The guy who gained the most and was on the stuff the longest used just the PGE-1 injections and gained 2 1/2". Laid off for a while then restarted with a mix of test(.5mg) and vasodialators with Potaba to gain another 1/2" in two more months. I just want to know how to get the Prostoglandin E-1 without having to get a prescription. Hey Doc I need PGE-1 injections to make my dick bigger. Any suggestions? How much does the PGE-1 cost?
