Sad that this should happen to Luke. I remember when he appeared on the scene earlier this decade, becoming a pro and moving from Australia to compete in the USA. He always looked huge and jacked. I remember also when he used to Train with Hide, Flex Lewis, and Milos at the latter's gym.
Surely he must have been doing something else all along that contributed to his kidneys/health failing faster than those other guys. You can tell they went head to head when it came to anabolics.
Shame it should happen to such a nice young bloke who was always friendly and helpful on the forums.
