History of the Koh Samui magic mushrooms

Koh Samui is an old school shroom with a rich history in the local Thailand culture. The strain was first discovered on a tropical island in Thailand named Koh Samui (hence its name) while growing on a mixture of sand and clay soil.  

Koh Samui shrooms have been used in Thailand for centuries as a therapeutic agent and important spiritual and cultural ceremonies. Over the years, this strain has made its way across the world and can now be found in Canada and other parts of the globe.  Koh Samui remains a favorite recreational choice among locals and tourists in Thailand. 


Fresh Koh Samui shrooms have a reddish-brown hue, which turns brown as the shroom dries. This is a medium to large-sized shroom with thick, long stems (up to 6.5cm tall) and wide caps (up to 7cm diameter). The caps take on a conical/convex shape, making them quite unique. These strains bruise easily, so some may have blue spots across the body.

Koh Samui shrooms have an above-average potency, placing them among the most powerful strains, just below the revered Penis Envy Psilocybin Cubensis. The strain is ideal for a veteran consumer looking for a new psychedelic experience. New consumers can also enjoy Koh Samui as long as moderation is practiced.

  1. About 5 minutes after I posted my last review about all the trouble I was having and that the 2 day Express Shipping took from Jan 4 – Jan 9 to reach me and that I was supposed to receive 1/2 Ounce Variety Pack of B+/Jedi Mind Fuck Mushrooms and that I only received the B+ Mushrooms, I received a call directly from the company. Talk about above and beyond. I thought at most I’d receive an e-mail. The guy apologized for all the trouble and “was going to make it right”.

    These guys are the real deal. Everyone makes mistakes but not all companies are so fast at responding. That makes me feel like my patronage is highly valued, which in turn makes me want to shop there again. I am glad that I took a chance on Think Mushrooms. I hope they’ll send me an e-mail or call and tell me what exactly they’re going to do for me.

    One thing is for certain, these guys will do as much as possible to make sure that they’re customers are happy with they’re purchases. I would and will definately use them again.

    On another note, the B+ Mushrooms I did receive were good, I would’ve preferred a more visual experience but I was very happy with the trip I had with the B+.
