that as the peptide acting on the gut, liver and pancreas directly.
10 healthy non-obese men, double-blind and placebo-controlled. With the GH receptor blocked by pegvisomant in the non-fasting state, GHRP-6 at 1 microgram per kilogram raised insulin from 10.3 to 81.3 mU/L (P<0.001) and glucose from 4.2 to 6.0 mmol/L (P<0.05), with free fatty acids falling. The effect did not appear during fasting or without the blocker, which the authors read as a direct non-pituitary action on the gastro-entero-hepatic axis.
