Let’s define what hormone is. Hormone is a substance, body’s chemical messenger, produced by certain tissues (glands), and conveyed by the bloodstream to the intended destination to effect physiological activity, such as growth, sexual function, reproduction, mood and metabolism. The destination cell has a specific receptor that can only be activated by a specific type of a hormone. Hormones work slowly, over long time frames, and affect many different processes.

There are two main types of hormones: steroids and peptides. Steroids are known to be sex hormones related to fertility and virility. Steroid hormones are made from cholesterol and determine physical development from puberty on to old age. If a person does not synthesize the correct amount of steroids, Human Growth Hormones supplements can help.

Peptides are another form of hormones that regulate other functions such as sleep and sugar level in blood. Human growth hormone is an example of this sort of hormones that helps us burn fat, build up muscles, improve mood, emotions and sleep better. Another sort of peptide hormones – insulin regulates the process of converting sugar into cellular energy.

It takes only a tiny amount of changes in hormonal system to cause big changes in whole body. For example, studies have found that human growth hormone treatment improves physical appearance and increases resistance to some injuries.
