Great product. New increases in FTP!

I was hesitant at first but gave Extreme Endurance a try. I took it consistantly and started see a shift upwards in FTP in about 3 weeks. It has also helped greatly with recovery. I'm a believer and a happy customer!

5 Way Bypass open heart surgery

50 weeks ago, family genetics caught up to me. Fortunately I caught it before a heart attack or stroke. I had my first surgery of my life a 5 way bypass. I had been training for the last seven years, trail running, mountain biking, road cycling, CrossFit, strength training and SUP. I had tried Xendurance prior and was pleased with. Now 50 weeks post surgery this product is tremendously helping get back my endurance, stamina and strength!
