Can high RBC cause lighheadedness/vertigo?

[Youthful55guy]

150mg/wk is really my sweet spot and what I normally run. If I do less than 150 I have trouble with sex drive/erections and doing more leads to high rbc (apparently). I went a little stupid the last few months going higher but I wanted to see what would happen and now I know. I'm not always the best at donating blood and my rbc usually hangs out around 51ish but like I said, too much test and too little blood donations led to me feeling like crap. As for 2X a week injections, I know that's the "normal" protocol around here and I tried it... and I totally hate it. Injecting 1x a week sucks enough for me. Lol

I'm curious, what are you using to inject? I find the 18G 1/2 inch needle of an insulin syringe to be virtually painless and takes me about 1 minute to draw and 10 seconds to inject. For me, E3D injections have been highly sustainable for about 6 years.

I was going to edit this, but I'll leave it up since it is rather humorous. I'm trying to envision an 18G 1/2 inch needle. What can I say, I'm really into pain! LoL. In reality, it's a 28G 1/2 needle!
