I can't speak for T-Shots, but P-Shots are regularly offered in some
Male Enhancement clinics worldwide. I don't believe there is any merit to them enhancing or creating any new
Girth, but it is plausible they may be useful in post-op recovery (which PRP is known to do in other applications), which in turn can potentially yield better results. That said, many men have had
Girth procedures performed successfully without the P-Shot, so it's not like a necessity. It's more like a "it-can't-hurt" kind of supplementary treatment.
