Is Pheni-B Ultra stimulant based?

No. Pheni-B Ultra is built around Phenibut, 5-HTP and Mucuna Pruriens, all of which sit on the calming and mood side rather than the stimulant side.

Phenibut is a specialist compound used in relaxation, calm and cognitive-support contexts, known in supplement circles for its calming profile.

5-HTP supports serotonin production and Mucuna Pruriens is a natural source of L-Dopa, the precursor to dopamine, so together they address mood as well as calm.
