how can I measure testosterone levels in a randomish population (as in, not asking ppl who've tested their testosterone and thus likely have testosterone issues) for very cheap?

Male pattern baldness onset is correlated w testosterone levels. “At what age did you first start experiencing male pattern baldness?” should do it.

Measure BMI and fitness, they negatively and positively correlate with testosterone respectively.

BMI doesn’t take muscle mass into account. Could be 8% body fat and “obese”. Obsolete metric.

Places like mail order test kits for all sorts of things, including hormone levels, for pretty low prices. You could reach out and see if they’ll partner with you? offers cheap walk-in lab tests as well

Correlation to morning erections would be most reliable imo
That’s my canary for when I need to change habits/when they’re working.

Depends on how large the population, and on whether you only care about averages or also about distribution. There are testing kits for around 15 (blood, needs small amount) or 30$ (saliva). I've done it at parties, ppl are surprisingly keen on it.
