Test and a proper pct would be a good start! As said by Kornfed

You lost all your gains bc you didnt do a PCT. Your HPTA is still shut down which is causing you the erection problem.
Cut your cardio in half as well. Your going overboard and will lose muscle!

I would consider running a pct
pct 30 days long
clomid 50mg ed
nolva 20mgs ed

You should train each muscle as heavy as possible. 5-10 reps heavy!

Whats your diet look like? I cant help you with diet until I know what your currently eating. You gotta eat big to get big. A high protein diet & moderate carbs will get the job done & help you pack on some muscle.

What are your stats? Are you running a cycle now or plan to eventually.
For your erection problem I'd get some viagara or cialis until you restore your natural test levels..Its a quick fix..

If you have anymore questions post up! KF

If your in a hurry I'd consider running a test only cycle 500-750mgs a week.
That will help with your erection problem & pack on some mass!
