Hey brother, so with Sust, it has a lot of short esters. If you are only doing a small amount, you could split it up into 2 shots a week. But if you are doing 2cc or more, I would split it into EOD shots. And then if you are taking anything else, even long esters, I would split that into EOD too, just to keep the shots the same. That way its easy and the same each time. Let me know if you have any questions!!
