Yeah I'm no good with powdered stuff...*screws up face at the thought* haha
umm, I'd say I've been taking them since maybe dec last year. However dec/jan I was really slack with them as I was away on holidays a lot and didn't want to lug them around with me. Jan/Feb I was really consistent with them and got about an inch growth. Of course I cannot say 100% that it was completely due to the MSM.
I have also found that my hip (I had a arthroscopy a few year back and have scaring in my articular cartilage) has been feeling a lot better - It usually gets sore when I stand to much of start something new, but it's been pretty good.
No complaints. Oh I should warn you, the GNC tablets are rather big. I personally, don't find them hard to take though.
