Yeah, I rate it highly. I had shipping issues with one specific package that contained some BSI Deca. I had everything I needed for the cycle but the BSI Deca, so I went to another source that is on the pricey side, but outrageously quick. The one vial of Faizer Deca I went through was clearly better than the BSI Deca. I used it more for the effect on my joints than the strength gains, but I could feel a small drop off going to BSI. If the oil is really fluid, depends on the oil used and how well its been brewed.
