Axe & Sledge Ignition Switch Pre-Workout is quite possibly the most versatile pre-workout on the market. This pre-workout is designed for everyone and meant for everyone to be able to use. What's really unique about Ignition Switch is there's actually two different instructions and two different ingredient profiles. There's the "some stim" way to take it, and the "extreme stim" way to take it. For those of you who just want a kick in the butt to get to the gym and power through a workout, take the "some stim" way. For those of you who are "stim junkies" and want a lot of stim, take two scoops. What you can expect from Axe & Sledge Ignition Switch, is you can expect it to kick in about 15-20 minutes after taking it. You'll start to feel the energy rush through your body, you'll start to heat up and sweat a bit, and you'll start to feel that laser focus kick in. By the second or third rep you're going to be uber focused, and you'll begin to feel that mind and body effect you hear people talk about.
