I have definitely experienced the sides with it. The night vision was extremely scary because I was not ready for it. I was driving one night and had to get out of my car it was pitch dark outside. My vision was caput. Lesson learned. It was a great product other than that.
Wouldn't Andarine be a good one to accompany? I've seen several Carderine/Ostarine stacks too. Mr. Gemelli has quite a few informative videos on S4 (Andarine) which i think you would benefit.
