Time of Day to Stick?

I stick my legs. Sometimes it’s like butter. Sometimes it hurts quite a bit. Usually it’s somewhere in the middle. I think I’ve found it’s always easier in the morning. Maybe because I haven’t been walking around all day and my muscles are flaccid and unused? Has anyone else had this experience?

In the bellyfat before bedtime. Zero pain twice a week for over 4 years.
T injections always make me sleepy.
