Ummm Bob darling, MX173 is the currant version of A314 without 2 or 3 pheromones.
Keep in mind that MX173 will hit harder and diffuse faster then its oil counterpart. I would suggest 1 to 3 spray tops but its hard to say with it still in testing. Also if you have some socials to soften it use those with it or stay low on dosage.
