I've used this for about 18 months, and noticed some changes within 2-3 weeks I liked. After 2 months, it was really working, I felt. But the last 3 bottles I ordered have been different. I'm not sure if they changed it or I never noticed, but once it hits the air, you've got about an hour before it starts to dissolve. Not kidding. I've had times where I walked away for 2-3 hours and come back to powder. I've lost probably 50 of these from them falling apart. Looking for a substitute from now on.
I'm 53 years old and ordered this in hopes of improving energy, getting better sleep and lessening pain when lifting heavy weights.
What it didn't do:
-give me more energy
-improve my sleep
What it did do:
-significantly less soreness after work-outs
-less pain when lifting heavy weights, but not quite what I hoped for
I will be trying other brands.
