My doctor told me 2cc's in the evening. what is the diffence from am to pm.
In the Morning, with a empty stomach - Your primed to go directly into fat burning mode.
Carefull what them Drs tell you, they went to school, but they dont use the stuff (Well FreakFest here does

)
You will get a extra measure out of your cardio in the AM w/ the HGH. It is noticible. Rapidly so if your lean to start.
Many say NOT to take it before bed, you'll make HGH naturaly in sleep anyway, so dont do it then is their idea.
Reaction can also be individual, but I'd try it like I described, it works good for me and others.
