Not exactly.
In my personal opinion if you're taking between 2 to 4 units per day which is not much for hypertrophy either first thing in the morning or pre or post work.
Now if you're doing large dosage say 8 or 10 ius, I'd rather do it in one shot around my workout. I prefer post workout.
On none training days, I would do my shot close to bed time because the bigger dose does make me a bit sleepy.
Some are even doing 3 or 4ius wit every meal with insulin as well to keep BG in check.
Also GH works best when insulin is around. T3 plus GH plus Insulin is where true visual changes start happening almost daily.
After my failed experiment to go as high as possible with GH I could not handle more than 10 ius it made me very tired and sleepy.
8 units daily is still amazing. Im going to still try increasing the dose to 10 then 12 etc... Just out of curiousity.
If you can afford real GH in all honesty, it's a game changer. The fat just melts off, your physique starts looking more 3 dimensional etc...
