How would the gains be if someone in there low 20's was to run HGH alone at 6IU's for around 6 months with no AAS?

Could you plz explain in these catagories....

Strength/Muscle gain/Fat loss


I know It's a young age etc. Just wondering what the gains would be like even though I'm not really concerned about HGH's effects in that way.

+ What are some good legal supps that work well with HGH?

Thinking about useing Creatine, L-Glutamine. Is there any others that work well with it?
