You have no idea how bad it really was. I am not small by any means as back then I was 120kg with no fat and still looked like a shrimp. The guys I played with in the army were all on it and went on to play for International teams. I didn't notice it so much then as that was under 20's and could hold my own comfortably. In the open division the following year I had a team mate jet off to Italy for 6 months and he came back twice the size. He made the Natal and Springbok team the following year. I wasn't tempted though as I know it has side affects and what was telling then was the pimples on the guys backs. It was hard not to notice in the showers how many guys had the tell tale signs. This was just as rugby was turning professional in 1991 so 4 years before it was officially a professional sport. Back then we were being paid drinking money but some of the guys were on heavy pay packets already. No wonder I struggled playing 2 matches per week plus 3 practice sessions leaving me with little to no recovery time.
