Definitely stick to the recommended dose at first then after a couple weeks you can increase but if your already feeling highly agressive you may want to take care. Try 1 pill ed if you do decide to increase. I went 2 weeks then added 1 ed and it made a big difference so I waited another 2 weeks and will add my sixth pill starting tommorow. Each time you up the dose be ready for some increased agression. Oh and I am weighing in at 227, I know weight is the primary factor but it is a factor.
