I don't think OP is suggesting they be taken at the same time. The answer to the question however is that would depend on the stimulant being ingested. If it is an amphetamine like adderall, there isn't that much cross interaction in their pharmacology. Adderall (amphetamines) in ADHD medication based doses primarily act in increasing dopamine in between neurons while psilocin is primarily acts on serotonin and its receptors. While there might be some compounding sympathetic nervous responses at standard therapeutic doses it is unlikely to cause any noticeable side effects.

There are more supplements. You better do your own research on these:
- Tyrosin - Theanine - Creatine - Protein - 5-HTP - GABA
At best they might help, at worst, you wasted your money. PS: Have you tried fish oil (or perhaps algae oil) and zinc? According to the findings I provided, they might help you too.
But regarding the supplements or nutrients omega-3 & zinc. They do help. I provided the findings. Meditation also works.
Some links supporting my case:

Key points I made out of these links above:
- Mindfulness/Meditation - Omega-3 (EPA > DHA) - Zinc - Protein - Exercise 30 min/d (walking, calisthenics) - Low sugar, caffeine, and carbohydrates - Schedule/"game plan" (calendars, task lists)
I am also disappointed with how this "Ask HN" of mine unfolded. It is perhaps my fault. I should have clarified things from the start. My intention was to (prematurely?) optimize self-help strategies without medication, but my point wasn't well taken it seems.
