No Supplements required for you to achieve maximun GH Release. We all have this hormone in abundance, but with aging, it's release slow down. You can increase the release of this hormone, which will stimulate Muscle Growth, by simply following this suggestion.
Excercise on an EMPTY stomach. Do NOT eat at least 1 hour prior to exercise! Drink only water before, during, and after your workout. Then, nothing for at least 1 hour after your workout. Its as simple as that.
During the evening, when your body begins to repair itself, more GH will be released from doing to this type of stimulation.
Anyway, like all news/advice, take it or leave it.
