Mixing raw pheromones into cologne: how do I measure the dropper doses?

Androstenol
Androstenone
Beta-androstenol
Androstanone
Estratetraenol

I ordered these from another website months ago. They come in 10ml dropper bottles. So on Tuesday night, I decided to mix these in a 7.43ml cool water (cheap cologne from walgreens) just winging it and I had to best hits so far. The only problem is I have no clue how much of each I put in, and trust me i’ve tried agian with no success.

So if any of you has had experience with mixing pheromones please help me out. First off, I need to know what I can get to measure how much of each product I’m putting in. its a 10ml dropper bottle, with 10mg of each pheromone in them. But there is no measurement scale on the dropper.

Is there anything I can buy for measuring the mg??

How about a medicine dropper? The ones for babies have measurements in them.

Yeah, pipettes are cheap as chips! I got lots of them from an arts supply shop. Or a pharmacy will stock them too.
