I like it!
My consistent regimen consists of protein shakes, pre-workout, BCAA, fish oil and a multivitamin. I typically fatigue at 1.5 hours lifting heavy. Once I added Muscle X Boost I can easily finish 2 hours energetically and prolly keep going for another hour. (Gym daycare limit is 2 hours...I have kids)

I am an avid daily use fitness model. I pride myself on being as all natural as possible or while maintaining peak performance. After reading the ingredients and researching the same, I found no reason not to utilize this product daily. I have found through a couple weeks of using the product that my endurance level remains stable throughout my workouts and my body fat percentage has shown a decrease with all other factors remaining constant. I have seen no adverse affects from using this product and the cost is significantly less than competitor products.

There are claims of increase in sex drive associated with this product. I do feel that those are indeed true and fairly predictable. When I was working out on a regular basis I started using Boost and I did notice an increase in energy and recovery. I do not take this every day anymore. The timing of the dose affects my sleep if I’m not careful…. Not sure what aspect of it plays a role. But for me a mid day dose does not affect my nights sleep. Interestingly, I notice an increase in sex drive approximately 16 hours after a dose… plan ahead haha. I will continue to order this product and use on a regular basis.

I saw this product and wanted to try something different as I was not achieving the results I wanted with my workouts, as a male in my early 50's. I started taking this and have been more consistent with my workouts. It has only been three weeks but I have dropped 4-5 pounds, see some muscle definition, and have noticed lower blood pressure readings (I check every day). I think that this supplement is very good as part of an overall healthy lifestyle and am glad that I found it.

I have been an avid believer in supplements for years and have been let down 95% of the time. I can honestly say that this is by FAR my favorite. It gives me great energy, improves my mood, and improves “performance.” I took a break from supplements for a couple years but recently got back on them. All a man needs is Vitamin C, Fish Oil, and Muscle Boost!

Reviewed in the United States on March 15, 2019

This product was pretty good. For me I took 3 pills prior to working out. I also experimented a bit and took two pills in the morning and then took two pills before working out. I found taking 3 pills before a workout helps. This is probably one the better products out there. Definitely recommend but I will probably try other stuff just to see. I'm on my third bottle now.
