Ah the virgin receptors for opiates. I remember when 60 mgs of codeine was nice. Although I can still feel 60 mgs if I were not using kratom. But I have to say hydrocodone was weak to me, I always thought codeine was stronger. Even in the beginning it took a lot of hydrocodone.
But 10 mgs on a vfirgin brain will have you slightly warmed. Just be careful and use your knowledge drurrrrree. I asume you have read posts and will dig in. Knowledge is power.
I have virgin receptors for benzodiazapines, dissociatives, methamphetamine (only had it once). But opiates I do not have virtgin receptors anymore. It pays to keep tolerance low and monitor your drug intake.
