Hey brother, due to the long ester of the test e, you can inject any time of day and it will not matter. The oil you inect sits in the muscle and slowly releases over time. The release is very slow. Half life is around 1 wk. So inject any time of day you are comfortable with and have the time to do it right. Espeically, when you are new to IM injections, you want to be very careful and make sure everything is sterile.
