I am not disagreeing. I am merely stating that people throw around these numbers saying 1500 was normal just 10 or 15 years ago. That is simply not the case. These are ranges and that is the top end for men in their 20’s. They then extrapolate and justify running levels even higher because 60 or 70 years ago the average level must have been even higher. As has been discussed ad nauseam there are many factors for the decline in the ranges. Everyone points to environment, diet, sedentary lifestyle etc… These are clearly factors but you also must take into account the aging population. The average age of a male in the US was 27 in 1970. It is now 38. Of course the ranges will go down as more older people get tested. TRT also wasn’t a thing 20-30 years ago. There were probably plenty of 50-60 years olds will low levels just living miserably and not getting tested. Now we have 50-60 year olds getting tested and bringing down the average.
I agree with 95% of what you say but you keep using the argument that these 1000+ levels were normal just a few years ago. That is simply not the case. Definitely not for middle aged men. Will there be long term effects from running levels of 1000+ for 30 years? Who knows… What we have seen so far it doesn’t look like it. As you have pointed out it generally increases health and well being. Time will tell…
