I\'m reading the study on androstadienone and estratetraenol (the pheromones contained in Realm fragrances) on psychological states in Hormones and Behavior. The authors said that they obtained the compounds from Steraloids, Inc. They have a site at steraloids.com. On the site, I was able to find androstadienone for sale at 5mgm@$60. I guess Realm only patented the use of these compounds in fragrances, but it doesn\'t have exclusive rights to their sale. Has anyone ordered anything from Sterloads, Inc.? Chemist, are you there?
