I like dfox's amento suggestion...but if dead set on going for strictly test boost, I'd prolly say AlphaMax, which has the added forskolin in it...that plus the ABE would put you at a pretty good dose on that...
Total edit, no AlphaMax...d'oh!!
Secondary edit: would probably save the addition of a test booster for another run, though I do believe DAA plus our newly released Inhibit E (a natural AI) would be a solid all around test boost...and both are reasonably priced...
