A full-strength pheromone cologne in sandalwood bourbon, built on the Grondyke Alpha Blend in a 10ml roll-on that fits a pocket. Roll it on clean dry skin at the neck and wrists and it holds for four to six hours. It is designed to be layered over the matching Durden bar soap, so the profile is already on your skin before the cologne goes on top of it. One 10ml bottle is about a month of daily wear, which makes it the size most men use to find their profile before buying the 100ml.
This one is built on the Grondyke Alpha Blend, developed by a clinical psychologist and pheromone expert and then blended into our masculine scents. Each blend targets a different set of traits, which is what separates the profiles from one another. Bio-identical, so it mixes with your natural chemistry instead of masking it.
Patch test first: leave a small amount on the skin for 48 hours, then watch the area for another 48, 96 hours in total before regular use. Then one pass at the base of the neck and one on each wrist. Do not rub it in. Roll it on again once through a long evening if you want the signal back.
One 10ml roll-on cologne, bottled in the USA. Free of parabens, sulfates and phthalates.
Free US shipping over $75. Orders out the door in one business day. If it does not work for you inside 30 days we refund it, whether the bottle is full or half gone.

The Durden profile
The formula that
started the company.
Durden is the heaviest blend we make, the one Grondyke was built on. Its proprietary pheromone formula is paired with Sandalwood Bourbon for the man who intends to own the room rather than work it.
A roll-on is the format you actually carry, so the signal goes back on the moment it starts to fade. It goes on over skin already washed with the matching Durden bar, so the profile is reinforced rather than replaced.
The situation
Late rooms, high stakes, and the nights you do not intend to blend in.
The effect
Dominance rather than charm. People give you space and attention at the same time.
Pairs with
Durden soap, deodorant and body butter, same Alpha Blend throughout.
The scent
Sandalwood bourbon. Warm and unhurried.
Sandalwood softened with a bourbon sweetness. Warm and rich, with a boozy edge that reads closer to a bar than a bathroom.
What it reads as
Warm and rich
Sandalwood with a bourbon sweetness, and a boozy edge through the middle.
Where you know it from
Durden 2 soap
The same scent as the Durden 2 bar and solid cologne, in a new format.
Built on
Alpha Blend
The Durden pheromone formula, the same blend as the original Durden.
What are pheromones?
Attraction has a chemistry. Cologne usually covers it.
Pheromones are chemical messengers detected through scent rather than smelled. They shape how people read you before a word is said.
Only 10% of men secrete an abundant amount of them. The other 90% wash what little they have straight down the drain every morning. Ours are bio-identical and built into the lather, so the signal goes back on with the soap.
Bio-identical means they work with the chemistry you already have instead of masking it. Nothing is added to your routine. You wash the way you always have, and the signal goes on with it.
You will not smell them
Pheromones are detected, not smelled. What you notice is the scent and how people respond to you.
It is the whole line
Soap, deodorant, body butter, solid and spray cologne carry the same formula, so layering compounds it.
The Grondyke difference
The cheapest way to find out if this works.
Only 10% of the male population secretes an abundant amount of the pheromones women respond to. Most grooming products do nothing to put it back.
Ours replenishes it. Made in the USA in small batches with the cleanest ingredients out there. 100% of women are looking for 10% of men. Our soap puts you in the 10%.

Three ways in
Start small. Size up when you are sure.
The roll-on is not a trial size, it is the same cologne in the size you carry. It is just also the least expensive way to find out which profile people respond to. Three ways in, depending on how sure you already are.

I did not believe
it either.
Eight years married, then divorced, and suddenly back in the dating scene. A friend told me to try pheromones. I thought he was joking. He was not, and I have been building this line ever since.
Soap came first, because you use it every morning without thinking about it. The cologne came later, and it is the strongest thing we make: the same formula a clinical psychologist mixed for us, at full concentration, in the format you reach for right before you walk in somewhere.
Wear it for a month. If nothing changes, email us inside 30 days and we refund you, half a bottle gone or not. Return shipping is on you, no interrogation.
The details
Good questions. Straight answers.
Still unsure which formula fits? Take the 60-second pheromone quiz.
Take the quiz →Will people actually notice?
Pheromones are detected rather than smelled, so nobody will say "nice pheromones". What people notice is the fragrance and how they respond to you. The blend amplifies a signal your body already sends, it does not replace it, and nothing here is a guarantee.
How much do I use?
One pass at the base of the neck and one on each wrist, on clean dry skin. Do not rub it in and do not add more. It carries further than you think.
How long does it last on the skin?
Four to six hours for sandalwood bourbon, longer on fabric. Durden holds longest, Maverick lifts fastest.
How long does a 10ml bottle last?
About a month of daily wear. That is the point of the size: long enough to know whether a profile is yours, small enough to keep in a bag or a glovebox.
Which profile should I start with?
If you already know how you want to be read, pick that one: Bond for credibility, Maverick for approachability, Durden for presence, Bullitt when you do not want to choose. If you do not know, the 4-pack sampler is built for exactly that, and it costs less than four singles.
What is in the 4-pack?
One 10ml roll-on of each: Bond, Maverick, Durden and Bullitt No. 1. Wear one a week and you will know which one people respond to before you spend on a full bottle.
Should I patch test?
Yes, as with any cologne. Leave a small amount on the skin for 48 hours, then watch the area for another 48, 96 hours in total before regular use.
How is this different from the 100ml spray?
Same fragrance, same blend, different range and different size. The spray projects across a room and runs eight to twelve months; the roll-on places the scent where you put it and lasts about a month. Most men start here and size up once they know which profile is theirs.
Do I need the bar soap too?
No, but it is how the line is designed to work. The bar puts the profile on your skin in the shower, the cologne goes on top of it, and the two reinforce rather than compete.
Will I be able to smell the pheromones?
No, and neither will anyone else. Pheromones are detected rather than smelled, so what you notice is the Sandalwood Bourbon fragrance and how people respond to you, not the compounds themselves.
Can I put it on a subscription?
Not this one. Durden 2 is a first release and ships as a one-time purchase. The Bond, Maverick, Durden and BULLITT No. 1 roll-ons can all be put on a delivery interval if you want one on a schedule.
Shipping and returns?
Free US shipping on orders over $75, and most orders arrive in 4 to 5 days. If it is not for you, email us inside 30 days and we refund it, full bottle or half gone. Return shipping is on you.
