Sorry to hear you crashed on the old version of Noxipro. I have heard that before on 1,3 products, certain ones make you crash while others do not have that effect. The Noxipro Chrome was the last version, while we still are selling it, we are not producing it any longer. Reason being is that it never really took off like we were planning. Part of it was our fault in not marketing it and the other issue was people wanted something similar to the original. The Noxipro Chrome is a great product for performance, but its easy to overdue it due to the caffeine and amount of alpha yohimbine in the formula, plus the taste was not great compared to the original. Part of the test issue was the amount of stuff in the formula was hard to flavor. The newest version will simply be called, "Noxipro" again and yes it is way more effective for energy and focus without making you feel sick due to less stims. We are using Amp, so that helps enhance any amount of caffeine similar to 1,3. I haven't had anybody crash on the new formula yet, but each person is different so I'm sure occasionally some one will. I used to crash a bit on the 1,3 version myself, but the new version I personally haven't had that issue at all. I take 1.5 scoops about 20 minutes before I leave the house to go train and it hits me pretty quick.
