Some patients need both, some just one

More severe injuries may require the full eight week protocol or extended maintenance dosing

It is one of the most actively researched peptides in published preclinical literature, frequently cited in models exploring tissue repair signalling, gastrointestinal mucosal protection, tendon and ligament research, and angiogenic pathway behaviour
