In contrast to glutathione, NAC is efficiently transported into the cell where it is readily converted to L-cysteine for glutathione synthesis
Also, GH has been shown to increase muscle mass and strength after 3 years (Jorgensen et al., 1994) and after 1015 years (Elbornsson, Gotherstrom, Bosaeus et al., 2013, Gotherstrom, Elbornsson, Stibrant-Sunnerhagen et al., 2009) although no effect was detected on fiber type with 6 months of treatment on a different report (Cuneo, Salomon, Wiles et al., 1992)
