Benefits of IM Delivery: Faster peak blood concentration Suitable for peptides requiring quick response (e.g., PEG-MGF) Useful for large-volume injections Drawbacks: Can be more painful Higher risk of tissue damage or improper injection Less ideal for long-term peptide therapies IM peptide injections result in rapid systemic exposure, but may lead to inconsistent depot formation and localized degradation.
