I doubt I’ll ever order from anyone else. 1st class service and support + they get back to you however you choose to contact fast AF. Always going the extra mile to hook it up and let you know they appreciate your business. 🥇🐐💉

Very fast delivery and the best genetics I have tried. All of the shroomery vendors suck. All of the Reddit vendors suck. I got ripped off by two vendors on Spore Swaps. None of them compare to TMC. I either got no growth at all or contamination from shroomery vendors and spore swaps vendors. In 7 days my spawn bags were ready for break and shake with TMC genetics. Don’t fall for what anonymous accounts on Reddit or Shroomery say about vendors. Those types of reviews are absolutely untrustworthy. You don’t know who it is that is posting. For all you know its competitors. These people at TMC are talented and deserve each and every customer that becomes a long term buyer. Like me.

Thick Spores has the best liquid cultures around. I’ve sampled just about everyone over the years. Thick Spores has the most diversity in their catalog and the highest quality cultures I’ve ever worked with hands down. Their customer service is first class as well. I caused a shipping error with an order and Tommy really looked out for me, and they didn’t have to do that because it was mostly my fault. I don’t leave reviews often but these guys are really really good. If you’re thinking about giving them a try, do it. You will not be disappointed.
