ive been on their hgh for a while now, dont see much results, and ive ran blues and jintropin in the past. i was up to 10ius of serotropin ed and didnt notice any side effects. i thought i did at first but when i ran a kit of jins right after serotropin, i started to feel sides and better mood, then after the kit was finished, i went back to serotropin since i had 3 kits left, and the mood was gone, no numb fingers or better sleep, etc.
