Are you interested in the effects or hormones or of pheromones ? While related they are different and work by different pathways. Hormones work internally. Pheromones effect the neurotransmitters directly through the olfactory system and do not cross the brain blood barrier into the blood stream. Alcohol based pheromones are not absorb through the skin. Those manufactured to absorb through the epidermis work differently then Pheromones produced to effect the neurotransmitters. Again same substance different pathways. They are designed to diffuse off the body. So they will not effect the testosterone levels unless used on the skin in massive doses. Pheromonally… A1 is a patented molecule and you wont find any in labs in the USA. Love scent has some in there chem set section but I can not say if its pure or that he didn’t get it overseas. Others have used it with no problem though. Anone you can get here in the experimone section. Molecules obtained overseas are not pure or of high quality so you want to use US based labs. Androtics uses only pure US based molecules. Here are some studies on the subject of homosexuals and pheromones that may be helpful to you as well. > [@A1, EST in straight men, gay men and women](https://pheromonetalk.com/t/a1-est-in-straight-men-gay-men-and-women/80): > > [http://www.mindfully.org/Health/2005/Pheromone-Brain-Response17may05.htm](http://www.mindfully.org/Health/2005/Pheromone-Brain-Response17may05.htm) The testosterone derivative 4,16-androstadien-3-one (AND) and the estrogen-like steroid estra-1,3,5(10),16-tetraen-3-ol (EST) are candidate compounds for human pheromones. AND is detected primarily in male sweat, whereas EST has been found in female urine. In a previous positron emission tomography study, we found that smelling AND and EST activated regions covering sexually dimorphic nuclei of the anterior hypot… > [@Turning Homosexuality On and Off](https://pheromonetalk.com/t/turning-homosexuality-on-and-off/7423): > > [Turning Homosexuality On and Off - TierneyLab - Science - New York Times Blog](http://tierneylab.blogs.nytimes.com/2007/12/11/turning-homosexuality-on-and-off/) > [@Pheromone attracts straight women and gay men](https://pheromonetalk.com/t/pheromone-attracts-straight-women-and-gay-men/22410): > > Smelling a male [pheromone](https://pheromonelabs.com/) prompts the same brain activity in homosexual men as it does in heterosexual women, a new study has found. It did not excite the sex-related region in the brains of heterosexual males, although an oestrogen-derived compound found in female urine did. The testosterone-derived chemical AND is found in male sweat and is believed to be a pheromone. It activated the anterior hypothalamus and medial preoptic area of gay men and straight women alike.

A1 is a good choice but again you will want to include the softer molecules. Good luck with your research Tisha --- _[View the full topic](https://pheromonetalk.com/t/androstadienone-and-androstenone-research-on-gay-men-hormones-or-pheromones/33561)._
