Intramuscular injections are absorbed faster than subcutaneous injections. This is because muscle tissue has a greater blood supply than the tissue just under the skin. Muscle tissue can also hold a larger volume of medication than subcutaneous tissue.
If you are worried about how fast is absorbed, then I can see why intramuscular would be better. However if you are doing injections every day and for smaller amounts then I do not see why subcutaneous injections would not be a problem as well.
