Who writes this
One doctor. Every article.
I’m Dr. Nirosh, an MBBS-qualified physician registered with the Sri Lanka Medical Council, currently training in Sports and Performance Medicine. My clinical days are spent on musculoskeletal injury and rehabilitation.
I also trade, and I game. That combination is the reason this site exists. Most health advice is written for a sedentary average — it has nothing useful to say to someone who spends eleven hours a day locked onto a screen with money or rank on the line.
Nothing here is ghostwritten and nothing here is a sponsored placement. If I recommend something, it is because I would say the same thing across a desk.

How these articles get written
1 Sourced first
Claims about physiology, risk or treatment are traced to peer-reviewed literature or a recognised clinical body before they are written, and the source is linked in the text.
2 Reviewed by a physician
Every health article is written and checked by Dr. Nirosh. Where a topic falls outside his scope, the article says so plainly instead of guessing.
3 Corrected in the open
When something is wrong, the article is updated and the change is noted at the top rather than quietly edited. Email corrections to drnirosh@thedopaminedoc.com.
4 Independent
No paid placements and no undisclosed affiliate relationships. If that ever changes, the disclosure will sit at the top of the page, not the bottom.
