I am just the opposite. Nitro Tech makes my ass explode

I made 2 shakes out of the Nitro Tech container and both times within 20 minutes I barely made it to the shitter. That crap (no pun) went right back to GNC. And of course I even told them about the ass explosions (hehehehehe)

Used the first MetRx shake about 4 hours ago and the ass is still intact.
