look man honestly , i wouldnt lower it , how many weeks are you in ? if it is your first few weeks , u can count on it that 10lb (if u put on that much ) is just water weigth which u will lose. also , u will not continue gaining if your diet remains the same , in order to keep on growing , you need to keep on eating more and more , the bigger u get , the more u will have to eat to miantain it or get even bigger . so if your diet remains the same , the gains will level out.u can lose weight on test if u are in a caloric deficit . all you realy have to do is watch your calories , u can take an Aromatase inhibitor (AI) to control water retention , but i wouldnt lower the dose to 300mg nor 400mg . 400 wouldnt make much a difference , and lower then that , id say theres not even a point of running test , u may as well have just stayed natural and porbably get the same results . either run the cycle properly , or dont run it at all if u arent ready for it , ill bet all the gains are water so far , expect that if u arent at least in week 5-6 , which im pretty sure u arent
