As I always point out, you can and should switch to a doctor who will support you, not berate you. This does not mean a pro-AAS MD, but rather one who understands that you will do whatever you decide to, and he or she can only try to help minimize the health effects.
In terms of bleeding disorders, DO NOT begin injectable AAS use if you have hemophilia without talking to your doctor.
Hemophilia, as I am sure you know, means that blood clotting is in some way inhibited (there are various types and severities, so hemophilia is a class, not a condition specifically), leading to excessive bleeding.
IM and Sub Q injections are often used with hemophiliacs, but only after assessing the severity and type of hemophilia. If you were to hit a blood vessel, and are not on the proper-clot inducing medications and supervision, such a mistake could be dangerous.
This does not mean you can never inject AAS, but please talk to a doctor before doing so. Be aware that nearly any good doc will try to talk you out of AAS use, will try to give you a list of health risks, etc. But a good MD should and will support you, even if you do something that is a health risk.
In terms of contraindications of AAS use with those who suffer from hemophilia, I am not aware of any other than IM injections. There is some information linking AAS and hemophilia as causes or risk factors of compartment syndrome. Having this condition while using AAS may increase such risk.
A good doctor should be able to tell you any and all increased risks.
