[3] Intramuscular injection, or more specifically peri-lesional injection near an injured tendon or joint, has been used in animal models to test whether local delivery produces superior effects compared to systemic dosing

Retatrutide Clinical Research Findings The clinical development program for retatrutide has produced compelling data across multiple research endpoints: Weight Loss Efficacy: Phase 2 trials showed dose-dependent weight reduction ranging from 8.7% at the lowest dose to 24.2% at the highest dose over 48 weeks Metabolic Improvements: Participants demonstrated improvements in glycemic control, lipid profiles, and blood pressure measurements Safety Profile: Gastrointestinal effects (nausea, vomiting, diarrhea) were the most common adverse events, occurring in 60-80% of participants but generally rated as mild to moderate in severity Sustained Effects: Weight loss continued throughout the trial period without evidence of plateau, suggesting ongoing metabolic benefits These findings have positioned retatrutide as a leading candidate for advanced metabolic research

The results differ significantly by administration route: topical serum, topical post-microneedling, and supervised subcutaneous injection produce different outcomes, with injectable 503A compounded GHK-Cu producing the most consistent and comprehensive results in clinical settings
GHK-Cu, on its own, is hard to use and is typically an ingredient mixed into a formula
