So, i was pretty reckless last week and gone through 50 mg of this stuff which i have gotten it as a free sample with an order of butyrfentanyl.
It was like smelly yellow wax and dissolved easy in a solution of 45 ml destiled water and 5 ml of 96% ethanol.
I had been using the butyrfentanyl 2 days prior, so i had some tolerance, i dont really know how my last dosage of b-f was, but i think it was about 1-1,5mg(didn´t had tolerance beforehand).
Im not sure what drove me to sample this stuff, but ive prepared a solution of 1mg/1ml and started with about 50 µg, had no effect, upped it to 100 µg and got effects at around 250µg.
I mainly dosed nasally, rectally did not seem to have the good bioavaliability as nasally.
The duration was about half as short as the duration of butyrfentanyl, it was not as sedating but made me nauseous as fuck. I was pretty close to puking the whole day doing the stuff. For me, it was not as pleasant as butyrfentanyl. Euphoria wise it was en par with b-f.
I noticed a steep rise in tolerance. I started in the morning with 250 µg and in the evening i dosed about 1mg. At about 9 o´clock in the evening i had done all the 50 mg i had.
The thing that really suprised me was, that this stuff even put butyrfentanyl in its place. I had about 10ml left of a 1mg/1ml solution of b-f left. wanting to sleep after a long day laying on the couch and feeling nauseaus i wanted to sleep, so i took the remaing b-f solution titrating up from my last dosage of 750ml per nostril. I got only threshold effects from the whole 10ml of the solution, which i dosed in about 45 minutes titrating upwards.
I think the furanylfentanyl was about 4 times stronger than the butyrfentanyl, but please dont take these dosages as a guideline, both substances could have been of a bad purity. I also had tolerance, so i think a good starting dose without tolerance should be around 25-50µg or less. Its better to start low and work your way up.
Take care, be safe.
