Yeah I'm using it but I have had no side efx yet and I've been doing 6 IU's a day for the last 9 days. No carpel tunnel on the hands, swelling of hands, etc. I also took a very close look at one of the ampules with the powder and I could tell it had been peeled off then put back on for whatever reason, maybe b/c who ever had it put on saw that it was uneven. The reason I could tell is b/c below the label there was part of the sticky part with the paper still attached and where the label was moved up to it was missing that part of the sticky underside. Just my sharp eye caught it. I certainly hope that if it is counterfeit it is real though, but next time I'll be spending the extra couple hundred and try a holo kit to see if there is a difference.
