I started to get very scared when I read Dr. jacobs most recent post where he sounds pessimistic and I thought this cant be insensitivity because i put on 20 lbs on testosterone and i have a libido and tumescence when on the test but i just cant get it up so i am thinking it is just something wrong with how the process for getting an erection works - something with the dopamine/norepenephrin balance or something since i tried the bromocriptine with the dopa precursors and the problems continued
I have been researching how Yohimbe works since it is so effective and it is an alpha(2) blocker.
Has anyone tried any alpha(2) blockers?
en.wikipedia.org/wiki/Alpha-2A_a … c_receptor
en.wikipedia.org/wiki/Alpha-2_blocker
It lists a few of the TRICYCLIC antidepressants
en.wikipedia.org/wiki/Tetracyclic_antidepressant
it breaks down how each of the options for alpha blockers bind to the a2

I found out more about alpha blockers here:
mayoclinic.com/health/alpha-blockers/hi00055
it says:
Alpha blockers relax certain muscles and help small blood vessels remain open. They work by keeping the hormone norepinephrine (noradrenaline) from tightening the muscles in the walls of smaller arteries and veins. Blocking that effect causes the vessels to remain open and relaxed. This improves blood flow and lowers blood pressure.
So then i google “alpha blocker erection” and find an article saying that not only do alpha blockers NOT cause ED but some patients reported 100% improvement in erections
