It looks like you’re very well covered for your powerlifting meet. The only possible addition could be <a href="http://www.t-nation.com/store/products/gpc-fast-acting-shot"target=“new”>GPC Fast-Acting Shot to increase explosive power. Just take a capful 90 minutes before your first lift.
For your deload week, adding <a href="http://www.t-nation.com/store/products/elitepro-minerals"target=“new”>Elitepro Minerals before bed would be a good choice. It makes sense: if you’ve ramping up for a meet, you could be depleted in key minerals, which is common in those getting ready for a competition. It would also ensure you’re getting restful sleep.
Elitepro Minerals may be all you need for sleep. The magnesium component will help you sleep if you’re running low due to intense training. <a href="http://www.t-nation.com/store/products/z-12"target=“new”>Z-12 is perfect if you’re having obvious sleep difficulties, which can happen when you’re peaking for an event. I’d suggest using it the night before the meet at least, just to insure you’re fully rested.
Your <a href="http://www.t-nation.com/store/products/power-drive"target=“new”>Power Drive choice sounds good. It makes sense to take care of neural recovery in a deload week. Christian Thibaudeau is a big fan of Power Drive for that purpose.
