^^That's a lot of epi, typo? lol
"best dose" doesn't exist. If you want gains and don't get sides, or can tolerate them without caring, than a higher dose will usually be "better." It doesn't mean anything here.
This is how you should run Epi. Buy 2 bottles. Start at 2 a day, or 3 a day if you're a little heavier. After a week or two, bump up the dose, keep adjusting the dose based on how you feel. Most people say 40mg is the sweet spot. I would run the cycle out for more like 5 weeks.
