D4TS is not a weak go around that is for sure. When you purchase this product you are getting a very powerful fat burner. There is a reason why cellucor tells you to start slow and add it in when using. it contains around 150mg caffeine per cap which is on par wit many pre-workout powders out there, but also realize that it does contain yohimbine which many may have an adverse side effect to, so again be cautious when dosing this. It may make you sweat like crazy but also give you some crazy fat loss attributes. This is hands down one of the most powerful fat burners out there. I would suggest dosing 1 cap upon waking and then 1 cap later in the day (once you get used to the first cap) and slowly increase to a 2/1 dose if you can handle 450mg caffeine per day!
