There were no significant differences in the levels of growth hormone (GH) for the G1 group, while showed a significant increase in the groups of G2, G3, and this increase was higher for a group of G2 than for G3.

Third, peptides may play a role in preventing the conversion of testosterone into estrogen, particularly in individuals with excess body fat.
