Honestly guys, all this stuff is bro science at best.
The most important thing about GH is quality & the 2nd is quantity. After that, it really doesn't matter that much.
I've tried pinning 2x, 3x, 5x a day. On an empty stomach, 30 mins before meals, with insulin, without insulin, in the middle of the night, IM, sub Q etc & IT DOESN'T MATTER.
All that matters is getting a good quality GH, using as much as you can afford & taking it about 3-4 times a day. it doesn't matter when, on a full or empty stomach as long as you space it out evenly through out the day.
