Great training aid
I've been using Endurance Excel for a while now. I run marathons and Ultras and I find I am able to train harder, and have gotten strong with the Endurance Excel. I also have noticed I am able to lose weight with it and able to maintain my weight. I can tell a difference when I am not taking them as oppose to when I am. I have highly recommended this product.

Endurox Excel Delivers!
Looking to gain an edge on my competitors in running and bring down my marathon time. Started taking Endurox and with in a few days notice my long run and track workouts where easier. Also lost 8 pounds in 2 weeks after taking. Went from a 3:41 marathon in the spring to a 3:14 in the fall. This product is the real deal. Now my running partner is taking it and the results are the same. His running times are going down. Been taking this product for 6 months.

Let me shed some light on Endurox
I want to shed some light on this product. I purchased it with some skepticism and really didn't know what I was getting. Before I get into that, just to give my background, I am a long distance runner and typically do two 10 mile training runs during the week and a 16-22 mile long run on the weekends and I usually maintain an average pace in the 6:50's.

I purchased Endurox thinking it was a pre-race type energy booster but that's not what it is at all. This is a herbal supplement that directs you to take it daily. So you will NOT feel anything after 1 or 2 doses. On training days I try to take it with a meal before any runs but I really don't think it makes a difference when you take it. After about 2 weeks of using the supplement I was pushing myself harder and running faster and had my average pace as low as 6:38. Key things I noticed was that I had a lot more left at the end of my runs where as historically I am usually pretty beat by the end of the run. I also noticed that I could increase my speed much faster and maintain it for longer (I had a 6:04 mile towards the end of a run which is one of my best times for a mile I've had). Look, I'm not going to sit here and say that I know for sure this product is responsible for my increase in time but this was my experience while I was taking the supplement.

Unfortunately I sustained a hip injury and had to stop running. I was very disappointed as I wanted to see how much faster I could get. Perhaps it would be wise to gradually increase your speeds over the course of time to reduce abnormal stress on the body. But I think there is a good chance this product gives you the energy and ability to push your body harder. I will definitely resume usage once I am running again.

I didn't notice any difference in recovery in fact I think I experienced more soreness simply because I was able to push my body harder than usual. I will continue taking Endurox once I am able to run again.

A shopper on Sep 23, 2012
BEST ANSWER: You should first be evaluated by a physician to make sure you do not have any underlying illness or disease process causing your symptoms. If you get a clean bill of health, this formula will help you build endurance, raises your lactate threshold, speed workout recovery and increase your cardiac efficiency by lowering heart rate while maintaining the same level of workout intensity.

I bought this product last night....i told the lady in the store that i am having trouble absorbing water...that i need more electrolytes. she suggested this product. I feel like it's different than the powders....can you help clarify?
A shopper on Aug 7, 2012
BEST ANSWER: This product is not made with water or electrolyte absorption in mind, it slows the build up of lactic acid reducing muscle fatigue, and also increases fat metabolism.
