Some people believe that in beginning of the growth hormone cycle the desired dosage should be gradually built to and gradually phased out when the person is ready to end it. From my experience it makes no difference whether I phase in and out or start and stop with full dosage. On the other hand, I do get a few days of blood sugar instability (sudden hypoglycaemia) when I end my cycles. Within 2 days to 2 weeks after my cycle is complete I get sudden hunger attacks (blood sugar drops). I keep a candy bar handy for such episodes. It happens about 3 to 5 times in the 2 weeks period.
