Hydroxycut non stimulant Black Onyx
I have been using this product for a few days now and I truly enjoy it. It definently helps with weight loss because it surpresses your appetite and helps you to not overeat and gain extra weight by doing so. I would highly recommend this product to people who have issues with over eating and need to lose some weight when exercising and dieting isn't enough.

Move on, these are useless
Nothing at all. With performix I least could feel the appetite suppressant working. I'm afraid this was a total waste of $

Pleasantly Surprised....
I was hesitant to try out a non-stim product but, it's seems as though the industry and overall fitness culture is shifting more and more towards this platform. That being said, having used many of this products predecessors, i,e first gen hydroxycut etc I was surprised to find that the results and more over the benefits of a product like this were exactly what I needed. What I liked most was the fact I could use this product in conjunction with my pre workout and not feel overloaded. I did receive this product as a test from MuscleTech and like any other similar product out there, it isn't going to do the heavy lifting for you, but I found that by maintaining a sold/lean diet while using SX-7 the results were right on par. I would highly recommend giving it a try.

Lost hard to lose weight
I am in my mid 40's and losing weight has become a chore. It seemed that no matter what I did I could not shed the 8lbs I was looking to get rid of until I tried this. I like that this is also a non stimulant so I can take it at night to stop my night time cravings. I stayed on relatively the same diet and workout over a period of 4 weeks and lost almost 7 lbs so far.

Decided to give this product a try, and I am glad that I did. Absolutely no jitters! Which is great since I am caffeine sensitive. This product was the perfect stim-free weight loss supplement I was looking for while dieiting down for the summer.
