Muscle gain and fat loss Direct assessments of CJC or ipamorelin on body composition are scarce, but numerous studies have linked increased growth hormone circulation to muscle gain and fat loss.13 By way of example, you might consider a 2013 trial that led to improved muscle strength after six months of growth hormone therapy in men over 50 years old, an age group likely to notice the effects of age-related muscle loss.4 14 You might also look at a 2014 paper published in the Journal of Molecular Endocrinology , which concluded that growth hormone exerts complex multi-system effects on skeletal muscle function ultimately to increase muscle mass.15 If not that, then perhaps a 1999 study that saw growth hormone recipients lose more weight and gain more lean body mass than their placebo-group counterparts.16 Other benefits of CJC-1295 and ipamorelin Along with their combined effects on growth hormone, muscle, and fat, CJC-1295 and ipamorelin may provide additional health benefits with varying degrees of scientific support: Injury recovery Remember, part of what makes growth hormone effective for muscle growth is that it increases cellular replication.1 Coincidentally, cellular replication plays a key part in a complex biochemical process that allows you to heal from an injury.17 The research is mixed as to the use of growth hormone secretagogues to facilitate injury recovery
