Working out on shot day

I've been on 2.5mg shots for the past 6 weeks and lost about 6kg. The side effects for the first 4 weeks were horrendous and I wasn't able to workout much. Now the side effects have dissipated, I've been slowly going back to combat sports and strength training. I still feel fatigued, but it wasn't as bad as earlier weeks. I'm about to take my 6th shot of 2.5mg and plan to train on the same day. Does anyone workout on shot day? What's your experience?
