I have herd about HGH and that it can make you feel younger and restore your energy, but have also herd bad about it like once you start you can't stop or all energy will be gone because the body now "depends" on the HGH...is there an alternate or something that can help increase energy/your metabolism and that you won't get "hooked on"...as I get older just need a little more...I miss my old metabolism

....I have friends that go to MD's and get legal "speed", two have lost weight and have more energy, feel 10 years younger, etc., but I don't want to go that route.
