First off, this is a great product to take that is non stimulant, and helps reduce your body fat. I loved taking it, pills are easy to take, saw a small reduction in appetite, I saw great results in body definition, and highly recommend, would be a great product to stack with a fat burner.

Definitely, one of the best products I have tried.

Good Product
I stacked this with MuscleTech's Hydroxycut Non-Stim 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. This product is also effective by itself as CLA has been proven scientifically to add in fat loss.

Another Great MuscleTech products
I haven’t bought CLA in a while since having a bad experience with a different brand. But decided to try this Muscletech product and it has helped with boosting fat loss. No side effects and no stim so works great stacking it with other stim fat burners to get the best of both worlds and increase the fat loss.

Didn't notice a difference compared to standard CLA

Great CLA
This is the best CLA I’ve tried. Really helped curb my appetite and shed a few extra pounds.
October 14, 2017
It works
This is a new line and I have found it to be pretty effective. I am always using stim products so when I started using this I was skeptical. I was able to actually shred 4lbs in a matter of a week or so by taking this consistently. No crash product which is great and it suppresses hunger which is great.

Multiple Forms of CLA
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 Hydroxycut Non-Stim. 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.

Will this work for women ?
A shopper on Apr 16, 2016
BEST ANSWER: Yes, CLA-4x BLACK ONYX works for women as well, especially when paired with Hydroxycut SX-7.
How long can you take this before stopping? It says 60 days but is that 60 days before your best results or don't take for more than 60 days in a row?
A shopper on May 25, 2016
Can you eat whatever you want?
A shopper on Apr 18, 2016
BEST ANSWER: I try to eat clean & lean throughout the week, with one "cheat day" on the weekend, while taking CLA-4x BLACK ONYX with Hydroxycut SX-7. The pounds almost melt away. I imagine that if you "eat whatever you want", the product may work, but you certainly wouldn't see the results as quickly.
Is this stuff more powerful than total lean 2000mg cla?
A shopper on May 28, 2016
Is this item available in stores?
A shopper on Apr 23, 2016
BEST ANSWER: Available in stores, or can be shipped. Purchased the Muscletech CLA-4x SX-7 Black Onyx in the local GNC today. Can't wait to try it!
I forgot to take it before I ate. Can I still take it after I ate?
