I am going to say that I believe this is a solid product. I have been doing 400mgs a day going into my third week. My gym time has actually not been how I have planned (Thanks to Life)but I see my size and thickness returning as well as see the definition coming in. I feel pretty good so I would have to say it is doing a pretty impressive job. I hope to get the gym time on track.I still have 4weeks to go on this run. Looking forward to all the gains.
