If a small sample dilution. A methylene blue at 1% concentration is clearly labeled. Then a rough approximately but not necessarily precise is 1 drops methylene blue 9 drops water. Then this totals 10 drops. This means I will use just 3 drops of that, dissolved in water. it helps if B12 was taken. After long trial and error, methylene blue is synergistic with a b12. A precise calculation requires a different measurement, but for all practical purposes this is fine.
