Bloodwork first. I would also seek out therapy before jumping back on. The most important thing in my opinion is that your health is back. You want to make sure that your hormone levels are normal, sperm count, and overall mental health is good. I would tell you to get back in the gym without steroids and get back in the groove. The last thing you want it to only go to the gym while on juice. That's a bad habit that I see a majority of 16-25 year olds make every year. They hit the gym and the juice hard in March, then by August they are back to the old ways.
