Want HGH? Get a good endocrinologist to be your friend. Get a script from him, and let your insurance pay for it. Retail prices without insurance is about $1500 for about a 1-2 month supply depending on the brand you get (I suggest Lilly's Humatrope, it is the most expensive, but the best you can get no matter the cost). Black market prices for the most common like Serostim by Serono or Genotropin is about $450 per 126iu kit which is about a 2 month supply. To see the full benefits of it, stay on for at least 6 months. It takes quite a while to work, but once it starts, it's nothing short of dramatic loss of fat, and if you life, a huge imcrease in lean body mass. Strength gains are very small. Side effects with low to normal doses are almost non existant, except for maybe a bit of a wierd feeling of a bit of numbness in your hands. If you abuse it and take large doses, expect nasty side effects.
Oh, and IGF2 and it's variants do help increase normal somatropin production a little and actually helps you utilize any extra you may be injecting. By the way also, it's a very very small insulin needle that's used because it is a water-based drug, not thick oil based "hard" stuff.
