The system of measures for HGH is IU (international units) and mg (milligrams). 1 IU is equal to about 0.33 mg and 1 mg is equal to about 3IU.
The aim of your HGH therapy influences your dose. Usually the patients take 2IU a day for anti-aging goals, 4-6 IU for fitness, weight loss and bodybuilding purposes, 8-16 IU for the treatment of serious burns and recovery after injuries but for a short period of time.
The dosage of below 3IU a day causes no side effects but influences positively the skin, gives more energy and the possibility to eat junk food without weight gaining, improves your sleep, etc.
It is possible to notice some side effects after using of somatropin for a couple of weeks with the dosage of 4IU and higher. You may suffer from little water retention in your face, toes and fingers, as the growth hormone forces the muscle cells to hold more water and are inflated this way temporarily. Tingling sensation in palms and fingers are also possible. This side effect is known as carpal tunnel syndrome. Generally, this is the main side effect that the users can suffer from. The majority of athletes just ignore this side effect and proceed the HGH therapy as long as they need. If the syndrome bothers them too much, they reduce the dose or make a pause in the cycle until the syndrome disappears. Usually it is necessary to wait for 2-3 weeks to get rid of the carpal tunnel syndrome completely.
If you take 4IU or more a day, it is advisable to divide the dosage into 2 injections – one in the morning and the second in the late afternoon. Do not take HGH before going to bed, as your body produces endogenous HGH when you go to sleep and this is the third dose. The dose of HGH before going to bed can interfere with your own endogenous HGH production.
