I am doing research in the realms of shorter esters; Prop, Npp, Tren ace. I've read alot about pinning schedules and i can't seem to wrap my head around it. We have seven days in a week (Obviously) So would pinning every monday, wednesday, and friday be sufficient? Or would that extra day sunday make a difference? Would it be preferable to pin M, W, F, & sunday, than continue, or would pinning two days in a row mess anything up?
