You're talking about S4 with the night vision. Ostarine doesn't show any changes with vision.
I've thought about doing a test cycle before but mainly because my test(after lab testing) was on the low average but also to help in my weight loss goal I set for myself and about in the same boat as being scared as hell to try it. After the doc said it was a most likely a life time thing I figured my short term goals isn't worth the long term affects.
