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.
From what I have learned over the years of using and instructing others on pheromone use, Anone comes on a bit strong and aggressive for gay men and needs to be tempered greatly with some of the more friendly upbeat molecules.
A1 is a good choice but again you will want to include the softer molecules.
