Edit- I see that you used a dummy address to make this review and it is not verified so I am unable to connect and help with your issues. I cannot provide custoemr service if you do not message me!
I am leaving my response below for others to read that are interested in cordyceps. I am hoping to update the gourmet products soon and I will take the ease of finding the guide into consideration.
I am sorry you had issues! Did you contact me when you received only 1 wedge, I am happy to send the other culture if it was left out.
Cordyceps is one of the most difficult fungi to grow and is not for beginners.
Did you follow the cordyceps growing guide that is linked in the cordyceps kit page that you ordered from? It is a starting point but you need to be familiar with general mycology procedures to follow it. I am not a site that teaches you to grow cordyceps. I offer a guide you can use as a basis. I would have been happy to send you the link if you couldn't find it on the product page, but as far as I am aware you have yet to contact me privately about your issues.
If you do not have a sterile environment and sterile technique when prepping the nutrient broth for LC (you did sterilize it right?) than there will surely be bacteria. The nutrient broth isn't provided sterile, so any introduction of bacteria would be either because of your technique/environment or you did not sterilize it properly. At no point do I say the cordyceps specific broth is sterile, so I am not sure why your expectation was for it to be bacteria free out of the packaging.
If you email me I am happy to send some more detailed instructions, answer your questions and determine where the confusion is and send new cultures.
