Vein Visibility a sign of Growth?

Hey y’all, I’ve noticed I’ve got a significantly more bulgy flaccid with more vein visibility! Since I’ve been doing PE. My flaccid is about 5 or so inches but it’s fatter and I notice more prominent veins. I didn’t have any sexual activity (including fapping) for a few days and yesterday I totally noticed this. I’ve been on the Cum Holy Grail Stack as well. I do stretches in the shower and jelqing. I’ve dabbled with pumping a little bit.

So is this a good sign that I’m making progress? A sign of gains coming?

How long have you been PEing?

Consistently? About 3 or 4 months. I discovered jelqing in high school back in 2008, however, before I found Thunders.
