Copulins in a mix, does IJ still have them, and pheromones in cold weather?

Speaking to guys, what are your experiences with using copulins in a mix? And is IJ still made with copulins?

Anyone have any words of wisdom for using mones in a cold climate? I’m in northern Wisconsin and its often in the teens and single digits here. Do I have to compensate in any way for the winter months?

I’ve never tried copulins but I can tell you IJ used to have them in it but no longer does. IJ is one of my faves even without the cops. As far as cold weather, the mones dissolve slower into the atmosphere. However, I would assme you would be indoors most of the time and most likely it will be warm so I don’t see this as much of a problem.
