"Dear Proline:

I purchased the Ultragen RS-Recovery cappuccino flavor by first endurance and do not like the way it mixes. The product works well but I will not purchase it next time due to the foam head that forms every time I mix it. If I use a blender bottle it is almost all foam. If I just use a spoon and mix it in a glass its better but still not acceptable. To much product lost in the foam you cant drink. Not wanting a refund, just passing on my experience.

Fastest Shipping - Best Customer Service

These guys have the fastest shipping and some of the best customer service I've ever experienced from an online store. Many endurance and recovery supplements - this one is the best I've used. You may be able to find it elsewhere for less at a sale price, but if you're like me I want my supplements when I need them, not 2 or 3 weeks later. Amazon.com has better prices, but don't buy there is you care to see your purchase within a reasonable amount of time. Optygen HP on Sale at ProLine Sports Nutrition - plus get awesome 1-2 day shipping Free of charges. No better online supplement store than right here!

Optygen HP vs. intelligent Endurance

Began taking Intelligent Endurance 1 month prior to Chicago Marathon. Ran the marathon in 3:15:34 which was beat my previous PR by 8 minutes. I really believe the supplement helped. The most noticeable impact of the supplement appeared to be oxygen utilization. It seemed that my breathing was easier on harder efforts. Only negative I experienced was a little bit of sour stomach. I usually took the supplement first thing in the morning and followed it up with the FRS low-cal Mango-Orange drink. On several occasions, I would experience some nausea that I had not experienced when only taking the FRS drink alone.

Amazing endurance product

Optygen HP helps with the leg cramps I get often after my workouts and took away the lethargic effects of skiing at high altitude this year. It did not decrease my max or resting heart rate, however, it enabled me to exercise at my max heart rate during training and races. Well worth a try if you haven't yet.
