only the first month
by lynda

my husband and I took this product, and the first month went really well. We both had more energy we were able to push ourselves harder during workouts, but did notice some fatigue towards the end of the day.After the first month though our experiance was completely different...we notice a short boost in energy at the begining of the day but was short lived, then for the rest noting but total fatigue.Sorry but we wont be using this at all anymore, nore do I suggest any one else.

Energy Enhancer
by Stephen Dordan

I am 40 and working out has gotten a lot harder. I started using Energy Enhancer as just a desperate move to have better workouts. This product lets me get my fullest out of a work out and I spend twice the time I did before working out hard. Very positive results here.

For those sleepless nights.
by Bridget Roberts

As a mother of two young children, I find it hard keeping my eyes open all day long. My day begins at 4 am and doesn't end until 1 a.m. the next morning. I have tried, a few energy drinks and pills, but nothing seemed to do the trick. Shortly after trying Pro Performance I seemed to have a burst of energy that wouldn't stop. As an added bonus I did not have trouble that night falling asleep when I needed to.

GNC product
by Mike Huang

This GNC product helps me keep all my mental focus and support the functions of my brain. During my intense sport training events, I need to use this energy supplement to keep up with what I'm doing. Pro Performance really does work and only takes about 30 minutes to show the effect.

Fancy names, Good Product
by Gordy

Pro Performance was one of three different energy enhancing products I used when trying to find the right one for me. The manufacturer, GNC, and the fancy lingo - Mental Focus and Thermo Burst - really grabbed my attention, so I purchased it. It consists of many of the usual ingredients in an energy booster, but does boast that it contains "No Artificial Colors, No Preservatives, Sodium Free, No Wheat, No Gluten, No Dairy, Yeast Free" for those with health issues related to any of that.

The Pro Performance Energy Enhancer comes in tablet form with a supply of 30 days. You take three Thermo Burst tablets daily (one hour before exercising) and do your workout routine as normal. It claims that it has a special formula to give you long lasting energy, but I found that it didn't outperform other products in that regard. I did however feel like I had extra energy and didn't become suddenly fatigued towards the end of the day.

The Mental Focus supplement requires 2 tablets daily (and they strongly emphasize that you do not exceed recommended intake). It is supposed to help your mental acruity and focus - but this a gray area in regards to actually noticing the results. Personally, I didn't notice any huge improvement, partially because I wouldn't even know what to look for! I feel as if this portion of Pro Performance is more of an attention grabbing gimmick, than actual helpful supplement.

I felt that it did the basics of what you would expect out of an energy enhancer, but is very expensive at around $40 for a 30 day supply. If you are a die hard GNC fan, than definitely give it a go since you know you will be getting a high quality product. Otherwise, check out some more affordable products without any big gimmicks.

I would recommend taking a look at Ultra Fuel Powder by TwinLab at ~$15 a supply. More of an energy and endurance supplement, it focuses on giving you a complete boost for your workout - compare and contrast with Pro Enhancer to see which better fits your needs
