Ipamorelin was identified in 1998 as the first synthetic growth hormone secretagogue to target the selective release of growth hormone as compared to GHRP. It was first developed by the pharmaceutical company Novo Nordisk under the developmental code name NNC 26-0161. Most of the studies involving ipamorelin have been conducted on animals. However, phase II clinical trials were conducted to investigate ipamorelin for post-operative ileus treatment but the trials were discontinued due to its limited efficacy.


Ipamorelin is a growth hormone-releasing peptide and a selective ghrelin agonist. It binds to ghrelin receptors that stimulate the release of immediate hormone, growth hormone-releasing hormone. This, in turn, triggers the pituitary gland to release growth hormone. Unlike other ghrelin memetics, ipamorelin has a selective activity and it doesn’t activate the body’s stress response. Further, it doesn’t influence FSH, TSH, LH and prolactin levels.

Pre-Clinical/Clinical Research

1. Diabetes

As a ghrelin mimetic, it is no surprise that it might also regulate insulin release from pancreatic cells. One study conducted in rats found that ipamorelin significantly increased insulin secretion from the pancreas in both healthy and diabetic subjects. Furthermore, it revealed that ipamorelin stimulates insulin release through calcium channels and adrenergic receptor pathways [1].

2. Bone Health

Studies conducted on animal models suggest that ipamorelin stimulates bone growth. This effect is attributed to its ability to stimulate the release of growth hormone (GH), which plays a crucial role in promoting bone health and regulating bone turnover.

In a study, scientists investigated whether the administration of ipamorelin could increase bone mineral content in female rats. Thirteen-week-old rats received ipamorelin subcutaneously for a duration of 12 weeks. The results found increased bone mineral density resulting from enhanced bone growth and improved bone dimensions [2].

Another study replicated these findings by administering various doses of ipamorelin subcutaneously three times a day to observed rats for 15 days. The results indicated a dose-dependent increase in longitudinal bone growth and body weight associated with ipamorelin. These findings suggest that this synthetic pentapeptide has the potential to enhance bone growth in children experiencing growth retardation [3].

Furthermore, an additional study examined whether ipamorelin could counteract the bone-related side effects associated with the long-term use of corticosteroids. Prolonged corticosteroid usage is known to contribute to bone loss and an elevated risk of fractures. Researchers administered ipamorelin (at a dose of 100 micrograms per kilogram) to female rats three times per day for 3 months. The results revealed a significant four-fold increase in bone formation in rats that received both corticosteroids and ipamorelin compared to those who solely received the corticosteroid drug [4].

3. Muscle Health

Like all other growth hormone secretagogues, ipamorelin is prohibited by WADA as it might enhance muscle growth and boost performance. However, there are not many documented studies to confirm this effect.

One study was conducted to investigate the influence of ipamorelin on smooth muscles in rats. In this study, gastroparesis was induced in rats through abdominal surgery, resulting in delayed gastric emptying. Subsequently, ipamorelin was administered to the subjects. The findings indicated an increase in gastric emptying among the rats that received the experimental drug compared to the control group [5].

In a clinical trial, the safety and effectiveness of ipamorelin were assessed in patients with postoperative ileus. Patients who underwent small and large bowel resection were randomly assigned to receive daily infusions of 0.03 mg/kg of ipamorelin or a placebo from day 1 to 7 following surgery. The trial revealed that this dosing regimen was well tolerated [6]. However, further research was not pursued due to the insufficient evidence of ipamorelin's efficacy in humans.

Additionally, another study found that ipamorelin has the potential to mitigate the muscle-related side effects associated with the use of corticosteroids [4].


Ipamorelin is a synthetic growth hormone secretagogue with selective activity. It stimulates the release of growth hormones with no effect on the levels of stress hormones. Research shows that ipamorelin regulates insulin levels, increases bone mineral density and enhances gastric emptying. It is banned by WADA as it has the potential to enhance athletic performance. We don’t encourage its unwarranted use and offer Ipamorelin purchase exclusively for research and educational purpose. Only buy ipamorelin if you are an authorized researcher.

What is Ipamorelin?

A synthetic peptide called ipamorelin is referred to be a growth hormone secretagogue. Its five amino acids cause the pituitary gland to release growth hormone, which is how it works. Ipamorelin binds specifically to the ghrelin receptor, resulting in a series of signaling events that stimulate the release of growth hormone. For its potential advantages, such as fostering muscle growth, boosting recovery, enhancing body composition, and even influencing bone health and cognitive function, this peptide has drawn interest in both research and therapeutic contexts. Ipamorelin should only be used with caution and under qualified medical supervision, it is crucial to remember.

Ipamorelin Research

Ipamorelin is a synthetic peptide that has attracted a lot of investigation because of its potential uses in many different industries. The main areas of ipamorelin research are examined here, along with its effects and potential benefits.

Stimulation of Growth Hormone Release:

The capacity of ipamorelin to promote the release of growth hormone (GH) is one of the main areas of research attention. The ghrelin receptor, which is present in the hypothalamus and pituitary gland, is where ipamorelin binds. This binding starts a signaling chain reaction that boosts GH secretion. In vitro and animal studies have both been used to examine the dose-response relationship of ipamorelin and its effectiveness in boosting GH release.

Muscle Growth and Performance Enhancement:

Ipamorelin has shown promise for boosting muscle development and improving athletic performance. As GH is essential for protein synthesis and muscle repair, its capacity to promote GH secretion contributes to its anabolic effects. Ipamorelin administration has been found in studies to increase muscle mass, increase muscle strength, and speed up recovery from exercise-induced muscle injury. This peptide has been researched for its possible application in the treatment of muscle degenerative diseases, enhancement of sports performance, and stimulation of muscle growth in the elderly.

Metabolic Effects and Body Composition:

Research on ipamorelin has looked at how it may affect body composition and how it may affect metabolism. According to studies, ipamorelin can increase insulin sensitivity, enhance lipid metabolism, and encourage the loss of adipose tissue. It is a topic of interest in studies on obesity, metabolic syndrome, and insulin resistance because of these metabolic advantages. Its potential therapeutic uses in modifying body weight, body fat percentage, and metabolic parameters are under investigation.

Bone Health and Regeneration:

The effects of ipamorelin on bone health and bone regeneration have also been investigated. Ipamorelin may stimulate bone mineralization, promote osteoblast activity, and maybe improve bone density, according to research. Ipamorelin's potential to improve bone regeneration and maybe lessen circumstances of bone loss has been demonstrated in studies using animal models. Further investigations are needed to determine the underlying mechanisms and potential clinical applications.

Cognitive Function:

Ipamorelin may have effects that improve cognition, according to recent studies. Its ability to enhance memory, cognitive function, and neurogenesis has been demonstrated in studies. Ipamorelin's neurological effects are partly attributable to its capacity to pass the blood-brain barrier and interact with the ghrelin receptor in the brain. Ipamorelin may be used therapeutically to treat neurological disorders and cognitive deficits, according to research.
