FDU-PB-22 is a complicated research chemical that can be of great use either as an identification sample or calibration aid for forensic or spectroscopic laboratories, as well as a chemical of use in a wide range of in vitro research projects. It is a close analogue with JWH-018, and particularly useful for labs in regions which have outlawed the earlier chemical dies to its use as a designer drug.

FDU-PB-22 is a strong agonist of the cannabinoid receptors. It is understood to have an affinity of approximately 1.19 nM for the CB1 receptor and 2.43 nM at the CB2 receptor. It is classed as a full agonist. In many ways it is similar to AB-FUBINACA, 5F-MN-18 and FUB-AKB48.


Does FDU-PB-22 have any side-effects I should know about?

FDU-PB-22 is a very new material, and there has not been  very great deal of formal research into its physiological or toxicological properties. From the in-vitro research that has been published, though, it is possible to surmise that the majority of anecdotal first hand reports of its effects on the human mind are fairly accurate.

In most ways, this material behaves like other indazole derivatives. The bulk of its effects come from its cannabinoid receptor actions, though it is likely that some of its metabolites have their own relevant effects.  It is understood to be a potent euphoric, as well as having the property of relaxing muscle tone.

These usage reports suggest the presence of a few negative effects as well. These sometimes involve paranoia or at least heightened anxiety in a minority of users. It can also be associated with mild nausea, or headache when its affects fade.


Is FDU-PB-22 legal where I live?

FDU-PB-22 is banned in Japan and Sweden, and is considered a controlled substance in Germany. However, to the best of ChemicalFrog’s knowledge it is not banned in any other jurisdictions.

It is, however, the sole and exclusive responsibility of the buyer to ensure that their order complies with all laws, regulations and policies of the delivery jurisdiction.
