pumping nuts and ball sac

Do you think we can have good gains with this and is it dangerous to pump your nuts is it painfull, i have a lot of question.

I check the pictures at monsternuts.com it’s incridible.

I prefer to pump my dick and ballsac separately, just so that I can monitor the individual results and gains better. I have pumped both together in larger size cylinders in order to multi-task, but again I prefer separately.
