I have major sleeping problems mainly caused by stress and other factors. When I workout in the pm hours, it totally screws up my sleep for the night, but somehow since I've been using GW From Sarmsx, it actually helps me sleep better after my workouts, don't know how or why but it actually helps me. I must also to mention that GW is freaking amazing, I absolutely love this stuff. It works wonders, energy, fat loss, enhanced Cardio output. The first time I used it, I didn't want to leave the gym. Finally after 3 hours sweating down to my shoes, and only reason I stopped was because people working there were looking at me funny, like are you ever gonna leave or what? lol so I left!
