Aug 15, 2012 When you say built up a tolerance to it do you mean fat loss slowed? Or just a tolerance to the sides. If your fat loss slowed then you just needed to cut the cals a bit. But really I've never heard of fat loss slowing on DNP. I like the frozen drink idea. But ideally I would never run DNP in the summer. You're a nut! But you've done it safely so far so more power to ya bro.
