The mitochondrial NAD + pool, with a higher concentration (~250500 M), is an independent source since the mitochondrial membrane is impermeable to NAD + and NADH
Given that the PG promoter is a potential target of the -catenin-TCF-4 pathway 18 , it is reasonable to infer that PPAR/ may regulate PG by activating this pathway
This state can also trigger Metabolic Conservation, where mitochondriathe cellular energy factoriesdownshift energy output in an effort to conserve fuel in response to perceived stress

Known and possible concerns include injection-site reactions, hormonal effects with certain growth-hormone-related peptides and simply not knowing what long-term daily or weekly use does because most human data covers short windows, not years
