I noticed pretty much nothing from supplementing with glucosamine by itself. Joint supplements work best when taken in conjunction with one and another.
Look into the product n2joint rx from n2bm.com. It is a multi-ingredient joint formula. It makes dosing very simple. Take your 5 capsules per day and you're done.
Stack it with ostarine at 25mg/day and 3-6g of a high quality fish oil per day. Fish oil is a strong natural anti-inflammatory and will help lubricate your joints.
