4-PrO-MET; the Tryptamine that’s taking the research chemical industry by storm!  

4-PrO-MET (4-propionyloxy-N-methyl-N-ethyltryptamine) is the O-propionyl ester of 4-HO-MET, meaning it converts to 4-HO-MET under certain conditions with results nearing virtually identical. .

Both 4-Pro-MET and 4-HO-MET are chemically related to psilocin, the active ingredient in psilocybin mushrooms (“magic mushrooms”). While 4-HO-MET has long been a research favourite, 4-Pro-MET is new on the market and available to a wider range of researchers (we’re talking you, Germany!).

Made By MindPort Labs

We spent a long time searching for a lab that shared our commitment to ethics and high quality standards. Many European RC “labs” rely on outsourced production in India or China and produce very harmful chemicals, so finding a manufacturing partner we could work with closely was important to us. So we’re proud to collaborate with MindPort, a high-end pharmaceutical lab (most of their work is done in the pharmaceutical industry) that happens to be run by psychedelics-enthusiasts. Meaning they have the highest possible testing and quality standards, combined with a deep passion for innovation in the psychedelics fields (you’ll see some exciting new products of theirs in our line-up soon!)

Responsible Research with 4-PrO-MET

There is limited information on 4-PrO-MET available online, however we can recommend reading this page as an informational source for interactions and measurements for independent study. We also encourage you to read individual reports so you have an idea of what to expect (also great for entertainment purposes!). 

Always have a responsible research partner present and practice good set and setting to get the most out of your experiment.
