Hi Iam using Amway products for the past three years My introduction to it is through my father, he was suffering from knee pain for over 2 years, When we consulted a doctor , he gave pain killer tablets, Im not interested in giving pain killer due to its side effects My friend told me about Amway products, my father took them for only 3 months - he fely very effective - one more advantage is no side effects If u want to know more about Amway products- pls tell me- Iam an Amway distributor- I can help u in all means Regards Ranjani
