It's harder for me to take the andro gel in the morning b/c I'm not on a set schedule. Is it okay to take the andro gel before bed?

I don't think it matters as long as it is on your skin for at least 6 hrs before showering.  I used to apply it in the morning; when I had an odd work schedule I applied it in the evening.  This summer I have been showering and applying it around midnight.  So no, I don't think it matters.  I haven't read the insert in a while, though, to see if it says anything about time.

Thank you.

Just going to second what Jay said. I often apply it in the evening because I sweat in the day and get sticky. I had my T levels tested when I was doing this regularly and they were "very good" according to my doctor.
