It's pretty easy to spot the fakes with the anti-counterfitting measures Brovel labs has designed into its packaging. Personally, I think they produce some very low grade product and it's not something I'd choose to use unless it was literally the only thing I could get. The famous (often radical) under dosing issue is really the last straw for me - I like to have some reliable idea of dose when scheduling, and having differing lots tested is not always very practical.
