Just chiming in here, not to step on anyone's toes but a lot of typical internet misleading info here.
It will defenatly add results. GH is more = better, as far as you can handle the sides.
2-4iu = slow build up of elevated igf levels.
12iu = fast buildup of much higher levels of igf.
it's not more xyz than that lol.
I think 1 month heavy dosing is fine, and you should see results after one or two shots if you pay attention in the mirror. 3-4 shots of 10-15iu a week - same effect. Just take the whole dose in one shot, actually whenever you feel like throughout the day. bed,pwo,morning all have their positive effect.
You will gain water but the water will be in the right places compared to typical aas bloth, with that I mean it feels and look like its inside the muscles, make you feel full and tight.
The effect of the high dosing should continue at least a couple of weeks after before it wears of.
Many guys including Cutler incorperate high dosing regimes on/off cycle wise. It definitivly makes you recuperate faster after training and makes you able to train more/harder.
If you want and know how to use slin. use your max tolerate dose of fast acting slin with the gh shots. It will make you liver produce even more igf.
