Are you still preparing your hormones with ethanol and DMSO ?Heat the oil in a Pyrex glass. I do it Bain-Marie, but a Bunsen burner would serve just as well. Once the oil is hot, add the powder. Do this slowly to ensure full dissolution. Depending on the concentration you wish to achieve, you may have to stir with a magnetic stirrer or with a mechanical one, rather than by hand. Add the tocopherols while the oil is still hot. The volumes of the oil and tocopherols may not be additive, so more oil will be needed to adjust.
This is how I do my liquids. I do them with DMSO, ethanol and water, because oils just take too long to absorb and leave you sticky.
