You should always measure DCA by weight and NOT volume. Measuring by weight is the only accurate way to get the correct dosage, for this you need a precise digital scale.
Volume is how much space something takes up, for example 1/4 teaspoon is a VOLUME measure. The weight of a volume measure can vary depending on a variety of factors such has humidity and temperature. To ensure an accurate measurement of DCA use a scale. The scales in our store are accurate to 0.1 grams, this is accurate enough to prepare DCA dosages.
You can buy the scale in our DCA Store.
Here is a short video showing how to use the scale.
