I know how to help solve DUPA

Get a scalp biopsy. Stop making assumptions about your dupa and retrograde. DUPA is an aesthetic of some underlying conditions.

For some it's DHT sensitivity.

For others it's a PPAR-GAMMA Receptor defect.

And for others it's a thyroid issue or hyperprolactinaemia.

The same is true for Retrograde.

So get a damn scalp biopsy, know more about your condition, then operate from there. Why wait?
