I've been searching for a replacement of Hydroxystim and this is it! The theanine keeps me calm and focused. I usually can't tolerate more than 100mg of caffeine but I can with this product due to the other ingredients. The focus is unreal. Plus it doesn't overheat or sweat too much like other products (Hydroxycut sx 7 red etc.) so I can workout 2+ hours without a crash later in the day.


I have been using this product for over 2 years now. Whenever I have to get shredded for shoots, this in combination with CLA's, good client diet and extra cardio gets the job done time and time again. I just ordered what should be my 10th bottle in 4 years. I also use this as a pre-workout since I train in the morning. For those nights when I only get 4 or 5 hours of sleep, I pop 2 of these and I am pumped in the Gym as I slept for over 10 hours. I have tried a few other products out there including the Hydroxycut Elite by Muscle-Tech but this is by far their best product!!!


good product for fat burner, on a good diet, with cardio it definitely helped me shed some fat. Also no jittery feelings, good appetite suppressant, good energy, and not to crazy high of a caffeine content per serving which was nice.


Always find Hydroxycut to be great at suppressing my appetite and this version does exactly that without feeling jittery Provides s good energy boost so I would use it pre morning cardio and was pleased with the results


Good clean energy, no jitters and good focus.


Love seeing muscletech constantly improving their tried and tested supplements!


This product was absolutely great! Gave me great energy and I lost a good amount of weight!


I've been using it early in the morning and late afternoon and there is no jitters, but my energy levels have really gone up. Helps me get through my workouts and has helped on losing a couple of lbs.


No jitters. Clarity. Focus. Smooth delivery. Sweat levels increased. A single pill is optimal.


Helped me lose weight gave me a good boost


This is the best product on the market and highly recommend everyone use it if you are looking to lose weight.


This stuff is killing the competition, I’ve already lost 10 pounds and all I e done is workout 3 days a week and eat a balanced diet. Gives me a ton of energy and mental clarity which makes my stressful days at work seem like nothing! Great way to jump start cutting season!


This is definitely the best hydroxycut they have out there! I got ripped QUICK. I can already see my abs coming in! Definitely recommend!


No jitters and amazing energy! I took this product in combination with SX-7 Black Onyx CLA and Ultra Carnitine and I have been seeing an increase in muscle definition. You get lasting energy with this product and great focus as well! I usually take one when I wake up and then later in the afternoon and it has done me wonders!
