Does it reach a point when this program is inneffective? Especially for someone who isnt a true beginner? if i were to run it do you think id see gains? I am not a beginner but i am not advanced either. I have been training for 2-2.5 years. My numbers are 440/300/515
Everything works, but nothing works forever. You will probably have some time before this program stops working for you.

With all the variables that differ from individual to individual, its really impossible to give you a definite yes or no answer. Try it for maybe a 4 or 5 week cycle, and go for new 5RM PRs during that cycle. I think it will be clear then whether or not it works.
If it were me, I'd just go straight to the advanced routine with the periodized cycles.
