When I do higher carbs on tren I end up sweating all over the place even though I haven't seen anything about 10% bf in years.
Lower carbs for me no matter what. That way if I'm feeling like a pig, I can just eat to my heart's content without a problem. One thing I can note is that after a big "carb up" (not really carb up, just me being a pig) the next morning I'm fucking sliced and diced and very full. Tren definitive helps with the composition but I don't care to nit pick things. It works, so I inject it. You don't need a lot either so I don't even see the need to break it down any further. A ml EOD and you're golden.
