The size of the drops in Progest-E will vary depending on factors such as the temperature of the solution and amount of pressure applied to the bottle. This makes it essential when discussing “drops” to identify the weight of the drop. For people who want to know exactly how much they’re using, we recommend using a scale that can accurately measure in milligrams.
In the past we described a “small drop” as a drop weighing 30-40 mg, which looks approximately the size of a BB. This size drop contains approximately 3.5 mgs of progesterone. Each 34 mL size bottle contains approximately 970 drops weighing 30-40 mgs.
