I'm assuming you'd just take the sum of the known powder displacements and divide that by the number of compounds that you're using. Correct? I'm thinking there has to be a more accurate method to doing this than using the powder calculator. Besides, there are some compounds I want to use for which I cannot find the powder displacement or the density anywhere including Mast E and DHB Cyp. I saw a brief mention in a thread on here about using a graduated cylinder to get the most accurate doses but there was no detail on what the process would look like doing this. Can anyone provide some detail on how this would be done? Or if there is a better method than that? For arguments sake how wood the good folks over at Schering or Organon go about measuring their ingredients?
