depends on what you goals and pocketbook is like....gh for me isnt a cylce but a year long or should i say life long cycle....i did a cycle last year of gh only for about 3 months..i used genotropin but i wasnt training or eating right and i gained a lot of water...this time around is quite different...8 weeks in and i have made the best and quickest gains in the 20 years of jucing...
