The Field Notes
From the founder

Why some men get noticed the second they walk in.

It isn't confidence. It isn't the jawline. Most of it is chemistry, and most men are working against theirs without knowing it.

A man spraying Bullitt No. 1 pheromone cologne
Two sprays is the whole intervention.

I spent years wearing cologne that did nothing.

Not "nothing" as in it didn't smell good. It smelled fine. It smelled like whatever the guy at the counter told me was selling that season.

But nothing ever happened. No second looks. Nobody leaning in slightly when I was talking. None of the stuff you're told is supposed to come with smelling good.

I assumed that was just how it worked. Cologne is decoration. You put it on, it sits there, it fades by two in the afternoon, you reapply.

Then I started reading about what actually drives attraction chemically, and I realized I had it backwards. Conventional cologne isn't decoration. It's interference.

Your body is already sending a signal. Cologne covers it.

Here's the part almost nobody explains. Your body produces pheromones. They are chemical compounds that come off your skin constantly and are detected subconsciously by the people around you. Research suggests they influence mood, perceived attractiveness, and how socially responsive people are toward you. You don't smell them the way you smell a fragrance. You just react.

That's your natural signature. Everyone has one.

Now: what does a bottle of department store cologne do? It sits on top of your skin and buries that signal under half an ounce of synthetic top notes. You end up smelling like a product instead of like a man.

The question I got stuck on wasn't “how do I smell better.” It was “how do I amplify what I'm already putting out instead of masking it.”

What we built

I brought in a clinical psychologist. Not a perfumer. Someone who understood the behavioral side of scent, because that's the outcome that actually matters.

What came out of it was bio-identical pheromones. Not synthetic approximations. Compounds that mirror the ones your body already produces, so your system doesn't treat them as foreign. They blend into your existing chemistry instead of competing with it.

Three steps, and that's the entire mechanism:

1
Applied to skin

Absorbed through the routine you already have: the soap in the shower, the deodorant after, the cologne before you leave.

2
Bio-signal released

The pheromones mix with your natural chemistry and amplify your existing scent signature. Yours, but louder.

3
Detected subconsciously

The people around you do not smell a cologne. They register a person.

No magic. No mystery. Just chemistry most men have never been told about.

“Sure. Does it actually do anything?”

Fair. I'd ask the same thing, and I'd be suspicious of anyone who answered too confidently. So I'll let other people answer it.

Bullitt is where most men start. Some take it further.

Bullitt is the cologne you reach for on the way out the door. The protocol is what's working on your skin all day underneath it. Soap builds the base. Deodorant holds the signal where your body heat is highest. Solid cologne concentrates it at the pulse points. Body butter is the one everybody skips, and it's what keeps the whole thing on your skin after the shower has worn off.

Wear Bullitt on top. Run the protocol underneath. That's the full picture.

Every kit comes in Bond, Maverick or Durden. If you don't know which one you are, that's the next section.

The signal only works if it's actually yours.

Three profiles. They aren't scents, they're postures. The scent is just how each one gets expressed.

Wear the one that's already true about you and it amplifies. Wear the wrong one and you're wearing a costume, which is exactly the problem I was trying to solve in the first place.

Still deciding

Common questions.

Is this actually science, or is it marketing?

Bio-identical means the compounds mirror what the human body already produces, which maximizes biological compatibility. Research suggests pheromones influence mood, perceived attractiveness and social responsiveness. Our formulas were originally developed with a clinical psychologist, and everything is made in the USA in small batches. We are not claiming a love potion. We are claiming chemistry, and that most cologne ignores it.

How long until I notice something? +

Most men report a difference in how people respond within the first two to three weeks of consistent use. Consistent is the operative word. One shower is not the test.

Will I smell it on myself? +

You will smell the fragrance. You will not consciously smell the pheromone, and neither will anyone else. That is the point. It is detected, not smelled.

Which profile should I pick? +

Take the quiz. It takes 60 seconds and it is more accurate than guessing.

Do I need the whole system? +

No. Most men start with the Essentials Kit. But one bar of soap on its own is the version most likely to underwhelm you, because the signal does not hold through the day.

What if it does not work? +
