In a manner of speaking.
Most things, at least the ones I needed, as per usual.
However morphine was substituted for dipropionylmorphine, save for the very first dose of morphine, in the morning to restore me to my usual self, pain free and not in discomfort. That way I could function, and as such, do what was needed in the lab.
Dipropionylmorphine is SUCH a HUGE improvement over morphine or diamorphine; the latter being 3-4x the potency of morphine, roughly similar duration of action, but faster acting an.d somewhat different subjectively speaking. Dipropionylmorphine is as manyfold as potent as diamorphine, as that is to morphine, and both much much faster acting, a ton more euphoric, longer lasting (I'd get 6 hours, 7 at most from morphine sulfate or diamorphine but 15 hours, even 20 from dipropionylmorphine, from a single dose, compared to the 6-7 hours from morphine or the diacetyl diester) and if used IV, then there is less histamine release than morphine, still, more so than H. Which is just about right, because I like there to be some, just not too much, and IV, there is one HELL of a rush, and a delightfully warm fuzzy 'wrapped up in cotton wool' feeling afterwards. Plus faster onset, and the effects once the rush declines is still quite long lived.
Has to be, at least thus far, my favourite of all the Mu-opioid receptor agonists I have ever tried. Bar maybe oral methadone, although I've ever had that a couple of times. Intend to explore that one a little more soon. Still, dipropionylmorphine is one top-notch MOR agonist:)
