I have done some reading around and there seems to be a difference in opinion about cycling your hgh.
I read that it safer to cycle it 2 days off per week. This gives the pituitary gland a chance to notice that you are not providing your body with hgh naturally and continues to function normally.
My doctor says that you can do it every day and advises that it be used daily for maximum benefits.
Also, I read once that it does not effect the natural production of the pituitary gland because we are producing it most in the evening when we sleep and only supplementing the body during the day. Thus stimulation occurs in the evening and it is fine to do daily.
