When aiming the goodly generous (indeed rather extravagantly generous) 5ml rig loaded with a preeeety damned concentrated solution of dipropionylmorphine, the fine needle I used (31ga) slid right in and hit the aimed for vein first time without more than a slight pinprick sensation in terms of pain. And owing to the small needle bore, it means the solution must go in slowly, a bit inconvenient really unless one's hands are steady, but it also means that the contents are delivered slowly and steadily, so with an opioid of considerable strength indeed, that can mean that the rush, once sufficient is administered to cause it in the first instance, is sustained by what is in essence, a short-lived infusion, in practical terms at least, so its sustained for quite some time.
Lovely, so far in my entire collective experience with any opioids, DPM is, with one other also containing it, the absolute rolls-royce of MOR-agonist opiates.
Wonderful smooth, long lasting, warm and fuzzly, relaxing as hell, fantastic legs, good muscle relaxant properties, makes a given quantity of morphine sulfate spread out a lot longer without spreading thin on the ground, and turns a pretty good opiate into a truly delightful one:)
Lol, I almost nodded off earlier into my bowl of golden grahams haha.
