Hi all, I did penile Doppler scan yesterday. Doctor injected PG1, and said he will be back in 10 mins. But after 10 mins, i did not have any hardness or erection. It was just bit bulged. I was shocked. And he concluded Vascular insufficiency and venous leakage. But I do get hard with manual stimulation or even get night time erection, whenever I get up inbetween at night, I do notice solid hardness. Only thing is, when I get Erection in day time, it won't be rock hard, and without stimulation it goes soft within 5-10 seconds. My hormones are normal/good. Is this because of low dosage? Or maybe some people don't respond to PG1?
