Mobility Powder - 4.5oz

i was given a free sample of the mobility powder by a nice sales lady. i have had knee pain and back troubles for years. i am 78 yrs old and i hurt alot. this product lives up to its name. on day 5 or 6 i could tell a difference and i have been using for 2 weeks now and things are going alot better. getting better everyday and i sleep better also which is a huge plus. i bought 3 so i dont run out.
