The weight gain you are looking for is not out of reach without AS.
Just stick to the basics train 1 on 1 off doing full body every time.
The biggest builders are SQUATS...........DEADLIFTS..........CHESTPRESS.
Allways work to max weight for 6 reps.....(GIVE IT A TRY FOR 6 WEEKS)

My advice:
Eat
Sleep
Squat
Deadlift

And eat eat eat. 5000 cals a day and keep your protein high as well.

eat more

try drinking a dozen raw eggs a day
