Well I've been running s4 for around 1 month, within like the second week I started noticing insane vascularity! Like I literally walked into work after the gym and everyone was staring at me, had some proper dick skin going on. Anyways the sides aren't any where near as bad as people say they are, I started first 2 weeks 50mg, now I'm at 75mg how long should I wait until I bump up to 100mg? I only notice a slight yellow tint and very bad night vision, like I'm pretty much blind at night but it's all good, I can deal with the bad night vision.
