I'm wondering if anyone knows if there is any difference in application dosage between the samples and the full bottles that are sent in the envelopes from LAL? There isn't really any direction included for them, nor is there a dropper of any kind.
Hold the sample vial opening against your wrist facing upright. Now flip it upside down and right side up again while maintaining contact with your skin. Four of those flips are about equal to one drop from the full-size euro dropper.
