When to drop GH?

[Nuteboy]

I had posted something about what gear I'm using as I prepare for the Jr. Nationals and I was told it's a good idea to drop GH around 3weeks.

Is this too soon as I was going to drop GH 2 weeks before contest. Reason I ask is that if I drop GH three weeks then I have enough GH to run 3IU's a day instead of 2IU's.

Thanks guys.
