I picked this up a couple of years ago for $16 and for that price it was totally worth it, now it's priced at $25 and for that I personally wouldn't purchase it. I use this product and Glutamine Powder after hiking in the mountains and the next day my old body isn't sore and hurting like it used to be. The green apple flavor is nice and works well with whatever kind of gatorade I have on me to mix it with, not sure if I've ever mixed it with H20. It does what I expect from it, but if it helps the soreness of hiking I imagine it would probably help after a long workout with weight.
