Consensus on 1-Test?

I'm getting an original large bottle of 1-test from someone who saved a caseful after the ban. I plan on stacking it with some test cypionate for about 6 weeks just for a strength boost. Unfortunately he didn't have the methyl version, which I know works well. 

Anyway, I was wondering if anyone knows how good the regular 1-test is. The product is esterified to survive first pass, and it’s also suspended in a liposomal matrix.
