Decided to get tested. I'm 30, 5ft11, 185lbs. I've been lifting pretty consistently for 3 years. 2.5 plate bench, 4/5 plate squat and dead. I eat like shit, and I have done shift work for the past five years, so I often sleep during the day. I also edge to porn for hours at a time, pretty much every day.
My results were 19.6 which I think is about 580 by the U.S measurement. Studies from the 1990s pegged average test at more like 600+. And here I am lifting heavy for years and still below that. Pretty dissapointed desu senpai but it's made me keen to sleep and eat better. I'll test again in a few months and see if there's a difference.
