- For most shoulder injuries involving tendon damage, the BPC-157 and TB-500 combination represents the most researched approach. Adding GHK-Cu during the remodeling phase may improve the structural quality of healed tissue. For frozen shoulder specifically, relaxin-2 targets the actual pathology more directly than any other peptide, though availability remains limited. If you are exploring which peptides to combine and how many you can use simultaneously, our guide on how many peptides you can take at once addresses this question directly.
