Mr H, the dosage is relatively small anyway. And if you shoot the muscle 3 times a day, that is also pretty frequent. In my opinion, shooting less, but then shooting say 5 times a day, I don't believe it would be more beneficial.
With how shitty the pgf2a makes you feel, and the side effects lasting between 1 and 2 hours... I don't think you'd want to feel like shit 10 hours out of the day, anyway.
I saw no difference in growth from when I was taking a lighter dosage 3 times a day, than when I was taking a bigger dose twice a day. The pain level with a 1/2 cc shot isn't that much different that a full cc shot. So I couldn't justify taking the pain 5 times, when you could get away with taking it twice.
