I know your username establishes your criteria and motivation, and I\'m sure some of the PMMA experts can answer your question ... but if I had 5.25\" Girth I\'d also be asking myself if it was worth the undeniable risk. Good luck either way!
From my research, it seems to depend on how your body reacts to PMMA & builds collagen. I got .5\" out of each round (2), to get to my goal of 1\". That seems to be about average per round.
Age, diet, health, supplements, all play a part in how much collagen you build. There are even posts on here showing average gains.
I took Collagen, Vitamins A, C, & E, plus amino acids for 3 months after round 1 and gained .5\". After round 2, I took the same for 2 weeks and quit. I still gained .5\". So, it\'s a toss up.
*While I would never presume to discourage anyone from going through with PMMA (although I would argue that in my case, I NEEDED to do it) I would never have done it if I had been 5.25\". I was 4.5\" at my Viagra-induced best, and probably more like 4.3 or 4.4\" most of the time. So, I understand wanting to be bigger, but think clearly about it. You\'re already above average. Just my $.02
