Objective: In man, new synthetic peptides such as hexarelin have been shown to have a potent and dose dependent GH releasing activity. Furthermore, a significant PRL releasing activity has also been demonstrated, but this has been investigated in less detail. We have therefore evaluated the effect of hexarelin on PRL and GH secretion in patients with active acromegaly or pathological hyperprolactinaemia.
Measurements: GH and PRL levels were evaluated every 15 minutes for 2 hours after hexarelin or placebo. Both hormones were measured using commercial IRMA kits. Basal IGF-I was measured in all subjects using an RIA following acid-ethanol extraction.
Conclusions: Our data show that the PRL releasing effect of hexarelin is preserved in acromegaly but lost in pathological hyperprolactinaemia. In contrast with acromegaly, the GH releasing effect of hexarelin is also blunted in hyperprolactinaemic patients. These data demonstrate that patients with pathological hyperprolactinaemia are partially refractory to the activity of hexarelin.
Hexarelin is a synthetically developed growth hormone receptor (GHR) that is known for its ability to efficiently activate the growth hormone secretagogue receptor (GHSR) in a fashion similar to that of the naturally occurring peptide, ghrelin. However, when comparing hexarelin to ghrelin, hexarelin is the more stable and potent compound of the two.
Previous studies show that ghrelin can be administered to improve cardiovascular functioning in terms of cardiac output, ejection fraction, and exercise capacity in rats experiencing chronic heart failure. While ghrelin is successful in treating heart failure it is considered a highly unstable compound, hexarelin on the other hand has shown promise in treating cardiovascular disease on the same level as ghrelin, however, hexarelin is far more stable and much more effective.
In a study conducted by Mao et. Al, hexarelin was administered to various animal subjects in order to observe its effects on apoptosis, ischemia-reperfusion injury, myocardial infarction, cardiac fibrosis, and atherosclerosis.
Neonatal rats were treated with varying doses of hexarelin to examine how the peptide is capable of inhibiting apoptosis in cardiomyocytes. The results of this portion of the study found that hexarelin treatment decreased levels of apoptosis induced by angiotensin II as well as doxorubicin-induced apoptosis. Additionally, it helped to increase the viability of the myocytes and promoted the survival of cardiomyocytes and cardiac epithelial cells.
Zucker rats were treated with 1 micromol/L of hexarelin and then subjected to ischemia for 30 minutes and reperfused for 120 minutes. It was found that with this dose of hexarelin for 30 days the heart damage caused by the ischemia was significantly decreased. The hexarelin treatment promoted cell survival, decreased apoptosis of the cardiomyocytes, and preserved the electrical properties of the myocytes. Furthermore, results showed that in rats treated with hexarelin there was improvement in left ventricle pressure as well as more protection against ischemia and angiotensin II secretion.
Male rats underwent ligation of the coronary artery. Four weeks after the procedure the rats were treated with 100 micrograms/kg/day of hexarelin for two weeks. The results of this portion of the study were very straightforward, it was found that this method of treatment led to a decrease in peripheral resistance, and increases in stroke volume, cardiac output, and cardiac index.
Cardiac fibrosis occurs when there is too much collagen, types I and II, and proteins being deposited throughout the cardiac muscle. Treatment with hexarelin in hypertensive rats over 5 weeks led to a decrease in cardiac fibrosis via a decrease in collagen deposition, and hydroxyproline content in the myocytes. Furthermore, hexarelin treatment decreased blood pressure, left ventricular hypertrophy, and diastolic dystrophy. Hexarelin also decreased the upregulation of TGF-beta expression and secretion caused by angiotensin II.
Atherosclerosis is caused by increased levels of triglycerides and cholesterol. Sprauge-Dawley rats experiencing atherosclerosis were treated with hexarelin. Results found that the formation of atherosclerotic plaques was prohibited. Additionally, hexarelin treatment was seen to lower the ratio of HDLP cholesterol to LDL cholesterol and increase levels of nitric oxide and the mRNA expression of endothelial nitric oxide synthase. While there was little to no change in the triglyceride levels, plasma cholesterol was reduced. This led researchers to conclude that hexarelin is capable of treating atherosclerosis through the regulation of various cholesterol levels ( ).
Examorelin (INN) (developmental code names EP-23905, MF-6003), also known as hexarelin, is a potent, synthetic, peptidic, orally-active, centrally-penetrant, and highly selective agonist of the ghrelin/growth hormone secretagogue receptor (GHSR) and a growth hormone secretagogue which was developed by Mediolanum Farmaceutici. It is a hexapeptide with the amino acid sequence His-D-2-methyl-Trp-Ala-Trp-D-Phe-Lys-NH2 which was derived from GHRP-6. These GH-releasing peptides have no sequence similarity to ghrelin, but mimic ghrelin by acting as agonists at the ghrelin receptor.
The availability of growth hormone secretagogue receptor (GHS-R1a) in the peripheral organs like the heart, bones, adrenal gland, and digestive tract means that hexarelin can also trigger a localized effect. Particularly, the binding of hexarelin with cardiac receptors called CD36 (3) is a growing area of research.
As hexarelin binds to the CD36 receptors located on blood cells, it greatly improves cardiovascular functioning by maintaining the normal cardiac parameters such as left ventricular ejection fraction (LVEF), cardiac output, stroke volume, and decreasing the peripheral resistance in the blood vessels (3).
Owing to the tremendous effects observed in cardiovascular health, anybody with a past history of cardiovascular diseases such as myocardial infarctions and arrhythmias can take hexarelin. This is because hexarelin is seen to minimize fibrous accumulation.
Just like most other peptides, hexarelin is also available as a dry powder in the vial (a glass container). Once you have purchased hexarelin, you need to mix it with bacteriostatic water, depending on your dosage guidelines.
You need to inject it subcutaneously, inserting the needle just under the skin and not in the muscle. Generally, the abdominal area is seen as an ideal place to inject it. Subcutaneous injection of hexarelin is seen to achieve maximum effects on the user.
200mcg-300mcg is advised to be the daily intake of an individual (4). The optimal results are often seen in people who administer hexarelin subcutaneously 2-3 times a day, with each dose comprising approximately 100mcg.
But considering the similar dosage guidelines and benefits that Modified GRF1-29 offers (6), such as lean muscle growth, flexible joints, strong tendons, and quicker wound healing, some companies have started selling Modified GRF 1-29 5mg and hexarelin 5mg (10mg total blend).
As discussed earlier, hexarelin influences multiple endocrine pathways, so most of its side effects (8) include higher cortisol levels, increased prolactin levels, and insulin desensitization. Low libido is also a common complaint by users of hexarelin.
While the mechanism of action and primary benefits for both peptides are quite similar, the difference arises in the secondary benefits. Ipamorelin is proven to improve bone density, while hexarelin enhances cardiovascular health.
