Copulins are a little different then your regular pheromones. The actual scent acts as a memory trigger.
The gay dude should not even have been affected by copulins in fact it should have repelled him as they do not like the scent or find it attractive at all. They are attracted to men.
The rise in testosterone only occured when men were exposed to copulins and a visual of a women. Also this thread may give you better insight of the mens point of view on wearing them. https://pheromonetalk.com/t/copulins-make-me-cocky/430
It has not been proven to raise it when worn by men. There is some sort of chemical reaction or a sensory reaction going on with copulins. You need both the women and the copulins. But more testing really needs to be done in this area.
Look up the Astrid Jutte studies for more info as well.
On a man it just smells like you just got laid. Plain and simple. Some women will look at that as your in demand and some women will be turned off by this.
Men have reported arousing dreams while using copulins but I believe the actual smell triggers this not a rise in testosterone.
You could wear a drop with AMMO or A314. It wont feminize it in any way but it will give a player bad boy vibe. Sort of the man slut. Some women may find that attractive others wont.
Keep testing though. I do suggest you dilute it some instead of wearing it straight you may have better results this way.
