Alexamorelin
Alexamorelin is a hexarelin-derived synthetic growth hormone releasing peptide studied mainly in preclinical animal models. Research has focused on both its GH-releasing activity and its potential prokinetic effects on gastrointestinal motility, suggesting activity on ghrelin receptors outside the pituitary. Human data remains very limited compared to other GHRPs, so its effects, dosing, and safety profile in humans are not well established. It is best considered an emerging research compound rather than a well-characterized peptide.
Reported benefits
- GH secretion observed in preclinical research
- Studied for gastrointestinal motility support
- Potential recovery support (largely theoretical)
How it works
Alexamorelin is reported to act on the growth hormone secretagogue receptor (GHS-R1a) to stimulate GH secretion, similar to its parent compound hexarelin. Preclinical research has also examined ghrelin-receptor activity in gastrointestinal tissue, proposed as the basis for studied effects on gut motility.

Common questions
What is Alexamorelin used for?
Alexamorelin is a hexarelin-derived synthetic growth hormone releasing peptide studied mainly in preclinical animal models. Research has focused on both its GH-releasing activity and its potential prokinetic effects on gastrointestinal motility, suggesting activity on ghrelin receptors outside the pituitary. Human data remains very limited compared to other GHRPs, so its effects, dosing, and safety profile in humans are not well established. It is best considered an emerging research compound rather than a well-characterized peptide. Reported benefits include gh secretion observed in preclinical research, studied for gastrointestinal motility support, potential recovery support (largely theoretical).
What is a typical Alexamorelin dose?
Reported ranges run 50-150 mcg. A low protocol is 50 mcg once daily, and a high protocol is 150 mcg twice daily. This is reference information, not a dosing recommendation.
What is the half life of Alexamorelin?
Unknown (limited pharmacokinetic data, primarily from animal studies). That is what sets the dosing frequency, and it is why the timing guidance is ~30 min before bed, empty stomach.
How is Alexamorelin administered?
Subcutaneous: into fat, under the skin. Research use is subcutaneous injection; most available data comes from animal studies
How long is a Alexamorelin cycle?
8 weeks on, followed by 4 weeks off. Cycle conventions are borrowed from other GHRPs; peptide-specific cycling data is absent
What are the side effects of Alexamorelin?
Reported side effects include limited human safety data, theoretical ghrp-class effects such as hunger and water retention, injection-site irritation. Evidence level for this compound is emerging research.
