Number one depending on the test its gonna be a large shot nothing over 2ml should be shot in one shot ..... i hope ur talkin bout test400.... but still 2.5ml in one shots quite a bit and i hear it hurts like hell and is underdosed (dont quote me on it! im not 100% sure just something ive read on another board)
but if it is test400 do 1.25 ml mon and 1.25ml thurs
I don't know what kind of test ur using but I'd say 2x/week over 1x/week no matter what it is. This keeps your blood levels stable. I do 2.5cc in my glute 2x/week with no problems. Sometime I do 1.25cc in each quad but then I can hardly walk for a couple of days.
don't mean to flame you, dude, but that's a HELL of a lot of test per week!!! how many cycles have you done before? what's your stats? what else are you stacking it with?
Ideally you should split it up as much as possible to ensure steady levels of testosterone. I'm running 1000mg of enanthate right now and shoot like this.
Mon: 1cc right bi
Tue: 1cc right quad
Thu: 1cc left bi
Fri: 1cc left quad
This keeps androgen levels pretty steady so there aren't a lot of fluctuations which can cause undesirable sides and inconsistant anabolic activity.
