Hey brother, sorry to hear about your health issues. Sadly yes, all gear is going to thicken blood. We get that great high endurance feeling from the added oxygen from increased RBC. I’m no doctor so I don't want to give you false info but what I would consider doing is looking into growth hormone and GH related peptides. I’m not sure if this will have a negative impact in your situation but it could possibly be the one direction you have left to consider. Otherwise, sadly bro, I would stay away from AAS unless you can find a Dr that will work with HRT and watch you closely. You can do a lot with optimal levels if this is an option. The key would be to find a Dr that will keep a very close eye on your labs
