Common use ranges
From user guides and clinic write-ups. No drug label exists, and no study has tested these amounts in people. No drug label. Only one comparison guide gives amounts: 100 to 200 mcg a shot, 2 to 3 times a day.
Sources disagree, or there are very few. The amounts below come from a small number of guides, and they do not line up well. Treat every number on this page as uncertain, and check each source yourself.
- Half-life
- about 76 minutes in rats
- How it is taken
- subcutaneous injection
- How long people use it
- Not stated by the source.
- Mixing used for the units
- 5 mg vial + 2 mL water. 1 unit on a U-100 insulin syringe = 25 mcg.
Pick your vial size and how much water you add. The units below change to match.
5 mg vial + 2 mL water: 1 unit = 25 mcg

Amounts given to people in studies
How it was given: into a vein for the one-time tests, under the skin for the one long study
The only repeated-use study used 1.5 micrograms per kilogram under the skin, twice a day.
Amounts given to animals in studies
Read this first. In the only 16-week study the growth hormone response dulled by week 4 and IGF-1 never moved. Swallowed hexarelin barely works, about 0.3 percent gets through.

Proof grade: Small human studies. Only small or uncontrolled human studies. Amounts are quoted as each study reported them. Where the abstract does not state an amount, the row says so.
| Study | Who was studied | Amount given, as reported | Route | How often | How long | What the authors reported |
|---|---|---|---|---|---|---|
| PMID 9404449Arvat et al, Clin Endocrinol 1997 | Human, 6 healthy men aged 24 to 30 | 0.25, 0.5 and 2.0 mcgrams/kg | Into a vein | One time per dose level | Single doses | Growth hormone rose more as the amount rose |
| PMID 9156035Loche et al, Clin Endocrinol 1997 | Human, 8 healthy men aged 21 to 33 | 2 mcgrams/kg | Injection, route not in abstract | One time, morning and again at night | Single doses | Peak growth hormone about the same awake and asleep |
| PMID 7962341Arvat et al, J Clin Endocrinol Metab 1994 | Human, 13 young and 16 elderly men | 2 mcgrams/kg | Into a vein | One time per session | Single doses | Response was much weaker in the elderly, arginine restored it |
| PMID 9253314Ghigo et al, J Clin Endocrinol Metab 1997 | Human, 12 healthy adults plus Cushing's patients | 2.0 mcgrams/kg | Into a vein | One time | Single dose | Also pushed up ACTH and cortisol, like CRH does |
| PMID 11322491Broglio et al, Endocrine 2001 | Human, 7 healthy adults, 7 growth-hormone-deficient, 12 with an enlarged weak heart | 2.0 mcgrams/kg | Into a vein | One time | Single dose, followed 60 minutes | Squeezed the heart harder in the first two groups, no blood pressure change |
| PMID 9589671Rahim et al, J Clin Endocrinol Metab 1998 | Human, adults (n not in abstract) | 1.5 mcgrams/kg | Under the skin | Twice a day | 16 weeks, plus 4 weeks off | The growth hormone response dulled part way and came back after stopping, IGF-1 never moved |
| PMID 10611139Roumi et al, Drug Metab Dispos 2000 | Rat, male Sprague-Dawley | 5 mcgrams/kg into a vein, 5, 10 and 50 mcgrams/kg under the skin | Into a vein, and under the skin | One time | Single doses | Clearing half of it took 76 minutes, 64% got in from a skin shot |
| PMID 11578108Westberg et al, J Pharm Pharmacol 2001 | Human, plus rat gut tissue | Not stated in the abstract | By mouth | One time | Single dose | Only 0.3% of a swallowed dose worked, gut trypsin breaks it up |
How to read the study numbers
- One study, one group. Each figure is what one team chose for its own participants or animals.
- Route matters. An amount given into a vein (IV) is not the same as the same amount under the skin, in the nose or by mouth.
- Animals are not small people. An animal amount is shown as the study gave it. It is not a human amount.
- Short studies. Many studies ran days or weeks. They do not show what happens over longer use.
Common questions
What amounts of Hexarelin were used in human studies?
In the studies listed here, people were given from 0.25 micrograms per kilogram, one time, into a vein up to 2 micrograms per kilogram, one time, into a vein. The amount used most often was 2 micrograms per kilogram, one time, into a vein. These are what study teams chose for their participants under supervision.
Where do these Hexarelin numbers come from?
From 8 published studies, each linked to its PubMed or ClinicalTrials.gov record. Every figure was checked against the study abstract or its open full text. Proof grade: Small human studies.
How long does Hexarelin stay in the body?
Its half-life is about 76 minutes in rats, measured in animals, not people. Half-life is how long it takes for half of a dose to leave the blood. The effect can last longer than that.
Is this a recommendation for how much Hexarelin to use?
No. This page shows the amounts reported by drug labels, clinics and users, next to what researchers gave in studies. It is not medical advice and not a recommendation for anyone. Talk to a licensed clinician before using any of it.
