I've tried highadventure on Nucleus and his 100oz's were pretty bomb, but he has recently removed some of his listings. Only the powered shrooms remain and although at a great value (80 an oz) my clients prefer whole caps.
Any suggestions? Located midwest USA btw
Grow your own. Very simple and you can get the spores on the dnm. Sterilize everything really well as contaminants are the only thing to worry about.
