Source comparison
What is known about local versus systemic injection?
Not proven as a clinical outcome advantage. Inject near the injury when it is easy and safe to reach. For hard-to-reach injuries, abdominal or thigh injection is the practical alternative. The peptides don’t "stay local" — they enter systemic circulation rapid

- Not proven as a clinical outcome advantage. Inject near the injury when it is easy and safe to reach. For hard-to-reach injuries, abdominal or thigh injection is the practical alternative.
- The peptides don’t "stay local" — they enter systemic circulation rapidly. But local injection may provide a higher first-pass concentration before dilution. Use injury-adjacent SubQ when the site is accessible and calm; use abdomen or thigh when it is not.
