since your arms so messed up...why not jump on gh at 5iu plus a day run it nonstop...run some deca to help repair the tendons and your hrt dose
do just all cardio,extreme light weight and high reps...spend the next year getting your body back together and strengthened then gradually work your way up...instead of trying to go for mass and strength..start with the inside out? get your base back in good condition then go form there
