If you double your dosage, you are going to get better results. Simple as that.
If you're going to run 30mg per day, split up your dosage into a 15mg AM and 15mg PM dosage. You get 2 HGH/IGF-1 pulses each day instead of just 1 that way.
As for the hunger, I always take the nutrobal first thing in the morning or 30 minutes before the last meal of the day. If you take the nutrobal and then eat right after, you'll blunt the hunger response. Time your nutrobal so you eat 30 minutes afterwards.
