He is not mistaken. He bought 15 mcg’s per spray and used 10 sprays which is 150 mcg
There is a few ways to do this but this is the method I use because its quick and easy once you get the hang of it and you waste less. Its like layering which is the prefered method but in a bottle instead of on the skin.
First buy some bottles the same size either to-go or the 30 ml Since your working from a 30 ml its probably best to get those. You need 2 bottles the same size.
I chill the bottle because I dont want any diffusion. This is not scientifically proven just something I do LOL
First empty bottle…Take your Armani and transfer some into the bottle size your working with. Your going to do this so when you spray your getting the same amount you would from the pheromone bottle.
Second empty bottle… Carefully line the spray nozzle of the P83 with the opening of the bottle. Spray 5 times into the empty bottle. That’s 75mcg total P83 in the bottle.
Now take your first bottle with the Armani. Spray 10 times into the Second bottle. That would cut the dosage to 7.5 mcg per spray.
If you spray your Armani 20 times into the bottle your at 3.75 mcg per spray.
If you spray your Armani 30 times into the bottle you have 2.5 mcg per spray.
Put the caps on your bottles right away. I let everything settle for about 1/2 hour then gently shake it to be sure its mixed good. I would do this before apply it each time but once after mixing should bind them. I just tend to shake them everytime when applying any pheromone or scent whether I mixed it or not. Its just a habit LOL
This should give you enough to test with.
OR
In a 15 mcg bottle there is about 3000 mcg of P83
That means there is 100 mcg per ML
Take out 1/2 ML with a pipette put it in your empty bottle. (same size)
That would give you 50mcg of P83. Now add 20 ml of Armani to that to get 2.5 mcg per spray.
Shake and settle.
See how you waste a lot less with the spray mix method then with the actual mixing method This way if it doesn’t work out for you you dont have a 20 ML bottle of 2.5 spiked Armani laying around
I dont know how you tested P83 or what reaction you were looking for but remember all pheromones dont cause attraction so you dont see hits all the time but they are effecting those exposed. Some cause behavior changes. Keep a eye out for those behavior changes. Especially in body language with P83. I think people make the mistake of expecting putative to all attract the target to them. In expecting that you can miss what they are doing.
My dose for P83 is around 25 to 30 mcg’s. It doesnt cause attraction though at least for me. I still love what it does do
