How can I measure my HGH levels?
HGH is in the body for a very short time. However, IGF-1 (insulin growth factor) is always in the body. According to recent research, this is the most effective way to measure growth hormone levels. To find out your IGF-1 level, you must have a blood and saliva test. The lower your IGF-1 level, the more effective growth hormone treatment will be.
