From my reading TC tends to peak for most 2-3 days after injecting then start dropping as the cypionate ester is cleaved off. I peak 2 days or so after injection. So without blood work you could easily be over the top most of the week. Since you can be at 1100 the day after and may rise for 2 more days.Not sure, I've always done it day after per my Doc's instructions to be honest. I don't think it's going past the normal scale though.
