sure....but im seems to make more sense if your looking for immediate absorbtion into the trained muscle...subq would cause the igf to be picked up quicker into the bloodstream which is not really what you want.... PLUS with the acetic acid in the igf i noticed that subq makes the inject sites sore and red (irritation) where as if you go atleast 1/4-1/2" in (IM) theres is no discomfort <-----this is my main reason for shooting it IM
