Preparation & administration
Intramuscular
Also known as: im · i.m.
Injection into muscle tissue, producing faster absorption than subcutaneous injection but requiring a longer needle.
In plain terms
Few peptides require intramuscular delivery. The belief that injecting near a target muscle produces local effects — "site injection" — has little support for systemically acting peptides, which distribute through the bloodstream regardless.
