I appreciate this! Its basically dogma in nootropics groups, Reddits, and discords that you shouldn't take mucuna because it'll lead to receptor down regulation.
I don't even know what to say to that honestly.
Mucuna is a very commonly used dietary supplement ingredient and it is in a lot of things. It helps with natural testosterone levels, helps control prolactin, and is in a wide variety of mood enhancing products.
It's ironic that you say nootropic groups say not to take it - yet its in the advanced version of the best selling nootropic in the country; not saying that product is the best nootropic because it isn't, I'm just pointing out the irony there. And its in that product at 1,000 mg. and you're questioning 100 mg. being in M-Test.
I'm not knocking you, don't take it that way - I like you - I'm just giving it as an example of how far Reddit and some groups can be away from real science, the real world, and sometimes common sense.
To put it in perspective, NOW Foods, one of the largest, trusted supplement companies on the face of the Earth - a company so strict and cautious that they won't even sell basic DHEA, sells Mucuna and deems it safe to take regardless of age. So, our grandmothers can safely take it - think about that for perspective haha.
There are hundreds of thousands of people that are on medications, sometimes two or three medications that affect Dopamine much more than Mucuna is going to.
The making a big deal about Mucuna is one of those things where sometimes people create problems that aren't really problems, just to have something to be able to write about.
