JINTROPIN ® –  a brand name for synthetic human growth hormone – somatropin. It is legally produced by the licensed factory in China, Gensci .

Despite the fact that HGH (Somatropin) creators initially synthesized it to treat GH-deficient children, it is highly popular in sports, especially in bodybuildingfor the following reasons:

      • Growth of muscle mass, caused by the acceleration of protein synthesis.
      • Loss of fat simultaneously with gaining muscles.
      • Improvement in cartilage quality.
      • Mild side effects.

It’s possible to say that HGH has divided bodybuilding into “before” and “after.” The tremendous rise in mass, which has started in the 1980s with Dorian Yates and then was kept by Ronnie Coleman, is caused mostly by HGH. Growth hormone helped them become leaner and not to lose muscle mass during cutting. Also, HGH enabled hyperplasia, which moved the limits of maximum muscle hypertrophy.

After the injection of growth hormone, it enters the bloodstream and then spreads around the body, concentrating in the liver, where it converts into IGF-1 (insulin-like growth factor). This substance is responsible for muscle growth, which is the main effect of HGH for bodybuilding. IGF-1 binds to its receptors in skeletal muscle tissue, thus accelerating protein synthesis.

The fat burning function of HGH is performed by growth hormone itself. The hormone binds to somatropin receptors, which leads to elevation of the level of free fatty acids (FFA). So, the body starts using fat, instead of carbohydrates, as an energy source.

Fat loss neither interacts with muscle growth nor interferes it. It is a unique feature of HGH, which allows you to gain lean muscles and lose fat altogether.

Another unique feature of growth hormone is hyperplasia, the increase in the number of muscle cells due to their proliferation. This effect is significant because HGH-induced muscle gains are permanent, and divided cells allow you to exceed your genetic limit for muscle mass.

Note: In order to make sure whether the Human Growth Hormone, or Jintropin is real or fake, Gensci has developed an anti-counterfeiting system. Enter the serial number (you can fiind it on the package) that contains 12 digits on the web site (


Jintropin/HGH should be administered a minimum of .5 I.U’ s and a maximum of 2IU’s daily 6 days a week with one day off. HGH should be given in the evening before bed. You should not eat anything an hour and half before and an hour and half after injection. Also do not eat foods high with glucose (sugar) three hours before taking HGH. The sugar with interfere with your bodies absorption of the HGH.

      1. Wash your hands before you begin.
      2. Mix (reconstitute) one vial of Jintropin with the amount of sterile diluent desired.
      3. After mixing, gently swirl the mixture in the vial until the powder is dissolved. Do not shake. The liquid should be clear with no white powder remaining.
      4. Withdraw the prescribed amount of Jintropin using the sterile needle and syringe.
      5. Choose a delivery site and clean it with an alcohol wipe. The best sites are those with a layer of fat between the skin and muscle, like the thigh, the back of the upper arm, the abdomen and the rear end. Use a different site every time, and do not deliver Jintropin to an area of the body where the skin is irritated, reddened, or bruised.
      6. Deliver Jintropin by pinching small area of skin and inserting needle into body at a 90 degree angle. Once needle is inserted into the body, depress needle plunger until HGH has been injected into the body.
      7. Apply pressure to the site using a gauze pad or cotton ball.
      8. Dispose of needles properly in a biohazardous waste container. Do not reuse needles or syringes.


Jintropin should be kept cool. This is essential once the product has been reconstituted (i.e. once the liquid and powder have been mixed). When reconstituted, the product must be kept in a fridge at near 5 degrees Celsius. However, Jintropin must not be frozen, and it is recommended to be used within 14 days after reconstitution.

But if the product is left unconstituted, then the shelf life is up to the expiry date marked on its box (normally more than 12 months). In this form, the product is more stable and less prone to heat damage. Jintropin recommends keeping the product cool, and it is advisable to still be stored in the fridge.

Jintropin can be “damaged” if it is exposed to excess temperatures. Undiluted, freeze-dried HGH powder in sterile vials may be safely stored at a temperature not exceeding 86 degrees Fahrenheit for up to 18 months. It may be safe up to 110 degrees Fahrenheit for a day or two before mixing and tolerated without a problem. Once water/diluent is added however, the liquid HGH must be kept refrigerated and used within 4 weeks, or the potency will slowly decline (in case your fridge is not so accurate, we recommend use within 14 days).

The reason GH is kept in a fridge after it has been mixed is NOT that it rots or spoils, but that after you have mixed it, there might be bacteria in the vial, and growth hormone is a protein, and they eat it! The result is that it would lose potency. So you want to keep it cold to keep bacteria from multiplying too fast, because there would eventually be a loss of potency.



Jintropin is a very safe supplement to use as long as the appropriate dosage is adhered to. However, abusing the compound has been shown to result in some very undesirable effects, such as abnormal swellings in the arms, legs, and joints. The swellings are incredibly painful, as well.

Moreover, using Jintropin at high doses has also been associated with gynecomastia. Gynecomastia refers to the condition characterized by the swelling or enlargement of breast tissue in men. This is a direct result of having unbalanced hormonal levels in the body.

The unmonitored use of this supplement can also predispose the individual to diabetes in addition to a variety of heart diseases when they grow older.

As such, even though Jintropin is considered safe, misusing the compound can result in a host of undesirable effects. In addition to misuse, age also seems to play a role in the manifestation of undesirable side effects.

For example, young men in their 20s and even 30s tend to have high levels of growth hormone in their bodies, especially if they live active lifestyles. As such, even a small dose of an HGH supplement such as Jintropin is likely to cause a hormonal imbalance within their bodies, thus resulting in adverse effects

This is why HGH supplements are mostly recommended for people past their 40s since they have very low levels of natural HGH inside their bodies. As such, supplementing with synthetic HGH can help bring their strength and performance back to where it was while they were in their 20s. Nonetheless, these individuals will also experience adverse effects if they misuse the supplement.

The other factor to be considered before using this supplement is the health of the user. Generally, people of good health should use this product in smaller quantities than those who are not of good health. Additionally, a person’s medical history can also play a role in the kind of effects they get. Certain medical conditions, as well as medications, can result in adverse effects when used together with this compound.

The bottom line, therefore, is that before you embark on using Jintropin or any other exogenous human growth hormone supplement, ensure that you first consult with a licensed doctor. They will evaluate you and advise you on whether you are the right candidate for the supplement. Moreover, they’ll monitor your journey with the compound to ensure that they curb any adverse side effects before they take a toll on you.
