I haven't found a comprehensive list (If you have, please share) so I'm working on creating a list of substances that upregulate the different dopamine receptors, d1-d5.
This will have the substance, the dosage if I can find it, the specific receptors that are affected, and at least 1 link to a study showing the upregulation. Please keep in mind that I am a tech geek. I know computers and networking, not brain function or chemistry. I promise to do my best and with your instruction, together we can make this a real resource.
If you have any substances that you'd like me to research, please leave a comment below. Thanks!
