2.5 inches in 2 years would put you at the top of the class. You’d be on a statistical edge as thin as they come. If even 30% of people who put 2 dedicated years in got such results, then we’d be aswarm with 2.5 inch gain ruler pics. But we’re not.
I think 2.5 inches is a great lifetime goal for PE and the average dude (if he ever got there) could probably expect to spend 5 years getting there. And don’t forget, in 5 years of dedicated PE there’s a lot of ways you can fuck your dick up too, so there’s risk.
I think the best goals in PE are the longest term ones that allow you to just really relax into the process. If you can get your dick to relax along with you then so much the better.
I know it sounds like mumbo jumbo and etc, but in my personal PE experience, you’ve got to be able to cope with plateaus, quick unexplained gains, and be constantly listening to your dick in order to stay, “in the zone”. Sometimes being, “in the zone” means you do the work and don’t grow. When you place time constraints on it and push too much you lose your ability to think about the process and finesse it.
Dedication+finesse+consistency= success in my opinion. Tweaking your workout, fine tuning it, this is what gets you there.
Seems like most of the 2.5 inch gainers go through a “dead year” or two and then, almost as if to say, “I give up!” their dick finally coughs up another burst late in their careers to take them over the top and into the land of the Big Gainer.
