i believe that some cheaper generics have things in them that mimic sides like some kind of sleep aid and something to water bloat you. I've heard of cheaper generics put 10lbs of water on people within a week and pretty much knocking people out like they drank a bottle of nyquil on 2.5 iu/day, but they still experienced fat loss so I think it was likely legit just with something added... where as other better quality or at least more expensive generics give the fat loss, good sleep, but don't come with crazy sedative effects.... Personally I think sides are not a good indication of potency, you shouldn't be putting on crazy insane water, you shouldn't be knocked out all day, and your wrists shouldn't be aching at reasonably low doses of 4iu/day or less of generics... There is something else added to do these things IMO, but that isn't to say there is no real gh in them, just that they are attempting to make the meat heads get a clear signal that the stuff is real because for some reason many think that sides=potency which IMO is not the case with hgh...
even yates and the big pros would say things like "yea I ran it, didn't really see much while I was using it, but then I was able to break through plateaus of growth that I couldn't previously"... It's not something that should transform you in to a mass monster or that you should notice much of anything while on it besides a bit of fat loss, it's just growing new fibers that you previously didn't have before, it will take time for you to grow these new fibers. increasing your dosage until your wrists hurt might make you feel like it's working but IMO it's a sign that you're doing wayyyy too much and growing things you probably don't want growing long term. If I were to ever get a prescription and use HGH legally which is the only way I would condone usage....................... .... .. I would never exceed more than 1.5iu in a single administration, and I would not do this more than 2x a day regardless of my tendons aching or not.
