So I have been working out weekly while on HGH. Every time I begin to workout, I get a sudden surge of energy that lasts for a good 45 - 60 minutes. After that time period, I will get exhausted (more than normal). I will go home and won't even eat, I will just crash on the couch or bed (whichever is closest). Has anyone else had this in the beginning phases of treatment with HGH? Just wondering if this is something that will persist or if it is something that is only present in the beginning stages of HGH administration.
