awesome stuff!
my knees had been giving me some issues, since my childhood injury.  just walking up and down the stairs was becoming pretty painful.  I usually just used like a knee salve or icy hot, but I heard collagen was good for joints.  also does wonders for your skin!  so I am almost out of my bottle, because I really do feel a difference up and down stairs, plus my wrinkles aren't as noticeable!
