Hello Mel ..........
I have not experienced the pain of the injection itself ... although I have a cousin in much earlier stages of PCa than I, that had one injection earlier this year and said the same thing .... pain from the needle that lasted about one week.
I don't know the size (ml) of his injection - but he did have his prostate removed at least three years ago. And the highest his PSA (to my knowledge) has been since then ... was well under 0.5!
My injections were and still are every 6-months ...... or I believe 45ml shots.
Peace and wellness.
