I am 28 i have been taking this on and off for 2 years. IT IS GREAT FOR WORKING OUT!!!! I recover faster, i feel stronger, i loose weight. this thing rocks im on my 4-5th bottle.. each bottle is HUGE, but so is the amount ur supposed to take.. Although when u work out ur muscle gain is so quick u tend to gain weight before u loose any!!
I get compliments on my facial complextion more than my sister! "your GLOWING!" "your skin is so nice" i get these comments all the time and im a GUY!!!!! i never put 2 and 2 together before though,,, and i realized its this product. i thought i was just pretty~! HAHA!.
Also i've had knee surgery, replaced my acl and torn miniscus. This is most definitely helpful for my knee. i always have a gnawing ... pain/tingling/ache whatever u may call it, those with serious knee issues know this well. This helps... i dont know how much more compared to glucosamine and msn... but those pills are big too.. so i tend to take this if i have to choose one.. but i take both regularly, daily, when im serious about working out, to better protect my knees and my joints.
It does have a smell associated with it, the longer u have the bottle the more the smell ;p, but once u put it in ur mouth and wash it down, smell all gone ;p
I HIGHLY RECOMMEND THIS for anybody working out, joint problems, want prettier skin.. young or old.. for the chance it may work for u
