Vaginal DHEA (OTC)

Listening to this podcast from over a year ago where Dr. Irwin Goldstein recommends vaginal DHEA which will then convert to both testosterone and estradiol. Has anyone tried this? I take 10 mg DHEA orally daily, wondering if vaginally provides more benefits? Dr Kelly Casperson and Dr. Irwin Goldstein - DHEA discussion starts at 14:00

EDIT: I am specifically looking for info on inserting Over The Counter (OTC) DHEA tablets vaginally, not the incredibly expensive ($300/month) Intrarosa. The podcast above has details. Looking for anyone who is currently using OTC DHEA and their experience.
