Decide on a dose anywhere between 400-600mg Test for your first cycle and go with that. It doesn't have to be 2cc exactly, 2cc is going to vary based on what your gear is dosed at. 2CC of gear dosed at 250mg/ml = 500mg total.
The reason for dropping the Tren is because the only thing you should use and need is Test for a first cycle. You can make solid gains provided your diet is correct on just 400mg Test even, 600mg will be better though of course. Has Test+Tren been done for a first cycle? Ofcourse. Should you? No, stick with the test you will be pleased. Save the tren for a few cycles down the track
You should notice the test kick in quicker than usual considering it's got acetate, prop and phenylprop in it (short esters), you could probably split 600mg total into Mon, Wed, Fri shots because there is enough short ester to warrant that frequency IMO. Not needed though, that's just a choice you could make it you didn't mind it. You should notice by the end of week 2 stronger libido, sense of well-being/feeling of being on, nice fullness and pumps which get stronger as the weeks go on (by week 8 it should be in full force).
Enjoy
