Can you inject peptides into scar tissue?
Skip it. Patient guides for shots under the skin say to avoid skin that is bruised, hard, red, broken, or has a stretch mark or scar over the spot. Scars and thick skin change how the liquid spreads and how evenly it soaks in. That is about the body, not a finding about any peptide this site tracks. Move to unused, healthy 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.
