steeve reeves did experiment with testosteone and other products during the 40s and 50s. he DID NOT finish his career natural. he INDEED was natural at the beggining simply because the level of testosteone plasma he achieved hurt him more than helped him during the early 40s. he simply experiemtned once in a while whenever he got some in his hands.
as i said before he was REAL natural in comparisson to any "natural" athlete now days.
if you want to see bodybuilders/powerlifters who were built ONLY on food and traininng,, i suggest to look twards the very early 1900s. during 1910-1920 every one was 100% natural and only used food.
