Well that really depends. Honestly when running the test/tren combo I usually opt to keep my tren high, and my test low. (this way I rely on the tren to do most of the work in cutting up my body..)
This is what I do:
Prop (weeks 1 - 12) @ 50mg ED
Tren-A (weeks 1 - 11) @ 100mg ED
IMO, you could start @ 75mg ED, and see how the sides treat you... and then you could bump the dosage up to 100mg ED if you feel you can handle the increase.
And BTW, the reason I keep on saying prop is because i'm not a huge fan of mixing long and short esters in the same cycle.
Also, your goal is to cut; 300mg of test-C is going to do little to nothing for you IMO since you're already on TRT. (IE) if your TRT dosage is 150-200mg EW, then doubling it will not make a huge impact at all. So yah... I would either up the tren... or just up the test... but honestly it's your call.. lol, just suggestions right
