From personal experience of using pharma HGH, HGH in average doses is not a game changer, its more like a booster when it comes to burning fat, also builds muscle but not nearly as strong as steroids. Its also dose dependent, when you start to use 10IU per day, it may start becoming a game changer. Whereas slin is a game changer, but for novice users, it changes game like, turning most users from bodybuilder to fat bodybuilder. During usage of slin, loading simple carbs should be avoided or it will retain fat. There is a video of Dave Palumbo about it, definitely recommended to watch. Name is: The TRUTH About "Growth".
