Tesamorelin is a peptide that triggers the secretion of growth hormone (GH) and is often prescribed to people with a deficiency of growth hormone (GH), particularly HIV patients [1]. However, it’s also risen in popularity over the last few years among the bodybuilding community for its uses in enhancing recovery and facilitating muscle growth.
In this review, I aim to give you an inside-out knowledge of what tesamorelin is, how it works, and its major benefits. Additionally, I’ll provide more information on how it’s typically dosed and reveal what a typical cycle of it looks like for therapeutic uses.

What Is Tesamorelin
The hypothalamus, a portion of the brain that establishes a link between the endocrine and nervous systems, releases a hormone called growth hormone-releasing hormone (GHRH). This hormone triggers the release of growth hormone (GH) from the anterior pituitary gland. [2]
Tesamorelin acetate, a synthetic peptide comprising 44 Amino acids, is analogous to the growth hormone-releasing hormone (GHRH) in structure and function. [3]
However, the N-terminal portion of Amino acids that give any peptide its characteristic properties is slightly modified in tesamorelin compared to growth hormone-releasing hormone (GHRH) for improved stability and pharmacodynamics.
How Does Tesamorelin Work
As tesamorelin mimics the action of a naturally occurring endogenous hormone, it also acts on specific target sites. Hence, the mechanism of action followed by tesamorelin is very specific.
Tesamorelin binds to the growth hormone-releasing hormone receptors (GHRHr) located in the anterior pituitary gland. This binding stimulates the somatotrophic cells in the pituitary gland to synthesize and secrete growth hormone (GH).
Growth hormone (GH) acts primarily on adipocytes (fat cells), hepatocytes (liver cells), myocytes (muscle cells), and osteoblasts (bone cells). [4]
To ensure the tesamorelin-induced release of growth hormone (GH) is within set limits, a negative feedback mechanism is initiated, so that serum growth hormone (GH) levels don’t overshoot.
As tesamorelin triggers the release of growth hormone (GH) naturally, it maintains homeostatic coordination between Hypothalamus and pituitary gland.
Benefits Of Tesamorelin
The primary purpose of tesamorelin is to increase the serum levels of growth hormone (GH). The other potential benefits of the tesamorelin therapy just come organically with it.
As discussed earlier, one of the major symptoms of HIV and antiretroviral medication is lipodystrophy. [5] It refers to either excessive build-up of fat in certain areas of the body, especially the abdominal region, or loss of normal body fat.
Clinical trials have shown a considerable reduction of visceral adipose tissue (VAT) in patients suffering from HIV-associated lipodystrophy.
Besides, tesamorelin also improved body composition measures by effectively reducing trunk fat, waist circumference, and waist-to-hip ratio. [6]
Tesamorelin is also seen to reduce the size of carotid-intima media size (cIMT). Hence, it reduces the progression of carotid atherosclerotic vascular disease.
These prospective benefits might help establish a link between tesamorelin therapy and reduced risk of developing cardiovascular diseases.
Patients with lipodystrophy have lower serum levels of Insulin-like growth factor 1 (IGF-1). Tesamorelin administration triggers the production of IGF-1 from the hepatocytes. [7] IGF-7, without altering blood glucose levels, carries out the process of growth and inhibits the programmed cell death mechanism.
Tesamorelin reduces the levels of cholesterol and triglycerides by carrying out the process of lipolysis. Hence, lipid profiles improved in the people who were administered tesamorelin.
Additionally, tesamorelin was also seen to enhance the cognitive capacities of individuals over 60, thereby delaying the decline in brain functioning. This is achieved as tesamorelin lowers the level of myoinositol (MI), an osmolyte that triggers the early onset of Alzheimer’s disease. [8]
Tesamorelin Usage in Bodybuilding
Tesamorelin, a Growth Hormone Releasing Hormone analog, works by stimulating the release of Growth Hormone, which in turn increases the levels of Insulin-Like Growth Factor-1 (IGF-1). It is IGF-1 that mediates the specific benefits associated with bodybuilding.
According to studies, IGF-1 promotes muscle proliferation through satellite cells, decreases muscle breakdown, and also prevents toxin-induced inflammation of muscles. If youโre specifically using Tesamorelin for bodybuilding, 1 mg of injection 90 minutes before eating is usually advised. You can use it for 5 days straight, followed by 2 days off, and repeating the cycle.
Is Tesamorelin Legal
Owing to its effectiveness in treating patients with HIV-associated lipodystrophy, FDA has approved the use of tesamorelin. But you will still need a prescription from a medical practitioner to make a legal purchase of tesamorelin.
Who Should Use Tesamorelin
Patients with HIV-associated lipodystrophy should use tesamorelin to reduce the excessive abdominal fat that has accumulated. It is imperative to mention that clinical trials showed a decrease in abdominal and deep belly fat in non-HIV individuals. [9]
Tesamorelin can also be used by people deficient in the normal serum levels of growth hormone (GH) as tesamorelin therapy induces its natural release from the pituitary gland.
How To Use Tesamorelin
Tesamorelin injection comes in powder form that needs to be mixed with a liquid that comes alongside it. Also, make sure to check on the tesamorelin liquid to see if it’s clear or not. In case of the slightest cloudiness or colored particle, you should discard them straight away.
After mixing it with the right amount of your dosage, use it straight away without any delays. Don’t store the injection after you have mixed it.
Tesamorelin is usually injected via the subcutaneous method. The most common regions of the body where it is injected are under the stomach’s skin or below the belly button.
Make sure to inject tesamorelin at different sites of the skin. Never pinch the needle at the same point twice in a row. Your doctor would educate you about the appropriate sites of administration.
You should make sure that your injection site is free of any bruises, scars, or injuries. Also, using a new syringe is a no-brainer at all!
Use each vial (glass container) of tesamorelin once only. Storing of unsealed vials should be done in the refrigerator but make sure not to freeze it.
Forms Of Tesamorelin
Tesamorelin is only available in injectable forms. Each vial will have tesamorelin in powder form that will be mixed with the liquid that comes along.
The main reason why tesamorelin is only available in injectable forms is that hormone therapies are generally more effective when injected than oral intake. [10]
Besides, tesamorelin is not advisable to be stored after it is unsealed. This can be correlated to why it is not available in any of the oral forms.
Tesamorelin Dosage
Since tesamorelin can be used for multiple reasons, the dosage guidelines differ for each purpose of intake.
The best way to decide your dosage is to consult a doctor who would give you precise guidelines considering your medical condition, body size, age, etc.
To meet growth hormone (GH) deficiency in your children, consult your doctor for an effective prescription.
Tesamorelin Cycle
The clinical trials observed across various groups of patients gave us considerable information about cycling guidelines.
Patients with HIV-associated lipodystrophy were seen to experience a reduction in Visceral adipose tissue (VAT) but only as long as tesamorelin administration continued.
Once the tesamorelin injection stopped and the placebo was introduced, irregular fat distribution across several body regions was again seen.
Thus, experts conclude that tesamorelin should be taken 5 days per week for 2 months followed by a month off.
Also, the ideal time to inject tesamorelin is before bed to set up a natural timer.
Tesamorelin Stacking
So far, not enough studies suggest that tesamorelin should be stacked with any other similar peptide. This is because peptides similar to tesamorelin, such as Ipamorelin, haven’t undergone human clinical trials yet.
But considering the more or less similar mechanism of action and the benefits, tesamorelin can be stacked with ipamorelin to achieve an optimum growth hormone (GH) release.
Tesamorelin Experiences
As I started to read personal experiences of people using Tesamorelin on a credible website, people had mixed opinions.
Here are some of the reviews I could find:
“Just finishing 2 months on Egrifta. 1st month is not remarkable but at the 6 weeks mark, I’m noticing a change. It seems as if the visceral fat has reduced and moving to sub-q fat. I’ve maintained the same diet, medication, and workout schedule. Just about 7 lbs. weight loss but not sure it’s the Egrifta. Will check in at the 3-month mark.”
-Brainsbelly
“I have been on Egrifta for 14 months. It took 6 months before I noticed much. I am now pleased with the results and will continue to use the product.”
-Jack
“Body aches, nausea, but it is working. Not actual weight, but reducing belly fat”
-Steve
“I have been administering Egrifta now for 2 1/2 months, with absolutely no reduction of abdominal fat. I am a thin person with my abdominal fat causing me to be unable to close the buttons and zippers of my clothing. Then I heard of Egrifta thinking it was the answer. Wrong! No results, just a painful irritated, scar tissue in my abdomen now.”
-Mad
“I began the Egrifta Injection at 2 ml per day. I began feeling the fat soften within the first week. I began the medication weighing 226.2 lbs and in less than 6 months I weighed 198.2 lbs. Then my GH1 level shot up and within 2 weeks every bit of the weight I had lost all returned plus. By the way, once you begin taking this cover-up drug, you’re on it the rest of your life, or the fat returns.”

Tesamorelin Side Effects
Human clinical trials improve our understanding of the possible side effects of tesamorelin injection. Generally, there are just mild symptoms observed which diminish after continuous administration.
Sweating, redness/itching/rashness at the injection site, muscle aches, vomiting, and diarrhea are a few of the adverse effects observed.
Increased hunger, frequent urination, a feeling of fatigue, and chest pain are some of the chronic side effects.
Where Can I Buy Tesamorelin
Tesamorelin
Tesamorelin is a Peptide that is prescribed to individuals that have too much adipose tissue around their stomach, typically those who suffer from HIV.
Certain illnesses and lifestyle choices will store fat more around the abdomen, which is actually pretty unhealthy.
Losing weight will mostly be determined by training and diet, however, Tesamorelin combined with professional medical advice can help you lose a lot of fat.
Tesamoreline is a GHRH, so you will see an increase in plasma Growth Hormone levels. You can expect an increase in insulin-like growth factor (IGF-1) following injections, which has other benefits such as cell growth in skin and hair.

Tesamorelin vs. Other Peptides
Tesamorelin vs Ipamorelin
What distinguishes both the peptides is the human clinical trials. Ipamorelin is yet to undergo human-based research. Although the result of both the peptides is more or less similar, there still exist differences in structure and mechanism of action.
Ipamorelin is just made up of 5 Amino acids. Besides, it also puts a halt to the negative feedback mechanism by inhibiting somatostatin.
Tesamorelin vs Sermorelin
Tesamorelin is better than sermorelin as it has a longer half-life and stimulates the pulsatile release of growth hormone (GH) from the somatotrophic cells.
Is Tesamorelin legit?
The conclusive results from human-based clinical trials of tesamorelin distinguish it from other similar peptides from all dimensions.
I would recommend tesamorelin at any time of the day owing to its widespread benefits to HIV patients and meeting the deficiency of serum levels of growth hormone (GH).
I believe a bit more research on tesamorelin linked with minimizing the development of cardiovascular diseases can make it more acceptable in the eyes of the potential audience.
