I won't say this as an absolute as obviously there are going to be 1000 others who would quickly disagree. But, in my opinion the pro vs cons of anything over 500 FOR ME SPECIFICALLY is not worth it. I see no increased strength or muscle size that is directly linked to just more test. I have tried from 250mg to 2000mg and anything over 500 just really drove sides up more than it drove gains up.
I'd rather see 350test, 350 tren, and 300mast before I see 1000mg of test. Same mgs of gear but I promise you will look better, feel better, and be stronger on the 350/350/300.
I'm sure going from 500-1000 something in there happens and I don't think the gear is a "waste" BUT, it is not worth it in my opinion. I'd rather introduce multiple compounds that work together than heavy dosing 1 or 2.
Now with that you will literally find multiple men and women who say the opposite.
