Fast shipping and strong genetics. Never had a problem with contamination. If it’s hot out make sure you choose UPS air shipping. USPS messed up my shipment and my liquid cultures arrived DOA. Tommy replaced my order and sent it UPS 2 day air. Those were good! I won’t make that mistake again with living organisms during the summer. Thanks for the great customer service Tommy!

Thank you for the great review Randy! We are very happy to hear everything from start to finish went perfectly for you! That’s awesome! We hope to hear from you again!
Each syringe was Thick with mycelium. Just as advertised! I've never received LC syringes with that much mycelium. Excited to begin testing with what looks to be very strong genetics!

Thanks for the review William! We truly appreciate you! You’re the best! ✌️
I was skeptical at first because of the low low prices during their “gas and groceries cost too much” sale. But in the end I got high quality liquid cultures that proved to be viable and contamination free on agar. The myc is ripping through grain right now and is very rhizomorphic. Thick cultures turned out to be one of the top dawgs in the myco industry! Shipping was also fast same day shipping

Hi Matt! We truly thank you for your time you took to leave us a great review. I’m happy to hear that our competitive pricing saved you some money! We hope to serve you again!
Thick Spores exceeded my expectations by far! This company is exceptional and Tommy the owner is a true down to earth dude. I am not a noobie at mycology. I ordered the panaeolus cyanescens discount 3 pack bundle. Before I paid I contacted Tommy the owner about a few questions I had as they had a couple strains I had never heard of. Tommy answered in mere minutes and we chatted for a couple of hours. He showed me some resources about the strains I was ordering and helped me learn more about them. I bought two of the three packs in the end to support Tommy and his employees. I received 8 pan cyan liquid cultures from Thick Spores and all 8 produced clean mycelium free of contamination! I grew them out and all I can say is the genetics were amazing. Thanks a lot Tommy I look forward to talking to you again sometime ✌

Thomas, WOW! Thank you so much for the detailed review! Reviews like yours truly help other people. We are all so happy to hear that you love our work! We strive to provide our customers with nothing but the best. Thanks again we truly appreciate your kind words 🙏
I just wanted to say, as of now I'm a 99.9% satisfied customer. The Thick Cultures customer service, (particularly handle by CEO Tommy) were on point with the assistants and generosity when the packing department mixed up my order. It's good to know that Thick Cultures are willing to make sure their customers are satisfied with above average customer service. Along with the high quality LC's and wide variety of genetics and strains, their products are highly recommended for mycology and microscopy studies and he stands by his products. Which shows the love and dedication everyone should be looking for in a supplier. Again, thank you for making this right and of course for the bonus genetics as well. You will see me again soon enough. Best regards, Cayers23

Our dealings with Thick Cultures, formally Thick Spores have always been far above normal. Exceptional quality and superior customer service is a tough act to follow. I’m pleasantly overwhelmed by the variety of cultures available with new ones constantly emerging. Did I mention that we love this company?!?!
