Having green mag and neovar is a bit weird. I would look at either Pslin or anabolic pump if you want a nutrient partitioner and just use green mag for creatine since you already have it. IGF-2 is a good looking product, but if you want something a like more cost effective, you could go with PowerFull, or even bulk 1-C.
I do like the idea of Xtend, or even better would be Purple WrAAth (or bulk BCAAs/EAAs to keep costs low). Leave the Leviathan out. Awesome product, but you've already spent quite a bit of money, and it had stimulants and forslean in it. You have enough of that in your stack.
