Not really sure what you're asking, but I'm going to guess that you might be over thinking things. I personally do every other day most often, and sometimes every day. Last time I ran fast acting compounds I did every day for the fast stuff, so I was injecting YK-11, and Tren Ace every day, and every other day I'd throw whatever test I was using, along with primo into the syringe as well. Doing MWF (3x/week) vs EOD (3.5x/week) isn't going to make any noticeable difference. Esters like ace, prop, phenylprop, etc... Should be dosed every other day at a minimum in my opinion, but even with those, going MWF isn't going to make too much difference. Whatever you decide, just be consistent with it, and don't start skipping doses. Look at it the same way you do eating, training, and sleeping.
