Is the tren a for bulking or cutting?
i've seen it both ways and it really comes down to your diet. If you're running a caloric deficient diet you will lean up and vice versa for surplus.
Im on my first tren run as well. Doing 600mg tren ace a week, and 400mg test E. So far , very little sides, but its only been a little over a week.
600mg of ace for a newbie seems a lot... guess its ace so if sides are bad u can back it down..
He can't be a newbie forever, if he thinks is time to lose virginity, than be it
