I used it alot back in the day when I ran AAS...Loved the product, however with that being said, I have never seen so much as one result that would lead me to believe it is useful in a bulking phase. Like Nuk said, it is an asset to any cycle, this much is true, but...
It's expensive as hell, for your money why not just up your test. I ran 100mgs per day and loved it, but that was in a cutting phase...You are wasting your money using it in a bulk IMO.
