I use both actually. Used to be underweight, so I started my cycle with HGH, it did help me to bulk up. In 4 months, I went from 60lbs to 95lbs. Then I started a new cycle on steroids, just for a month. And then I went right back to HGH and started working out 3-5 times a week just to balance things up. I want to thank my vendor Chris for guiding me through out this journey. He wasn't obliged to do so, but he did. If you don't have a supplier yet, he's your guy, and he'll help push through.
