Bear in mind I have both an A) extremely high tolerance, and B) a very rapid metabolism.
I can take 16mg of Bupe early, early morning (no later than maybe 9am). About the 12 hour mark after dosing my last film I have been able to get high on Heroin, reallll fuckin high. I dose half of what my morning dose would have been before bed, if I'm taking one, go through the night...
