i think in your early 20's a male would make around 2iu gh ed most of it being at night. so i dont see how taking 2-4iu in the morning would not help a young male. cause the early morning GH would have already of done its thing and the bodies negative feedback loop would have been reset to normal by mid afternoon. so he would still get his nightly pulse as usual. just my opinion. now everybody can hate on me for not running with the herd!
