DIET is key. tren kills my appetite.. I always want to eat a ton after my workouts, when i'm on tren i feel sick just looking at food after a workout.
best bet is drink a ton of water and force feed yourself .. yes tren does add mass and strength, but since food is so anabolic you won't get as much as you would like. thats why for pure bulking a npp/dbol/test cycle will give you the appetite of pregnant woman.
