I appreciate your response, but I still would like to know how regular of an occurrence it is for guys to get ed or dropped libido after their pct. I've built a huge base of muscle too I was originally 170lbs before I started out and was able to get to my current weight with 19inch arms naturally. Since I love working out I've always been curious about getting that extra edge through gear... Again this is still me being curious I'm still not completely sold on using or not.
