Just go to your doctor, tell him your taking anabolic steroids and that you would like to have blood work assessed.
You can't be reported to the police if your worried about that, confidentiality law protects you and he/she doesn't want to lose their job either.
My doctor always tells me to "stop because in his opinion it isn't worth it". I just nod my head, say yeah yeah and he either takes my blood then and there or sends me to the clinic below his office.
And yes, blood work will be covered by your provincial health insurance plan (god bless Canada).
If your doctor is a jew, you should have no problems whatsoever.
