Theoretical maximum: it assumes complete decarboxylation (THCA × 0.877) and that every milligram ends up in the food. Real yield is usually lower, which is why you start with one portion and wait. Re-run the maths for your flower →

Dosing notes
Browning the infused butter directly would take it well past the temperature that degrades THC. Brown the plain butter, then add the infused.
Why both plain and infused butter?
Flavour from the browned plain butter, dose from the infused. Browning only the plain portion protects the THC.
Educational content, not medical advice. Effects vary with body weight, tolerance and what else you have eaten. Label infused food with the milligrams per portion and the date, and keep it away from children and pets.
