Sermorelin is a synthetic growth hormone (GH) secretagogue that has been developed to stimulate the natural production of human growth hormone (HGH) in the pituitary gland. Its clinical applications include the diagnosis and treatment of growth hormone deficiency in children. It is often times called the growth hormone Sermorelin.

Originally developed in the United States during the early 1980s, Sermorelin played a crucial role in aiding researchers in the identification of potential growth hormone deficiencies within the pituitary gland. This breakthrough paved the way for subsequent advances in the field. Recognizing the country’s potential, the U.S. In 1997, the Food and Drug Administration (FDA) approved Sermorelin for the detection and treatment of GH deficiency in children. [R]

Certain studies suggest that Sermorelin has certain effects on tissue regeneration and it might include myocardial infarct scar.

Sermorelin has undergone a number of laboratory tests to further understand its effect on the human body. Buy Sermorelin for laboratory and research use.

Sermorelin Product Details

Sermorelin is a synthetic growth hormone-releasing hormone (GHRH) analog that is derived from the first 29 amino acids of the GHRH protein. With a molecular weight of 3357.9 g/mol, Sermorelin exhibits a remarkably short half-life of approximately 11-12 minutes, distinguishing it from other peptides commonly used in therapeutic applications.

Extensive research has shed light on several potential effects of Sermorelin including some physiological feedback mechanisms. In GH-deficient children, it has shown promise in potentially increasing growth rates and might even lead to endocrine and orexigenic actions. [R]

Additionally, in test subjects with reduced insulin-like growth factor 1 (IGF-1) levels, Sermorelin may potentially raise GH and IGF-1 levels. For those research groups that assess growth hormone secretion, some of them suggest that Sermorelin holds the potential to enhance various aspects, including the increase of lean body mass, improvement of insulin sensitivity, enhancement of overall well-being, and boosting of libido.

Furthermore, in GH-deficient rats, Sermorelin has demonstrated the potential to increase testosterone secretion. These findings underline the diverse therapeutic possibilities and the significant impact Sermorelin may have in various clinical contexts.

Potential Benefits of Sermorelin

Sermorelin and Height

Clinical trials have shown that Sermorelin administration can accelerate growth in GH-deficient children. Daily subcutaneous administration of Sermorelin led to increased height velocity in these children, without any adverse changes in biochemical or hormone analyses. Another study discovered that twice-daily Sermorelin administration promoted linear growth in short children who did not have insufficient GH, with a sustained improvement in height velocity over a 12-month period of treatment. However, changes in glucose homeostasis were observed during the treatment period in this study. [R][R]

Sermorelin and IGF-1

Research has demonstrated that twice-daily Sermorelin treatment can potentially increase IGF-1 levels in both young and elderly test subjects. Interestingly, in elderly clinical participants, IGF-1 levels remained elevated even two weeks after discontinuing Sermorelin treatment. However, another clinical trial using once-nightly administration of Sermorelin in healthy elderly men did not significantly increase IGF-1 levels. These results suggest that the timing and frequency of Sermorelin treatment play a crucial role in determining its impact on IGF-1 levels. [R][R]

Sermorelin and GH

Studies have shown that high-dose Sermorelin treatment can elevate growth hormone levels among test subjetcs. In elderly models, Sermorelin effectively increased mean 24-hour growth hormone levels, with no significant difference compared to the younger age group. These findings indicate that Sermorelin can successfully stimulate growth hormone secretion similar to endogenous GHRH. [R]

Additionally, Sermorelin treatment was also found to increase other hormones such as prolactin, follicle-stimulating hormone, and luteinizing hormone. [R]

Sermorelin and Muscle Endurance

A clinical study involving male laboratory subjects demonstrated the potential benefits of once-nightly administration of Sermorelin on muscle endurance. The study showed a significant improvement in abdominal crunch performance, which is a test of muscle endurance, after Sermorelin treatment. These findings suggest that Sermorelin may have a positive impact on muscle function and endurance in aging participants. [R]

Sermorelin and Libido

In the clinical trial, Sermorelin treatment for 4 months also demonstrated the potential to increase libido (sexual drive) in male clinical models, similar to PT-141. Interestingly, the improved libido was not associated with changes in serum androgens such as testosterone, DHT, and sex hormone-binding globulin. The reasons for these gender differences and the mechanisms involved require further investigation. [R]

Sermorelin and Testosterone

Studies in GH-deficient rats have shown that Sermorelin therapy can increase testosterone secretion and enhance testicular luteinizing hormone (LH) receptors. However, clinical trials with Sermorelin in human subjects did not find any significant effects on testosterone levels. This indicates that more research is needed to fully understand and confirm the impact of Sermorelin on testosterone levels in test subjects. [R]

Sermorelin and Lean Body Mass

Sermorelin treatment has shown the potential to increase lean body mass in male mammals. In a clinical trial involving 19 participants of both genders, male subjects experienced a significant gain of 1 kg in lean body mass after 4 months of Sermorelin treatment. The only adverse side effect observed was transient hyperlipidemia, which resolved by the end of the study. No other adverse effects were reported. [R]

Sermorelin and Heart Health

Animal studies have suggested that Sermorelin administration can have positive effects on heart health. In a study involving pigs, Sermorelin was found to reduce remodeling following a heart attack, decrease cell death in cardiomyocytes, and promote the growth of blood cells in damaged tissue. Similarly, cell-based studies have indicated that treatment with GHRH agonists, like Sermorelin, may reduce inflammatory responses after a heart attack, potentially improving healing and cardiac remodeling mechanisms. [R][R]

How It Works

Sermorelin operates by stimulating the growth hormone-releasing hormone (GHRH) through the hypothalamic-pituitary-somatotropic axis, setting it apart from other growth hormone secretagogues such as Ipamorelin, which exert their effects via the ghrelin/growth hormone secretagogue receptor (GHS-R) pathway.

GHRH is primarily synthesized in the hypothalamus and serves a vital role in potentially increasing the secretion of growth hormone (GH). GH, in turn, offers a range of potential benefits, including the ability to enhance bone density, promote muscle mass development, reduce body fat, and facilitate growth in adolescents and children. Additionally, GH helps maintain the normal structure and metabolism of the body. These interactions highlight the significance of Sermorelin’s mechanism of action and the potential positive impact it can have on various aspects of health.
