So i decided to add S-4 to my GW and SR that I'm currently running. After much debate in my mind, due to the vision thing I decide to say fuck it and try it out since I've also read great things about it when cutting. I started at 50mg for the past 4 days and last night's workout was so good I almost wanted to laugh. Muscles felt rock hard!. Not so much like a pump but just extremely concrete solid!. Strength was great even though im in a caloric deficit. I can't get over how solid i felt and the vascularity was insane. No sides yet (hopefully very minimal) I wont increase/decrease mgs for 2 weeks but so far im extremely surprised at the effect it has already. For those lucky enough to have ran this at 100mg, Must be awesome!
