I am a normal healthy male of 42.In Dec 2015 I got my first PMMA(around 5ml) since I am uncircumcised. Touch wood I havent seen any negative side effects so far.Me and my GF has been happy with the Girth gains.
We had discussed Circumcision few times but long abstinance post Circumcision is what never got me on that route or more PMMA.
I also read somewhere that more than 10 ml of PMMA has shown side effects in some cases.
Recently I came across HA(Juverderm Voluma) for both shaft and glans in UK. When I visited the doctor he wasnt sure if mixing HA with the PMMA in shaft would be a good idea. Has anyone had HA with or after PMMA.
Restoration who is not on anymore has HA over pmmma to correct aesthetic issues, but he didn\'t have his whole shaft covered, sorry if that is not much help. I have heard that it is actually ok but that is not worth much. Considering you can dissolve HA really easily I am not sure it is that big a concern. I dissolved 30ccs of it it that was in my Dick in my apartment in half an hour.
It is possible. It can be difficult to inject anything after PMMA with a blunt cannula, easier with a sharp needle( because of the increased collagen). No manufacturer of HA likes it being injected over PMMA. Mostly the worry is infection or any other problem. So it is possible - the injector just needs to be really careful with sterility and technique.
