In reply to Daniel Heath:
What are you trying to achieve? You're profile lends itself to sending tougher objectives on rock?
Sounds like a pointless stress on the body to achieve something that could be realised through healthier means and to a better more sustainable degree. In my experience bulk is neigh on redundant for climbing specific strength.
Also, don't underestimate the importance of quality carbohydrate - will be far more beneficial recording strength gains than an above average protein intake. Your body will be running on reduced blood glucose and no doubt craving muscle glycogen. Gluconeogenesis, the process to convert protein to carbohydrate for aforementioned purposes, is a poor economy and can lead to excessive nitrogen in the body.
Stevie Haston has a propper grip on things, pun intended - check his blog.
Reside at your optimum climbing weight and always be your strongest I rekkin. Any weight gained will almost certainly be offset by increased strength this way.
