The potency I experienced was at least twice, perhaps three times what I am used to with material I have also believed to be of high quality. I always do cocaine with no tolerance, so fortunately that factor has been accounted for. However, I have not tried this batch without this potentiation regimind, so I cannot say for sure how much (if any) of the potency was due to the material itself.
That said, I think most of it is justifiably attributable to the Tyrosine + CYP3A4 inhibitor combination, just based on the pharmacology at work. In addition to greater potency and effect from a given amount, which I believe is mostly due to topping off dopamine stores with Tyrosine (though enzyme inhibition will help), the duration of effects from each dose seemed notably extended, a definite indication of the CYP inhibition.
As a bottom line, I think the materials used cost much less than the extra amount of material that would be required to emulate the effects, even if my findings are falsely optimistic for some reason.
