Glucosamine Plus

I have confidence in Douglas Laboratories. I have used a number of their products. I am pleased that in taking this glucosamine product my knee arthritis has not progressed. At 88 I am still quite active and hope to remain so. I can’t
expect a reversal in my condition so I am content.

The order was processed quickly and I received my order very fast . I like the product . I take the pills to help put cartridge in my disc . I have traction then my disc are scraped to stimulate blood then doc pulls apart for cartridge go in . I am 1 1/2 years with this . I was on the floor screaming before my treatment . Start with boiling chicken ( remove skin first ) remove chicken . Put bones and grizzle back in pot . Low boil 14 hours . Remove bones . Then drink .
