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”).

For more information on 4-HO-MET, check out our Ultimate Guide.

What are 4-HO-MET 20mg Pellets?

These pellets are a convenient way of accurately conducting research, without the need for additional lab equipment.

Each pellet contains 20mg of 4-HO-MET fumarate and they can be easily split in half if the researchers chooses to start their experiments cautiously.

What are the Effects of 4-HO-MET?

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: 

  •     Stimulation
  •     Spontaneous bodily sensations
  •     Colour enhancement
  •     Visual hallucinations – particularly of a geometric nature
  •     Analysis enhancement
  •     Fits of laughter and an increased sense of humour

Potential Side Effects of 4-HO-MET

  •     Nausea
  •     Muscle contractions
  •     Increased heart rate
  •     Excessive yawning
  •     Increased salivation
  •     Temperature regulation suppression
  •     Seizure


4-HO-MET is classified as illegal in:

  •     Germany
  •     Austria
  •     United Kingdom
  •     Sweden
  •     Switzerland

This list is not exhaustive, so do your own research into the legal status in your country before ordering!

Not gonna lie I expected to have to wait 3 months if it even arrived with how notoriously bad my country's customs is. It arrived perfectly though in just over a month. Super excited to order again!

So i had the worst experience with them ever. My order was not being able to be tracked down and when I contacted them they told me to check in with the post office myself. I did and got my package although it was empty and there was nothing in the packaging so the day of the party where I was supposed to use my order. did not happen so my friends were all high and I had to sit there sober because of their mistake. Upon contacting them, they replied days after and promise to double the order and send it. Well it did not happen when the order came it had the original order which was not doubled down.(eventhough it was promised ). Anyways I was scammed before so I decided to make a video before opening the package ….and u guessed it. There was nothing in it and it was caught on the camera. I wrote them an email which they have been ignoring from a while after more than a week I’m writing this review and hoping to get atleast my money back! I would suggest to avoid them at all costs!

I have made several orders at this store. Once the package was not delivered to me. Probably the loss of the carrier that delivered the package. Even though the package was not insured against loss, I was sent compensation in the form of a "gift" in the next order. When I pointed it out. The CC team communicates by e-mail, is happy to advise you and always accommodates your requests. The only e-shop that has soul and very good heart. Great shop, great team. Thank you very much.

Extremely fun to trip on, all though it’s just not quite the same as actual shrooms, i’d say it’s a pretty good substitute

1 month ago

This substance has become my favorite! A very smooth and visually beautiful trip, with almost no negative effects and a certain clarity of mind.

3 months ago

I was pleasantly surprised with this substance it helped me a lot exploring my inner world. It’s very helpful if you have depression because it improves mood a lot.

I was also surprised that the positive effects can stay for one or even two days. Unlike substances like MDMA it does not cause a comedown. At least not in me

The only downside is that It causes nausea, and if administered in high doses (20mg+) causes stress. My advice is to cut the pill in 4 and take a micro dose in the morning

Other than that highly recommended

I’m a huge fan of this substance.
very visual and not much confusion

Side effect majoritary some gastro intestinal issue, but that does not happen every time.

4 months ago

Very nice experience. As I expected it behaves for me as a more visual version of 4-HO-DMT (Psilocin) with a similar length and with less head space. My initial research with 10 mg was fine for a social environment. The subsequent testing with 20 mg showed me to true potential. I can suggest the substance in a quiet environment as a colorful experience though somehow lackluster in respect to introspection or as an “add-on” to other chemicals to make the experience more visual. I will definitely recommend this substance to fellow researchers.

Very nice substance. Works great both orally and insuffated. Feels like somthing in between lsd and mushrooms. It’s very recreational, not many deep thoughts, much of laughter instead 🙂

A very good product, funny and chill experience

Me gusta mucho el 4 ho met, sobre todo tomado un par de horas después de haber tomado ETH; ello hace el viaje más visual y profundo.

Ordered in dec. 2021. Good packaging and fast shipping. The product is interesting, a great visual experience without too much headspace.

Une montée très rapide, 20/30 min.
Et une durée assez courte 4h
Hallucinations tres géométriques. Il ne vaut mieux pas trop manger avant.

Fast onset and great reminiscences from the testing. Totaly going to test again.

Per quello che costano sono assolutamente da provare, hanno effetti visivi un po differenti dall’lsd e vari analoghi, è molto più geometrico.
La sensazione fisica mi è sembrata la medesima è me la sono goduta un botto insieme all’acutezza visiva che ti da, la pace mentale e fisica, veramente top sostanza

Cheaper and gentler than lsd with slightly different visualizations, but with a sufficient dose it will take you to the same “place”.

J’ai pu tester la substance dans mon laboratoire. Effectivement la qualité est au rendez-vous, pour le moment les retours qualitatifs penchent vers des hallucinations internes très colorées avec un seul comprimé.

A strange molecule, as powerful as it is surprising …
Keep cool and enjoy. Guaranteed trip :p

Excellent produit, bon dosage malgré le sujet hyper réceptif.
Tout le monde ne semble pas avoir les mêmes effets :
– musique sublimée
– excitation et énergie à bloc
– couleurs ultra pétante
et pour les chanceux :
– champs de vision déformée
– hallucination au point de finir avec des faunes et des filles aux bois de cerf en plein cœur d’une forêt sous une pluie de lumière.

Bought our first 4-HO-MET here at CC a long time ago and several times since. It quickly became one of our favorite tryptamines to research.
To me it’s kinda like acid and shrooms had a baby together. Best of both worlds, but also very unique.
Pellet form makes dosing easier, because of its potency.
Even 5 mg is noticable, but depending on the intention one may prefer 10-20 or even 30 mg.
50 mg is also recommended, although only for experienced researchers. And in that case, powder + a proper scale is a cheaper solution.
But these Lizard Labs pellets never disappoint.

Great visuals and lots of energy. Makes music more enjoyable. Highly recommand.

Great product and customer service. Very pleasant body high, audio enhancement and visuals. I personally recommend a quiet nature setting and try to avoid too much social interaction on doses 20mg or higher. 10mg would be a perfect dose for a beginner. 10/10 would recommend.
