I think Dianabol is the goat if you want size, but make sure you stick at 20 mg or less, especially when you're stacking with testosterone. You don't want to go overboard.
Trenbolone is the goat. You should definitely try it out. I'd go 350 mg myself. I'd go 8 weeks. I'd stack 50 mg a day of anavar with it and some testosterone.
Pigsy is definitely the real deal. He knows how to throw around the iron and he knows his stuff on steroids. Look forward to seeing him on many podcasts.
