Great Product
I stacked this with MuscleTech's CLA 4X SX-7, Test 3X SX-7, Ultra Carnitine 3X SX-7, & Apple Cider+ SX-7 for the ultimate weight loss stack. I've been taking these products for 2.5 weeks & loss 2.5 lbs. I am in a calorie deficit, tracking my macros to control all variables. The first thing I notice when I started taking them was a loss in appetite. I took them as directed before breakfast & lunch & prior to that I would normally be really hungry but that went away after taking them. I also like that it's non-stim because I take a pre workout & don't have to worry about stim overload. I highly recommend...

Another Great Hydroxy
For a product that doesn’t have any stimulants, it works great. With dieting and a good workout regimen, I saw progress in weight loss. Must try stacking it with my other supplements during the day to see how they work. I haven’t yet because I didn’t want to overdo it. but noticed without the stimulants I’m not jittery all day which is a plus since I work in an office.

Awesome Hydroxycut product
This works great! Was using new Clear Muscle product at same time and it made me hungry! By using this along with it, really helped keep appetite under control. Added energy and fat burning results.

Non-stim for the win
Usually haven't been a fan of these in the past, but realized my mind could be changed after the weight loss that happened. Curbed appetite and the energy without the crash is well worth it. Loved using this and will go to it again.

Stimulant Free Weight Loss
I received this product from MuscleTech to try out. I stacked it with the Black Oynx Hydroxycut SX-7 Ultra Carnitine, Test 3X, Apple Cider Vinegar and the Black Onyx SX-7 CLA. I like that none of the products contain stimulants and they help curb appetite. The pills are large but easy coated and to swallow. Each serving provides an adequate amount of weight-loss products coupled with additional enhancing elements.

I like using this in place of the standard hydroxycut for the times I don't want or need an energy boost. Solid product!

Give it a try!
Although no stimulant, this stuff sure delivers! Gives good energy while helping aid fat loss!

Good Non-stim
This worked great to help with snacking late at night. Love the fact they're non-stim. Still can get a great nights sleep when I take them later in the day.

Stim Free!!!
Love that MuscleTech finally made a Hydroxycut that allows me to continue using my pre-workout. I've tried several other Hydroxycuts and this one does just as good, if not better! Really stoked on there being a stim-free option though.

No jitters, Good sleep, Weight melts off!
Still shedding pounds like a beast, I really like this hydroxycut because I donâ??t get jittery like the ones with stimulants. Feel great, helps my appetite stay suppressed and this works as good as the other hydroxycut with stimulants but now I can fall asleep with no issue!
