A pill is often the easiest way for people to take any sort of health supplement. It is something that people are willing to try and are not afraid of. It is something that is known and something that most people do every day - whether they take a vitamin a day or they supplement with hgh in pill form.
Because of this desire for all health supplements to come in pill form, it is obvious that the industry has created hgh in this form. Not only is it readily accepted by the population, but it is cheap and easy to produce. HGH in pill form avoids the injection or spray forms that a lot of people cannot tolerate.
HGH in pill form can also be quite effective. It is at least as effective as that of the spray forms. One item of difference is that the pill form may have to be discontinued after a significant period of use. It is possible, and studies have come out that may support this, that hgh in pill form can have adverse effects on the pituitary gland forcing one to discontinue use for some time. Take a look at the comparison of different forms of hgh here.
