if anything i would start low. if you start high you risk shutting down your natural production earlier than it otherwise might.
in saying that it's not something that i do. my philosophy is to get maximum results from minimum gear and try and keep nice even blood levels.
makes it easier to work out what level to run your AI etc at too.
i used to frontload back in the day. i just don't do it anymore.
use alot less these days.
i'd rather use less AAS and stack with peptides, slin, GH etc
