A test e and deca cycle would be perfect then for the growth. And as long as your diet is on point, it's possible to build some lean tissue and lose some fat.
I would suggest that deca be ran for 12 weeks. It is a long ester and takes more than 8 weeks to really start working.
So I'd run test for 14 and deca for 12.
Have you thought about dosages? And a planned pct?
Another question, have you had blood work done yet?
