Patients with a growth hormone deficiency, especially those HIV-positive, commonly take Tesamorelin, a peptide that stimulates the production of GH.
In recent years Tesamorelin commonly known as Egrifta has also gained favor due to its benefits in promoting healing and muscular development. Throughout this review, we’ll do our best to explain what Tesamorelin is, how it works, and the main advantages it offers. we’ll also describe a typical cycle of its therapeutic usage and go into further detail on how the peptide is usually dosed.
Tesamorelin: What Is It?
Growth hormone-releasing hormone (GHRH) is secreted by the hypothalamus, the brain region responsible for linking the endocrine and neurological systems. The anterior pituitary gland responds to this hormone by producing growth hormone (GH).
Tesamorelin acetate, a synthetic peptide consisting of 44 Amino Acids, is structurally and functionally similar to growth hormone-releasing hormone (GHRH).
Although Tesamorelin peptide and growth hormone-releasing hormone (GHRH) have many structural and functional similarities, Tesamorelin differs from GHRH in its N-terminal region due to a small change made to increase stability and pharmacodynamics.
How Does Tesamorelin Work?
In the same way, as an endogenous hormone would, Tesamorelin has a particular mechanism of action that affects just a few organs. Therefore, it has a highly targeted method of action.
Specifically, it binds to GHRHr in the anterior pituitary, which is responsible for releasing growth hormone. The pituitary’s somatotrophic cells are activated to produce and release growth hormone (GH) in response to this binding.
Cell types other than adipocytes (fat cells), hepatocytes (liver cells), myocytes (muscle cells), and osteoblasts (bone cells) are the primary targets of growth hormone (GH). A negative feedback mechanism is activated to keep Tesamorelin’s growth hormone (GH) release generated within predetermined parameters. Tesamorelin acetate keeps the Hypothalamus and pituitary gland in sync by naturally stimulating growth hormone production.
What Are The Benefits of Using Tesamorelin Peptide?
Tesamorelin’s principal function is to elevate GH concentrations in the blood. The Tesamorelin therapy’s additional possible advantages follow logically.
As was previously mentioned, lipodystrophy is a common side effect of HIV treatment and antiretroviral medications. It may mean either a reduction of average body fat or an abnormal accumulation of fat in certain body parts, typically the abdominal region.
Clinical studies have demonstrated that patients with HIV-associated lipodystrophy lose VAT (visceral adipose tissue) significantly. Additionally, Tesamorelin acetate enhanced body composition measurements by successfully decreasing trunk fat, waist circumference, and waist-to-hip ratio.
Carotid intima-media thickness is also decreased by this peptide (cIMT). Therefore, it slows the worsening of atherosclerotic vascular disease in the carotid arteries. Researchers might use these potential gains to support a causal relationship between Tesamorelin treatment and a lower risk of cardiovascular illnesses.
Serum levels of Insulin-like growth factor 1 are decreased in patients with lipodystrophy (IGF-1). When Tesamorelin peptide is injected into a patient, hepatocytes produce insulin-like growth factor-1 (IGF-1).
Tesamorelin induces lipolysis, which in turn lowers blood levels of cholesterol and triglycerides. Therefore, this treatment resulted in better lipid profiles for those who received it.
Tesamorelin was also shown to improve the cognitive abilities of those over 60, putting off the inevitable loss in brain function that comes with advancing age. It reduces Myo-inositol (MI), an osmolyte linked to the start of Alzheimer’s disease in younger subjects.
When is Tesamorelin Peptide Appropriate To Take?
Patients with HIV-associated lipodystrophy should use Tesamorelin to decrease fat accumulation around the abdominal area. Clinical studies indicated a reduction in abdominal and deep belly fat in those who did not have HIV.
As Tesamorelin peptide treatment stimulates the pituitary gland to secrete growth hormone, it might benefit those whose blood GH levels are below average.
A Researcher’s Guide To Tesamorelin
Tesamorelin injection is provided as a powder that must be reconstituted with the accompanying liquid. Researchers should also check the clarity of the peptide liquid. Discard the peptide immediately if you see any cloudiness or colored particles.
Please don’t wait to use it once you’ve mixed the correct dose. After the injection has been prepared, researchers should not store it. Tesamorelin injections are most often administered subcutaneously. Under the skin of the stomach or below the belly button is the most usual site of injection.
You must ensure that the injection location is entirely healthy and unblemished. In addition, you should always use a fresh syringe. Experts should only use each Tesamorelin vial (glass bottle) once. Unsealed vials must be kept in the refrigerator but must not be frozen.
Various Tesamorelin Forms
Only injectable Tesamorelin is currently available. Powdered Tesamorelin will be included in each vial and dissolved in the accompanying liquid.
This peptide is only accessible as an injectable since, in general, hormone treatments are more successful when injected as opposed to orally. In addition, after the vial’s seal has been broken, professionals shouldn’t keep it for long.
The Stacking of Tesamorelin
There has not been enough research to recommend stacking Tesamorelin with other comparable peptides. Since peptides like Ipamorelin, structurally similar to Tesamorelin acetate, haven’t been tested on humans, this is the case.
Although the method of action and advantages of Tesamorelin and Ipamorelin are similar, the latter may be stacked with the former to maximize GH production.
Adverse Reactions to Tesamorelin
The potential adverse effects of injecting this compound have been better-characterized thanks to clinical studies. In most cases, minimal symptoms are seen and subside with continued treatment.
Some side effects include sweating, redness/itching/rash at the injection site, headaches, muscular pain, nausea, vomiting, and diarrhea. Chronic symptoms include increased appetite, urination, weariness, and chest discomfort.
