Just started mine, first time hgh user 2ius to start. Good vacum in the vial, great packaging. Most of the bro's that are using this have had very good results, some great. I won't know for myself for at least a week or so, if I experiance any sides, better sleep, numbness. I know that sides are not the best indication of good hgh, but it will be months before I will see real results. Will be bumping to 4ius at the end of the month.
