i would guess that Robbi did a very low amount of drugs throughout his career. he won his first national show july 19 1975. at the end of his career he didn't look much different. as bodybuilding became alot more influenced by drug intake, (evidenced by distended bellies and weird bodyparts), Robbi looked pretty much the same. they said his work ethic was unparrelled and he was never out of shape over30+ years. one of the top bodybuilders of all time. i would say the same thing about Vince Taylor.
