it depends on how much hgh your going to use, whats the objective... 2 to 4ui pharma you can take it at once. Even 6ui I tried... If you read some of my posts on HGH timing you're going to see that I recomend doing just as you said, for burning fat you should take it in the middle of the night, when you wake up for a piss, then go back to bed and sleep 2 to 3 hours until you wake up for the day...
If you want to see GROWTH, you need to take it to another level, somewhere around 10 to 20IU per day. Some take 30+ IU day, and of course, you'll need to split it in 2IUs doses or higher. To grow, they use it with slin, with some meals.
For Us, poor mortal, for fat burning, better quality of life, fuller muscles and a little growth effect, 2 to 4IUs is affordable, and even this dose can get you out of money!
Let me ask you something, this pic you posted, is some china HGH? Jin or similar?
I use hormotrop 12IU, and I get it right from the hospital.
