How much does HOT-ROX play into the whole Velocity Diet? I have taken HOT-ROX and a few other thermogenics (when ephedrine was still ok) and I think I’m immune to them somehow. I’ve never felt any of the warmth, energy, buzz, whatever. I think it’s mostly my body’s indifference to caffeine. I can drink a caffeinated soda right before bed and have no trouble sleeping. I hadn’t thought of checking my heart rate until today. So if I wanted to check HOT-ROX influenced vs Non HOT-ROX influenced what would be the best way to go about it? I’m been taking 2 to 4 tabs a day for the past couple weeks. I’d really like to try the V-Diet but if HOT-ROX is truly not doing much for me I need to know how much of a dent that would make in the expectations.
