I appologize, I didn't realize in the first post that your plan was to run 1.25g per week. If you've been at the level before without any trouble, then go ahead and front-load this time by doubling the first 2 or 3 injections.
If this is your first time at that high a dose, I think it would be wiser to just start injecting at 625mg twice per week and let your serum testosterone level build up more gradually.
