How Might PDA Work
I've done both of them
Remodeling (Strengthening the Structure): For months (sometimes even years), the new tissue matures, strengthens, and tries to blend in with the surrounding area to minimize scarring
Storage and Handling Packaging: Sterile Water for Injection is available in a range of single-dose sizes (commonly 5 mL, 10 mL, 20 mL, 50 mL, 100 mL vials, as well as larger bottles up to 1,000 mL for pharmacy use)
So injecting near the injury doesn't give you any extra benefit, and going intramuscular instead of subcutaneous just adds discomfort for no real upside
Think of them as biological messengers that help you heal, regenerate, and optimize your body naturally
