How to increases growth hormones at the age of 21 ?

Growth Hormone: It is not possible. You are at an age now where there will be no more growth. It would be best to be grateful for being alive and healthy.

Increased GH level: To increase growth hormone (g) you need to get rid of belly fat and do vigorous exercise. Staying active has also shown to optimize the level of hgh in a person’s body. Stay away from high-glycemic-load carbohydrates, as Insulin or “insulin spikes” have been shown to greatly inhibit hgh secretion. Sleeping well is another good way to increase your g level. Good luck.
