5F-MDMB-2201 is a synthetic cannabinoid (indazole family) very similar with MMB-2201. However, it has very powerful action (agonism) at both the CB1 and CB2 receptors.
Systematic name: methyl 2-(1-(5-fluoropentyl)-1H-indole-3-carboxamido)-3,3-dimethylbutanoate.
It is a potent indole-3-carboxamide based synthetic cannabinoid, which has been sold as a designer drug and as an active ingredient in synthetic cannabis blends.
This synthetic cannabinoid receptor agonist (SCRA) is structurally related to MMB-2201. Also, it has very powerful action (agonism) at both the CB1 and CB2 receptors.
It's highly potent, showing activity in sub-milligram dosages, unsurprisingly for a fluorinated MDMB. Apparently this one becomes very intense and sometimes difficult and scary for cannabinoid-naive or even more experienced individuals.
Nevertheless, it is potent at very low doses, perhaps even 1mg or less depending on bodyweight, metabolism, etc.
One user mentioned using 5F-MDMB-2201 at a dosage of 500μg and apparently experienced effects lasting up to the 8-hour mark. He compared it to, or in between, MMB-CHMINACA and FUB-AMB, but offered no more information beyond that.
Another, possibly more experienced user reported reaching the 'farthest depths of his mind' with it. Thus, he had a very good experience with it.
