General Effects Notes
The effects of 4-HO-MET are usually compared to psilocybin/psilocin.

Routes of Administration
4-HO-MET is most often taken orally.

Addiction and Compulsive Use
4-HO-MET is not known to be associated with compulsive use and physical dependence is extremely unlikely. Because its use is so uncommon, no definitive statements about its use can be made.

[14 mg oral] "Pulse is accelerating [...] no fear or anxiety [...] emotional openness, alertness and wide-awakeness [...] subtle enhancement of color and depth perception [...] very very mild effects on heart rate and breathing [...] Drifting attention span [...] Sensual body energy and great curiosity [...] Stronger visuals with eyes closed than open [...] very colorful flowing waves and organic landscapes [...] details in wood-grain textures and interesting fabrics are swimming about in the way I've seen again and again from 4-substituted tryptamines and psilocin analogues [...] I feel like a god, powerful and attractive [...] tactile hypersensitivity can be felt [...] My pupils are fully dilated [...] I'm trembling [...] I have the feeling that time is slowing down and then speeding up again [...] positive, uplifting energy in the body." -- Exp 76397
[17 mg oral] "I was feeling extremely sick [...] had to control my breathing as to not throw up [...] suddenly extremely cold even though my palms were clammy and the rest of my body was hot [...] heart was beating extremely fast [...] I much feel better [...] had a stomach ache [...] I was sweating to death and clammy [...] The walls were twisting and turning)..." -- Exp 91175
[18 mg oral] "I felt a little giggly [...] anxiety began to set in [...] Nausea began to set in [...] my heart-rate and breathing felt strange [...] I began to have very negative and sad thoughts [...] begin to see the typical rainbow-fractals that looked really similar to what I've seen on shrooms multiple times [...] feels very similar to shrooms but a little different [...] I have very deep, and introspective thoughts regarding our existence..." -- Exp 91567
[27 mg sublingual] "Some time dilation [...] Intensification and bleeding of colors. A strange effect of straight edges seeming to flow to the right, into themselves [...] quite like 4-AcO-DMT [...] Very good closed-eye visuals [...] Bright colors, very complex designs [...] All the colors of the rainbow in spiralling, fractal patterns which changed at all times [...] It reminds me of the spiral fractal in MilkDrop (the visualization program for Winamp) [...] The overall vibe was very friendly [...]" -- Exp 63399
