Yes, we have some excellent providers in So Cal. Please go to P-Long.com to find them.
As for men who have had fillers, P-Long is an excellent treatment option. I find that men who get fillers get what I call a pig-in-a-blanket penis with a thick shaft and small head. P-Long can help elongate the shaft. However, finding a doctor who uses ultrasound guidance for the PRP is essential. Injecting PRP in men with previous fillers can be tricky.
