First time using ITW for my mycology specimen research needs. After the ease and privacy of order, from placement to receiving ( btw received a lot sooner than I expected so that was awesome)
Upon opening my carefully wrapped and protected research specimen, I inspected the syringe that was loaded with thick, clean healthy isolated B+. I now see the difference in quality I had been receiving prior to ITW and pretty ticked at myself for not using ITW sooner. I will be using ITW solely here on out for all my research needs. Thanks to ITW for living up to your reputation and helping to make mycology research with lab grade access easier for all.

Very rhizomorphic growth. Colonized quite fast and teases a plethora of possibilities.

Fantastic genetics. Of the different strains I purchased, these were the fastest I have worked with. Are there faster? Likely. Cambodians, Creepers, Ecuadorians, Z strain (etc) are all supposedly faster, but I was impressed by these and have never worked with those other ones. Very happy with this purchase.
