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.
