Testosterone as a pheromone.

I went to see a friend of mine the other night. I was a little surprised to see he was about 30 lbs bigger than the last time i saw him. W got to talking and he said he had just finished a cycle of test enanthate. He said there are sources all over for raw materials and the prices are dirt cheap.

So pure speculation, How do you guys think testosterone would work as a pheromone?
