Okay, I am going to report my subjective personal opinion on this product from sublingual and subcutaneous injection.
Both applications had identical results.
I ended up using 500ug for both, and results were identical. I got most relief from pain, roughly equal to 100mg of hydrocodone. I experienced the standard opiate relaxation effect. However, I did not get 'euphoria' from the dermorphin, but I rarely get euphoria these days. I have used moderate levels of opiates for 3+ years daily for chronic pain. I don't recommend the doses listed above for any particular person, and especially not for new opiate users, those are simply the dose ranged ideal for ME. Using more, up to 1mg did not seem to make a perceivable difference. Duration was in the 4-6 hour range for both ROAs. I conclude the cost is too high to be practical.
My material I can assure you was pure and in tact and really was demorphin. I used a highly reputable bio-supply/synth lab that routinely supplies the materials used by reputable research facilities.
If one does want to get and use this material, I did find the method of using tiny capped sterilized vials containing a small amount of bacstereostatic water and the dermorphin crystals dissoved into these to be ideal. I stored them at -20C and removed a vial for each application. It thawed to liquid in a matter of minutes.
I can not report on IV use. It's not that I did not try, but I have terrible veins for IV use, even medical staff have a tough time on many occasions getting good access. I don't have damaged veins or anything, I do not and have not used IV injection on any kind of frequent basis. It's just hard as heck to see my veins and get a good stick; they are deep under my skin and difficult to locate, even the normal main ones; even my wrist; I can appear to directly contact a vein and not get access. I'll try again to IV, but so far the result has just been a bunch of annoying needle sticks. I'll add the conclusion of IV use if I accomplish that, or I may ask a retired nurse I know, but she would probably freak if I went to her and asked her to IV some experimental drug into me.
I know that placebo is a possibility. But I will note that I purposely let myself get into withdrawl and then used the dermorphin, and it had near total alleviation of symptoms.
