2 weeks into S4 andarine discussion

So I’m about a week and a half going on 2 weeks now of my 8 week 50mg dosage of S4 split in the am and in the PM, I haven’t experienced the vision side effect witch is cause for concern for me witch makes me think my source is bunk, only thing I’ve noticed so far is strength going up a little bit during the cut and slightly better pumps, haven’t experienced the vascular or “dry” effect people say S4 gives, it has been underwhelming to say the least because I thought S4 worked like a anavar or a “minny winny” is what my source told me it acts like, am I overreacting to quick or do I have to keep waiting it out?
