Although there have been no clinical studies linking increased HGH levels to weight loss, studies do link optimal HGH levels to supporting lean muscle. Plus, a revolutionary HGH-boosting supplement – SeroVital ADVANCED – contains the patented Smart Release compound that boosts metabolism and supports fewer cravings. In a clinical study, subjects using the key ingredients in SeroVital ADVANCED reduced their cravings for sugar and lost a significant amount of weight in 8 weeks.
