from my understanding the point would be to replace what my body should be producing naturally so for a 30 year old about 1-1.5 iu everyday..sort of like testosterone therapy does for people with low testosterone. I do understand Bodybuilders take far more than replacement dose and most people on the Internet talking about A minimum of 4 iu's A day are not on real pharmacy grade hgh and are probably on severely under-dosed peptides at best. This would be a lifetime commitment for me since my pituitary is fried.HGH is not going to do anything meaningful in the doses that a doctor would prescribe - Bodybuilders that get major results are using a dose several times higher than any clinic or doctor would ever offer. Plus it is extremely expensive and you have to commit to 6 months to a year of treatment to feel or see any progress.
