The HGH benefits are many, and this leads many people to abuse the compound. They believe if they use more, they’ll experience better results, but this is not at all the case. In fact, this is another similarity between HGH and anabolic steroids – both can cause severe side effects when used in high doses or for long periods of time. Per Dr. Alan Rogol, a representative of The Endocrine Society, HGH can weaken the muscles and cause heart disease when abused. He also notes that the bioavailability of oral HGH is too low for it to be effective, so those purchasing so-called HGH pills online are likely throwing their money away. Finally, per the FDA, excessive use can lead to a variety of cancers. This is why the use of exogenous HGH is so heavily regulated.
