I’ve been using my extender (X4 labs) for about 2 months and I just measured from 6.75 to 7 Inches in 2 months. I’m jelqing as well (only 100 jelqs ever other day in the shower)
I’m not using heat, I would love too but it would raise to much suspicious as I live with my family in a little appt.
I wear it 8-10 hours a day no rest days.
I suggest using heat if you can.
I’ve also been getting ridiculous rock hard erections when I get them. It’s awesome :)
