CONCLUSION
Several clinical trials have been conducted and completed to assess the safety and efficacy of GHS for the diagnosis and/or treatment of GH deficiency. Over the past two decades, scientists’ efforts have focused on the discovery and biological characterization of new tissue-specific SARM to promote the beneficial effects of androgens with greatly reduced undesirable side effects. In this regard, numerous studies with SARM of different structures have been reported. Despite evidenced clinical and preclinical studies, no SARM has yet received full clinical approval.
