Great question. The bar for proof in biomedicine is naturally high. I only shared facts because so much is unknown.

If you can find a lab exploring the question, maybe you can support them by helping to raise money for experiments.

As a fun intellectual exercise, dive into the topic and challenge yourself to think about what kind of experiments could shed more light on the subject.

From what I recall, caffeine is mostly a concern for folks with pre-existing cardiovascular conditions.

Most adults can build tolerance, and I believe some studies are showing potential links between caffeine consumption and positive outcomes.

Of course, things get a little weirder with higher doses, and I am a bit concerned about new methods like pre-workout powder.
