4-HO-MET Fumarate Powder Product Info

4-Hydroxy-N-methyl-N-ethyltryptamine, or 4-HO-MET, is an intriguing psychedelic compound belonging to the Tryptamine class. This substance shares a chemical relationship with psilocin, the active component found in psilocybin mushrooms, commonly known as “magic mushrooms.” The synthesis of 4-HO-MET was first accomplished by Alexander Shulgin, who chronicled it in his influential 1997 book “TiHKAL” (“Tryptamines I Have Known and Loved”).


What are the Effects of 4-HO-MET?

Users often report that 4-HO-MET exhibits some similarities to psilocybin and LSD, although the distinctions are more pronounced compared to the differences between substances like 1P-LSD and LSD. Generally, 4-HO-MET is recognized for its shorter duration of action and is often categorized as a “recreational” psychedelic.

Some of the most frequently reported effects of 4-HO-MET include:

  • Increased stimulation
  • Spontaneous bodily sensations
  • Enhanced color perception
  • Visual hallucinations, particularly of a geometric nature
  • Heightened analytical thinking
  • Fits of laughter and an amplified sense of humor
