that is common, test E can take 4 weeks to really take effect and so sometimes people will take a double dose on the first shot. if you are doing only test then that is not a bad idea since the test e takes so long to hit your system. another way to do it is, say you are doing a cycle of 750mg a week, then take 3-4 shots of 750mg in your first week, don't worry about over doing it since the test e hits so slowly and its spread out. i hope you have HCG and don't forget to wait 4-5 weeks after your last shot to start PCT.
