Arm Workout for a Hard musclegainer

[aet63]

Hello,

First of all sorry for my English.

I'm planning to do steroid cycle (3rd) and i've just finished designing of my cycle plan and workout-nutrition plan.

But i have questions about workout plan for my biceps and triceps muscles. I'm having problems on gaining mass on this muscles. Now, i think it will be good to increase volume for these muscles. I'm doing high-volume for my legs (total 18 sets without Calves workout) and had very good results. That's why, i think to increase volume.

I've planned to do this workout. Is this suitable for me as an hard muscle gainer for these muscle groups ?

Biceps (on Upper Back day)
5 sets of 5 reps (%80 of 1RM) Biceps Curl (Wide Grip)
3 sets of 8 reps Preacher Curl with Z-Bar
3 sets of 8 reps Hammer Curl
3 sets of 10 reps Zottman Curl

Forearm (on Upper Back after Biceps)
3 sets of 10 reps Reverse Curl
3 sets of 10 reps Wrist Curl

Triceps (on Chest day)
5 sets of 5 reps (%80 of 1RM) Close-Grip Bench Press
3 sets of 10 reps Push-down
3 sets of 10 reps Reverse Grip Push-down
3 sets of 12 reps Rope Push-down

Thanks a lot in advance.
