Bought this for our German Shepherd. great quality for the price, best bargain and works well. Our dog used to whine a lot when she would get up (German shepherds are prone to hip problems) but after using this for 2-3 weeks she stopped whining and became more active.
I have arthritis in my neck, which makes it painful to turn my head. After taking the recommended daily high dose of 21st Century Glucosamine/Chondroitin for a week, my pain went away. I trust the quality of this product and continue to take it daily. The bottles came securely packaged, delivery fee was reasonable, and shipping took just over 2 weeks to Thailand.
I've been taking this strength for a long time and I'm now happy I can get it from iHerb (instead of hoping to find it in stores) because iHerb's delivery is so quick and they list the expiration date online so you know before you buy. Can't beat that!
