I'm amazed that you are darkening, even slightly, after just 2-3 doses of 0.25mg.
Low dose and at 100kg/220lbs, yet you're a pretty big guy.
Me, I weigh less than 70kg even wearing my gym clothes. :p
Sounds like 0.25mg might not be as low as I'd thought,
but actually be quite powerful for someone my size and skin type (3).
