I see reports of several LAL blends being inconsistent. Aqua Vitae, Nude Alpha to name a couple. Perhaps adding Steve O's diffusion technology and adding scent directly to the bottle could help?

Where you putting the pheromones?
it's not rocket science if the pheromone are un unscented you need to add a cover scent or people will smell the pheromone and think u stink like ass.

Also the human body get rid of its heat through the hands mostly.
