If your seeing good weight gains why increase the doseage? 15lbs is a great gain so far. You holding much water or does it appear to be quality mass gained from the tren? It sounds to me your having a very succesful cycle. If your still motivated mentaly for the gym etc just keep it going. Although its nice i wouldnt worry if your not getting the extra gym mental motivation/feeling. Your seeing gains so why adjust? Your sex drive and everything else is all good. Let your body grow on the lowest dose possible. Dont fix something that isnt broken

Im seeing good gains on test e 250 and tren e 200 at week 4, it makes me think shall i up the dose? But its just being greedy

Keep up the good work!
