Opioid research chemicals

[DENGLAND3434]

Hello,I am a long time heroin user and have a decent size tolerance.

Im wanting to experiment with some opioid research chemicals.Ideally I would like to fine one that is most like heroin.The only ones I know about are u-47700 and u-49900 and then also some different variations of fentanyl.Is there any other ones that people recommend?Im looking for ones that are water soluble and able to IV.

Also can anyone tell me the difference between u-47700 and u-49900 in what kind of effects they have?If there are any.

Ive no idea where you could obtain these compounds now, but I found O-desmethyl-tramadol to be very like heroin. In fact it was better than a lot of street smack I've had. Plus it was very potent orally.
