Can you inject peptides into scar tissue?

Skip it. Subcutaneous patient guidance tells people to avoid skin that is bruised, hardened, red, broken, or sitting under a stretch mark or scar over the intended spot. Scar and thickened tissue change how a solution spreads and how predictably it is absorbed. That is anatomy, not a finding about any peptide this site tracks. Rotate to unused, intact skin. This is not a dose or a protocol. Full walkthrough at /injecting.

Educational use only. This database summarizes published research and is not medical advice. Where a dose appears it is a record of what a trial or clinic ran, or what people describe doing, with its source attached. Nothing here is a recommendation for personal use.

Part of injecting: sites, needles and safety. Subcutaneous vs intramuscular, site rotation, lipohypertrophy, needle length and gauge, vial hygiene at injection time, travel syringes, scar tissue, and when to stop and see a clinician. Full walkthrough at /injecting.
