Using restorex along with Hink’s course

Hello all, so I’m using Hink’s course, and although he says “hey don’t overdo it” will adding restorex to my routine make it bad? I’m thinking of using the device for 60 minutes a day along with Hink’s hand techniques and pumping. But in the course he says you can do the hand/pumping twice a day and you can increase the duration. I don’t want my dick to fall off I’m scared
