I have noticed zero impact from taking this as directed. Seriously, has made no difference in recovery that I can tell. But maybe it's just me. Won't order again.

great product for the price!!!!!
This is a good value , it doesn't mix well but I find if I mix it with a little OJ or juice 4 to 6 oz its fine, might be a little gritty but it works very well for muscle fatigue. Aids in muscle recovery, however a good multi vitamin like Mega men will have enough Glutimine for your basic workout recovery
plus lets face it,it can get expensive and the average person is not sponsored.

Immune System
It's a great product that greatly helps your immune system. I'd suggest mixing with juice as it doesn't mix too well with water.

I would buy this product again.
I take it after my workouts with whey protein. I have noticed that my recovery time has quickened. I feel good the next day.

Great Stuff!!!
This stuff is great...helps so much with the soreness. After any kind of prolonged activity this will make it seem like it never happened. Been using since I found out about it....9 years I think.

Nice nutrition
I used everyday for boosting my muscle
great performance!
I bought this product for my father. He is a cancer patient and his doctor told him to use this product to build his body and might be able to reduce some side effects from the chemo/radiation therapy. He has used this product for one month and the result is good. He started to gain some weight and does not feel most of the side effects from the therapy.
