My husband is trying both this and Lion's Mane for his MS. HUGE shoutout to Birch Boys for not being one of the companies that forces a subscription on people. My husband kept getting fed ads for a mushroom mix on his social media, but would have had to commit to monthly orders, and for many reasons we are not interested in that. We'll continue to buy from Birch Boys and are so thankful they don't force consumers into rolling costs! Also, this seems to be an even better product than anything we've seen advertised. Seems like they put their money into making quality instead of trying to force quantity.
