I am just now doing 3 IU's of jin hgh. I take it right after I wake up. Since I work all day I am unable to take it in the middle of the day. Is it absolutely necesary to split the dose once it's over 3 iu's or can I just keep doing it all at once. I plan on hitting 4 iu's soon and want to make sure I am getting the most out of it. It's been 5 weeks now and I love the stuff so far.
