FUB-AMB (also called methyl (1-(4-fluorobenzyl)-1H-indazole-3-carbonyl)-L-valinate, AMB -FUBINA, AMB-FUBINACA and MMB-FUBINACA) is a synthetic cannabinoid of the indazole family. Like many of that class of chemicals, it is a powerful CB-1 agonist.

Structurally, FUB-AMB is actually a methyl ester analog of closely related AB-FUBINACA. The different chemical designation of AMB-FUBINACA indicates that in this case the valine terminal amide groups is omitted and a methyl ester substituted for it. There is very little publicly available research on the physiological effects of the AMB-FUBINACA variant, so it should be treated with a great deal of caution.

As a research chemical, AMB-FUBINA is of interest to forensic scientists and neurologists alike It is also a complex biochemical which can be of aid to certain mass spectrometry projects. Ready to buy AMB-FUBINA online? See the payment methods we accept here.

FUB-AMB Notes and Observations

ChemicalFrog makes this chemical available exclusively for research purposes. However, it must be said that this material has seen use as a recreational drug in recent years. There is little formal information available on the psychological or physiological effects of doing so, and this practice can only be considered very dangerous.

Known side effects of human use of FUB-AMB are said to include:

  • A strong sense of euphoria
  • An increased sense of emotional sensitivity or emotional connection to others
  • Enhanced, prolonged wakefulness
  • Decreased or suppressed appetite

Some users have reported a distinct philosophical turn of mind, and an increased tendency to complex, abstract thought.

Negative side effects have also been reported. These often include paranoia, anxiety, increased blood pressure, dizziness, nausea and possible blackouts. The frequency and intensity of negative side effects are said to be greatly amplified by taking alcohol as well. As with any drug, designer or otherwise, mixing its use with alcohol or other substances should be considered extremely dangerous.

FUB-AMB has been detected in a synthetic cannabis-replacement commonly called ‘Train Wreck 2’. This mixture has been linked to users suffering seizures even in the absence of a diagnosed seizure disorder. It is unclear if this effect is related to the presence of FUB-AMB, or one or more of the other chemical components of the Train Wreck 2 product.

Legal Perspectives of FUB-AMB

Recreational misuse of this research chemical has been linked to injury, illness and deaths, particularly in the United States.  For that reason, it is not surprising that at least one state government – that of Louisiana – has banned the chemical. Sweden has also classified FUB-AMB as hazardous, and it is being investigated by the law enforcement and medical communities of several other governments. Click here to see out terms and conditions.

Permitted Use

All ChemicalFrog products, are sold only for use as research chemicals. This is of course the case for FUB-AMB as well. It is neither intended for nor suitable for consumption by humans or animals, or for any clinical use whatsoever. It should be considered a potentially dangerous substance until clear research becomes available stating otherwise, if such studies should ever be forthcoming.Click here to see your shipping options.
