It is the prevailing view in epidemiology that the age-related decrement to GH & IGF-I activity is an evolutionarily conserved mechanism to promote lifespan primarily by staving off diseases of aging, like cancer/neoplasms that depend on cell # as a precondition to mutagenesis and is rooted in observations such as that individuals with larger body sizes tend to die significantly earlier than their smaller age-matched counterparts. This winding down is reflected by GH/IGF-I axis regulation of the adolescent growth spurt where 3.6 IU/day GH secretion is common versus 0.33 IU/day GH secretion being normal for an aged (50 years old, ±) 70 kg man of average build.On the flipside, many preclinical models of reduced IGF-1 signaling show improved longevity. HGH may improve many some things in the here and now, but probably not gonna make me live longer. Gotta weigh costs, benefits, goals, etc.
@Type-IIx thoughts?
Many studies on this which I can link if anyone's interested.
