Benefits of low dose vs high dose HGH?

[Sheen]

Assuming you are taking the same dosage 7 days a week for a long period of time, say a year or two. Are there any benefits to a low dose over a higher dose in comparison if your body is naturally low in GH production? And by high dose I don't mean crazy damage-your-body type dosage, I mean the highest dosage any certain company suggests vs a lower dosage the company suggests for a different indication.

Thanks much.

I've been on 5iu/ed for 4 years and I feel great. Is 5iu/ed high dose in your opinion?
