I have been spending a lot of time gathering information on hgh and I'm about to try and pick a supplier who has good purity and decent price. These are his claims, 99.9% purity and a serum test will come back 20ng. His 99% purity will show 16 ng on the blood test and the. There is the 98% and there is no claim. THIS IS MY QUESTION: does anyone have experience with hgh and this blood serum test? Does this sound accurate? Any info would be appreciated. I'm new to most of this and trying to minimize the change of getting ripped off or injecting some fucked up shit into my body!
