Fairly in depth article on drugs in SA Rugby https://www.bbc.co.uk/sport/rugby-union/50785122 . I went to Craven week back in 1982. Was considered way too small was also told to gain some mass (wasn’t specified as to how. At around 15 stone and 6ft I was considered way too small to play flanker in SA. I realise that at those weights now (don’t I wish) that I wouldn’t be looked at but this was back in the amateur days. My first venture into Namibia (or South West Africa as it was then). We were all praying for the sort of rain we’ve been having here not played on a harder ground before or since.
