It all depends on how much test you normally use, You are already taking about 400mg EW, so split the sust up into EOD shots, adding in what you need to reach the total MG's of test you normally use per wk. If you are newer to gear, you don't need it. You'll already be running about 1g of total hormone. If this is the case, save the sust for your next cycle, when you go back to an off season diet.
