What's the informed consent route?? I don't think I've heard of this.
What I did, is that there's a clinic up in NYC my friend told me about. I had set up an appointment for testosterone consultation. When I went there, he talked to me about what I need to start, I needed my mother, and a letter from my therapist etc. We went over some stuff with testosterone and he asked me about my past and what I hope for the future. I then went and got bloodwork done the same day and he sent me home with the consent paperwork for my mother to look over. It talked about everything that T does, and I mean everything. My next appointment my mom signed the paperwork and he talked about everything on the consent sheet and the effects of T and opened up questions. After that he went over my test results, and then I got my prescription and I went home. My next appointment is when I got my shot.
The lady that drew my blood was very good. I didn't feel it one bit. I do hope it goes the same for you. It shouldn't be that bad! Hopefully you wont feel it. Just drink a lot of water so it's over with quickly. If you're not hydrated it'll hurt and the blood wont come out as fast.
I'm also nervous with my doctor. He seems so intimidating. Apparently I intimidate him as well! My friend goes to the same place and we talk about eachother with the dr at times lol. So don't feel nervous! It'll be fine.
If you're nervous when they check your vitals your blood pressure might sky rocket so try to calm down. That's what happened with my blood pressure. She did it again and I was fine, though. Good luck!
