how many cycles have you run bro. you are basing this info off of one cycle where you varied the test dose. in no way does this give you real world experience. i have run test at 250mg ew 500mg ew 750mg ew and a gram. i have done them all in separate cycles for extended times not just a few weeks. so i know and can tell you that the difference is huge. by your logic going from 500-750 made no difference so going to a gram from 750 would be no different. so a gram instead of 500mg is the same? makes no sense. I can tell you that every one of those cycles of different dosed test was way different and the increase is very noticable. me and dbbt have been running test for years now in different doses. noticing a big difference between 250mg to 500mg either was because you had just started to feel the roids period, or its in your head. though it wouldn't surprise me people don't see much off of 250mg ew but up near 400-500mg ew you really feel it. no matter what upping your dose for an extended time makes a huge difference.
