These internet chocolates never contain mushrooms according to everyone I’ve known or read about who have had them. If you’re lucky you get 4-aco-dmt which is safe and hard to tell apart from the real thing. This is an unregulated market and no one else cares about your health. Be careful out there.
I went through something similar and had my blender sitting for a while. Then I had kids and decided to get on the smoothie train again.
What I found regarding blandness was never add ice, never add water. Use whole milk or heavy cream or half and half. Unflavored yogurt is good and tastes like fruit when blended with frozen fruit. Bananas turn into a smooth thick liquid when blended. Frozen Bananas are often recommended but don’t help texture as much.
To summarize, frozen fruit is already bland and cold, don’t add water or ice. Skim milk is water for this use case so avoid it.
