That is one possibility I have heard. I have also hear as much as 1000mcg ED or EOD and then others take 500mcg daily. I havent even ordered any yet, so cant speak from personal experience, but you are talking about where I was probably going to start.
At least this will bump it for some better informed responses.
I take 1000mcg every day during the week and then lay off it during the weekend. I cycle it though too, so that I don't get too used to it and it looses it's effect.
