As for Metracil, I believe it is a brand of Medical Grade
PMMA more commonly used in Brazil. In theory it should be effective in providing results similar to that of New Plastic & Artefill - however, its efficacy has not been documented for penile bioplasty on this forum. Its quality compared to the aforementioned brands are up for debate.
There are some threads both on the old forum (
Phalloplasty.proboards.com) as well as this forum that touch a little bit on the product. I believe Dr. C's office will offer a brand by request, but I'm not sure about any other bioplasty physicians.
Good luck and play it safe!
