How Long Human Growth Hormone Lasts in Your Body

How Long Human Growth Hormone Lasts in Your Body

The body naturally produces the growth hormone. The anterior pituitary gland is situated at the base of your brain, and it secretes and synthesizes the growth hormone. The secretion of the growth hormone into your circulation system follows a pulsatile pattern that comes from the fluctuation of blood vessels. Several factors, such as physical activity, age, steroids, sleep, diet, and gender, are responsible for the instability of blood vessels.

Human growth hormone promotes several metabolic processes in body cells. The hormone affects carbohydrate, protein, mineral, and fat metabolism. The primary role of the human growth hormone is to stimulate the liver to produce Insulin-like Growth Factor (IGF-1) that encourages the production of cartilage cells. The cells have a role in bone growth, organ growth, and muscle protein synthesis.

The Control of Growth Hormone

The body does not continuously produce growth hormones. The body releases this hormone in several bursts or pulses every three to five hours. [2] The somatostatin inhibits the release of the growth hormone as well as the hypothalamus, which is the growth hormone-releasing hormone that stimulates the pituitary gland to release growth hormone.

Several other factors control the release of the growth hormone. Sleep, low glucose levels in the blood, exercise, and stress contain the rates of human growth hormone release in your body. Growth hormone levels also increase at puberty. The levels are reduced when the body realizes high levels of growth hormone or presence of insulin-like growth factors and during pregnancy.

How Long Does HGH Stay in Your System?

The length of time the human growth hormone remains in your system is not definite. Each individual is different, and people have different results after undergoing HGH therapy or consuming supplements. Also, the timeline for human growth therapy differs from an individual to another, and the results are also different. [4] The results or the length of time human growth hormone lasts in the system depend on an individual and how fast the treatment starts to work.

However, medical experts indicate that the human growth hormone has a circulating half-life of about 20 to 30 minutes. It has a biological half-life of between nine to 17 hours. People who seek human growth therapy, supplements ought to do so under the supervision of a physician throughout the treatment period. Also, consult a doctor when you want to discontinue HGH treatment. Notify your physician if you experience anything unusual during the treatment period. The medical professional will know whether to adjust the dose or not and if you need to resume the treatment.

Multiple factors determine the length of time human growth hormone stays in your system. Usually, your body secretes growth hormone from the system a few minutes after taking it. Human growth hormone can be detected in your body 72 hours after consuming the supplements or after injection into your system. Here are some factors that cause the variation of HGH:

  • Fat percentage
  • Age
  • Body mass
  • Sex
  • Overall health status and underlying medical conditions
  • Schedule of HGH injections
  • Body rate of absorption and response to HGH

Possibilities of Developing HGH Withdrawal

As long to adhere to the appropriate dose given by a medical professional, you are unlikely to experience adverse side effects. Similarly, you may not experience significant negative impact upon stopping the HGH treatment.

Athletes and bodybuilders misuse human growth hormone by taking higher than the usual doses. When these people stop taking HGH, they can experience withdrawal symptoms. The best to avoid withdrawal symptoms is to get human growth hormone supplements or injections from a professional. HGH treatment is regulated, meaning that you should not get the injections without a doctor’s prescription.

What Happens When You Stop Taking HGH?

The growth hormone levels are likely to fall again when you stop taking HGH. Typically, the levels will reduce to their previous amount. Consequently, you will experience the same feelings you had before starting the HGH treatment. Some of the symptoms you might experience when you stop HGH are similar to growth hormone deficiency signs. They may include:

  • Reduced muscle mass
  • Reduced stamina and energy
  • Psychological issues, such as anxiety and depression
  • Unusual cardia enzyme levels
  • Central adiposity

The reasons why growth hormone deficiency causes several problems is because your body requires sufficient levels of growth hormones for optimal function. [5] It does not take long for growth hormones to leave your body when the HGH levels fall due to deficiency or when you stop the treatment. As seen above, the same signs that triggered you to seek medical help for HGH treatment will start resurfacing.

Importance of Growth Hormone

Growth hormones are among the vital hormones in the human body. The hormone allows for optimal body functions. Without the growth hormone, body systems slow down and fail to function as required. Notably, the production of growth hormones reduces with age. [3] The production is highest in children and plateaus at the age of 20. It then reduces throughout the subsequent ages. Obesity, chronic diseases, sedentary lifestyle, and high carbohydrates can make the decline in production of growth hormone worse. Also, growth hormone deficiency speeds up the aging process. Fortunately, human growth therapy has proven to help in increasing levels of growth hormones.

Purchasing HGH Supplements

Human growth hormone is vital in the overall bodily functions. You also need to know that the market is filled with supplements that are not genuine. Such products are a waste of your money, and they can lead to dangerous side effects. Therefore, it would help to be careful when purchasing HGH supplements. The best way to get the best results of HGH is to consult a doctor to make sure that you buy effective and safe supplements and injections.


HGH can stay in your body system for a few hours. But, factors like age and gender determine the length of time HGH remains in the body. Taking HGH reduction can lead to potentially disastrous consequences, especially if you don’t have a prescription from a physician. [1] Look out for signs of growth hormone deficiency and consult a doctor for the appropriate treatment.
