At 0, 3, 7, and 10 days, the tissues were fixed, and cryosections were used for in situ apoptotic staining with terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL), according to the manufacturers instructions (Servicebio, Beijing, China)

GHK-Cu was effective at a very low concentration
Proposed benefits: Accelerated tendon, ligament, and muscle repair
Based on the phase 2 and phase 3 trial protocols: Weeks 1-4: 1 mg once weekly Weeks 5-8: 2 mg once weekly Weeks 9-12: 4 mg once weekly Weeks 13-16: 8 mg once weekly Weeks 17 onward: 12 mg once weekly (maximum dose) The starting dose of retatrutide is deliberately low because the triple-agonist mechanism produces more intense initial side effects than single-pathway compounds
(European Journal of Pharmacology, 2018) showed BPC-157 accelerated tendon healing in rats by 65% compared to controls, with complete restoration of tensile strength within 14 days
