ED, EOD: What Does It All Mean?

I know that ED and EOD refer to differing means of drug administration, but that is all I know. What do they actually mean? What, if any, other routes or methods of administration are commonly used? And, if such other methods/route exist, how are they abbreviated? Thanks.

ED - Every Day

EOD - Every Other Day

E3D - Every 3rd Day

Those refer only to injection frequency.

There are only really two types of injections that are used in the administration of either AAS or peptides:

IM - Intra Muscular. In the muscle

Sub Q - Subcutaneous. Under the skin.

Thank you.
