What is 4-HO-MET?

4-Hydroxy-N-methyl-N-ethyltryptamine, or 4-HO-MET, is a novel psychedelic substance of the Tryptamine class. 

4-HO-MET is chemically related to psilocin, the active ingredient in psilocybin mushrooms (“magic mushrooms”). It was first synthesized by Alexander Shulgin, who documented it in his 1997 book “TiHKAL” (“Tryptamines I Have Known and Loved”).

4-HO-MET is often reported to share some similarities with psilocybin (magic mushrooms) and LSD. Though the differences are much more pronounced and easily distinguishable than those between say 1P-LSD and LSD. 4-HO-MET is generally shorter acting and is seen as a “recreational” psychedelic.

Some of the most commonly reported effects of 4-HO-MET are:

Really great product and very potent! Has the most beautiful visuals from tryptamine class i’ve tried so far and the euphoria is nice as well. Plus it doesn’t have that serious headspace so it’s perfect for beginners with psychadelics.

Good quality, i recommend to use volumetric solution for make sure of the dose you make take to your plants. 3 or 4 mg can really change the experience.

best visuals I’ve seen with a product perfect
little or big dose can change completely your trip that’s why powder is the best solution

People make it seem like it is an easy going chem, but in my case I found it to be “emotionally complex” which can be beautiful but also challenging.

The best tryptamine, afetr lsd.
Visuals are more sharp then lsd, but it’s less introspective.

Very effective for visuals with less psychological consequences, meaning lower risk of bad trip.

Excellent tryptamine!

Always have good times with Metocin
Kinda euphoric, bodyhigh quite stimy, lot of laugh, and visual geometry, colors and distortions are very nice!
Headspace very handable in addition, not so tricky to research even in high doses.

Kicks ass. Great visuals, pretty light headspace (no paranoia, confusion or thought loops), decent music appreciation but not the longest legs. Will keep researching 🥳🥳🥳

4-HO-MET is a perfect substance to start with psychedelics, easy going
Be careful with serotoninergics potential interactions

Fascinating substance. Comes very quickly to the peak and holds it for a pleasant time. It is not exhausting and so easy on the headspace that it always kept in control. The visuals I would compare similar to the Lysergs. Would say 70/30 visuals / headspace. Creativity can be pushed a lot. Bodyload is in the absolutely acceptable range. Overall, highly recommended.

4-HO-MET is absolutely amazing it feels incredibly smooth and has the most amazing visuals of all tryptamines for me.
4-HO-MET has less confusion than other psychedelics for me which makes it more recreational while it still can go deep.
4-HO-MET is overall a mostly visual experience which is the appeal for it to me I absolutely recommend everyone who hasn’t done this one yet to give it a try and I recommend you insufflate this substance 😉
