When it comes to running Test whats the difference in mg?

[werms]

Example most people run 500mg a week

if you ran 600mg or 750mg How is this more beneficial? Do you see an increase in strength/gains compared to someone running 500mg?
I can only assume you have more Sides with higher dosages.

Sometimes you have to up the dosages slightly every time you start a new cycle to see more noticeable gains

When I ran my first cycle I noticed around the 10th week I upped the dose to 675 from 500mg per week and by the 12 week I broke out with bad acne on my back
