I do not believe insurance can CANCEL your policy if you use drugs, I don;t beleive that’s legal. Hell I was heavily addicted to cocaine and my insurance and HMO Kaiser Permanente covered some in and out patient rehab for chemical addiction, was awesome!
However if you want to keep everything off the books, I would imagine you could find a cash doctor and not use your insurance, take them your bloodwork to review your high scores and explain about the hep c and why u cannot donate blood. Request a phlebotomoy, say you’re getting headaches or something (google symptoms of High hemotacrit). I would not be quick to open the dialogue about AAS use.
Maybe even try the CVS minute clinic. I got an allergic reaction to pinning some oils and I freaked out. I went to a CVS minute clinic and paid out of pocket (even though I had insurance) had them look at the rash and injection site. Admitted it was steroids, they tried to shame me for a second but they didn’t really care. Hell the male nurse told me I didn’t need roids because he was also a personal trainer and could help me (please fuck off thank you) then he told me to go see the Doctor and lie that I was using B12 shots I got online. ha! People can be cool.
Whatever you do, honest with your doctors or not, cash or insurance, just please do not drain your own blood at home, people die like that.
Start googling reasons why people might get a high hemotocrit besides steroids and make up an elabortare story. Look up the symptoms and say you get those. Hell you’re not asking for vicodin or controlled meds.
All of this is assuming you live in the USA.
Good luck!
