Can you inject peptides in the same spot every day?

No. Reusing the same small patch is the strongest measured risk factor for lipohypertrophy in people on insulin therapy. A 2026 meta-analysis pooling 51 studies found incorrect site rotation carried roughly nine times the odds of that fatty lump compared with proper rotation. The lump then absorbs a solution more slowly and less predictably than normal tissue. Rotate. This is not a dose, a frequency, 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.
