Will human growth hormone increase libido?
For athletes and bodybuilders who are no strangers to injecting testosterone based steroids, HGH will have minimal effect on libido. They are used to big fluctuations in sex drive (high when they start testosterone, low when they complete the cycle) so the increase from growth hormone will be mild in comparison.
For people not used to steroids, the HGH caused increase in sex drive is quite noticeable. There have been several studies on growth hormone's effects on libido. The results can easily be looked up on google.
