I think that’s pretty good “out-of-the-box” strength. That’s probably about where I was 4 weeks into picking barbells up when I was 10 years younger than you are now. It took me another 3 years or so to hit 600. Maybe it takes you longer, maybe it doesn’t. Maybe you won’t ever hit it.
There’s only one way to find out if you will ever pull 600, but let me assure you of one thing. If you’re pulling 365 one month into deadlifting, you can almost certainly get…

FUCK
…by any normal standards. Without a doubt you can set yourself apart from most other men in your age bracket. I doubt you will have any regrets if you train hard and see where it leads you.
