Since the production of this hormone is naturally controlled by the body, it can help boost overall levels of testosterone in males. Testosterone is a male hormone that helps to determine many aspects of one's personality and physical masculine appearance. When a man's levels of testosterone drop, he may not have the sexual drive or muscle mass he once did. Using this kind of therapy to improve a man's testosterone levels can often times improve his overall outlook on life and his sexual function. A man's testosterone levels can also be boosted by using human growth hormone therapy. Studies have shown that human growth hormone therapy can help to increase a man's bone density. This may be due to the fact that this hormone helps to stimulate growth in the body, resulting in better bone health.

Peptides are proteins created from amino acids that help the body to function by improving cell signaling and stimulating healthy pituitary gland activity. They can also help to release additional human growth hormones naturally. This helps to reduce effects of ageing. Peptides can assist with building muscle, increasing energy and aid in workout and recovery. To determine if human growth hormone therapy is working, blood has to be analyzed throughout treatment to evaluate success. Taking note of physical appearance, like changes in weight, muscle tone and skin can also be of help to the therapist. To notice full benefits and have the body adjust to therapy can take 3-6 months.
