Could Marvin Eder have been completely natural as claimed? Experts doubt it based on fat free mass index studies and what they've come to know about the upper limits of natural human muscle and strength potential. However Eder was around when only crude,basic and largely ineffective testosterone pellets were only just synthesized,making it unlikely Eder, as an impoverished New York Bronx 18 year old,would have access to them . Look at his lifts and FFMI and come to your own conclusions. Or are we seriously underestimating what we are capable of naturally?
