Welcome to the forum.

To be brutally honest you're unsure how much to eat because you're not experienced enough to use tren.

At 22 years old you shouldn't be using any anabolics.

IMO you should stop now and PCT before you screw yourself up for the rest of your life.

If you decide to continue then follow Frank's advice on diet.

If your tren is legit then you won't put on any fat.
