I agree 110% with 52. Blue tops no matter what label is slapped on them (somatropin, kefei, etc, etc) have all worked WONDERFUL for me. I was just jolted from my afternoon nap because of my damn numb hands and sore wrists. I actually feel more sides, lethargy and see the same results (deep sleep, better skin quality within a few months, less b/f even while deep in a bulk, etc) than I did with the more expensive stuff. Sometimes you have to break down and spend the cash, but with this, the blues have been very good to me.
