Primoteston-Depot «Schering AG»

I got prescrivded Primoteston-Depot «Schering AG» 100 mg e.w
, efexor & remeron from my doctor, because i have pannic attacks and depresion, and have told him about my low libido and sex drive. I got shocked when he told about my terapi. I have been open about my earliyer cycles,drugs. I know that if I will gain mass, my cycle would look difrent, and is ment to cure my depression & anxtity.
I`s it posibole to gain some mas on this cycle, I will be on for at least one year. My normal test is 12 mg day.How should my diet look like when I am on so low doses.
