I took 200mcg (that's 5 0.04mg tabs) of Hubei and felt N.O.T.H.I.N.G (my receptors were fresh by the way). Also, I doubt there are fake Hubeis out there. Also, my partner who took the same Hubei I took though he's gonna die from just 3 tabs a day.
So poantrex mine were real Hubeis. I wouldnt say that anyone that does not respond go 200mcg is considered having fake clens.
