It works
Just finished my 40th day. I don't feel any different while taking it but I lost more weight in 40 days than I have in 6 months.

Hydroxycut SX-7 Black Onyx
While taking this weight loss pills, I didn't fell anything happening. So I taught is was a waste. I didn't check the scale till I was half way done with the bottle and I was shocked. I lost around 9lbs is a short period of time. I must say that I was really impressed with this product. No side effects. Thanks

A strong contender in the weight-loss supplement market
I received this product from the team at MuscleTech to try out in exchange for an honest review. At the time of this review, I have taken Hydroxycut for 9 days. In my opinion a product like this cannot be used by itself while expecting it to do all the work of eliminating unwanted weight from your body. Rather, it needs to be combined with ideally a reduced calorie diet (a few hundred calories below your caloric maintenance) and an exercise regimen, as stated on the label. I take this before lunch and dinner. I’m very consistent with tracking caloric intake on a daily basis, and currently I am eating at my maintenance, so in theory I should not be gaining or losing a significant amount of weight. After a little over a week of taking this, my weight has actually gone done by one pound, so with training and diet being unchanged, it does seem like the product is working. If I were eating a little more below maintenance, I think the effects would be greater, but at present time I am not interested in shedding a lot of weight since I am already relatively lean. Since there are no stimulants, there isn’t any concerns about jitters and the other ingredients are fully disclosed which is nice. 2 capsules a day would last a little over a month, which is also nice.

Great product
I like this product for several reasons. For one I can take it at night and not worry about not getting to sleep. Also the serving size is only one pill, compared to similar products that you have to take several. I would recommend this product to anyone who is a hydroxycut fan.

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.

Love that it is non-stim, so I am well-able to take my pre-workout just a few hours after. I have only used it for a week, yet I am seeing pleasant results with my physique (with my diet & training on point). :)

Solid Results so far!
Non-stim products are the new trend it seems, and after trying I can see why. This product is easy to take, gives you what you need and will help shed some pounds when used correctly. It might sound weird, but I can honestly feel it working just as good as other products, but without the jittery feeling of the caffeine. I am looking forward to using this more and more as spring and summer get here. The entire SX-7 Black Onyx line looks amazing and has all the research to back it up.

I never thought...
That I could find a non-stim weight loss supplement that could have such a positive sensory effect on mood and in turn focus. this feels like the real deal. combined with my diet and exercise it's delivered on all fronts.

Great New Product
Been using burners off and on for a number of years. I got this one from the folks at Muscle Tech to see how I liked it. I like this very very much! Now that I'm Mid 30's, i don't need or want any supplements that make me feel like i'm about to explode. I laugh at myself now as that was the feeling i used to want but anyway. This one gave me a nice boost during my training and daily activities without going overboard. For me I got good usage out of it by taking it a few minutes before I did my pure cardio workouts. For those who train martial arts, this was also a big help during striking training. Aside from the benefits one random thing i loved about this..the packaging. I felt almost like a pro fitness athlete looking at the black and gold bottle. They should package all their products like this. Definitely looks great in my supplement cabinet at home. I would definitely recommend this and plan to use this product again!

Increased strength and energy
Been taking 4 caps everyday for 2 weeks now. I've noticed that I have more energy waking up and when I'm working out. Weights have also gone up for me as well as sense of well being. Will continue to finish up to see more results.
