In another thread I drew a parallel between PE and running: to get 4,5” in 19 months would be equal to run 100 meters in 3 seconds.
The only thing I can imagine regarding spectacular results that someone can have a very severe case of enormous inner penis, apply a lot of efforts and get 2,5”-3” in 2 years. That’s theoretically possible.
I’m in the same boat as you are. I’ve gained roughly a 1,8” EL after 2 years and 4 months of a very consistent, length-focused PE, sometimes being on (or even beyond) the edge of over-training. That’s quite a good result. And if someone states that he’s able to grow at a rate 3-4 times higher than mine over a long period of time, I’m not gonna believe his empty words, especially given that he has a commercial project in PE.
