01 / the molecule
an invisible language
pheromones are scent-borne molecules that move below conscious smell carried on the air and picked up through the senses, the way attraction always has been.
02 / the signal
chemistry, made wearable
we pair copulins - molecules studied in connection with human attraction with a soft vanilla-and-oil base that warms with your skin.
03 / the response
presence, before words
some things are felt, not explained. wear it and see.
the honest details — when it kicks in, and what to expect
when it kicks in. the oil needs about 15 minutes of body heat before it starts diffusing, and one pass carries up to 12 hours. most people notice the shift over the first week of daily wear, not the first hour.
what it feels like. it is read below conscious smell, so nobody smells pheromones — they respond to you. warmer eye contact, easier conversations, a second glance.
what to expect. it works with your chemistry, not instead of it — it turns up what is already yours. every body is different, which is why you get 30 days to find out how it works with yours.

two passes per point
roll twice over wrists, neck, and behind the ears. press skin to skin — don’t rub, it breaks the oil down.

apply before leaving, not in the car — the oil needs a few minutes of body heat to start diffusing. one pass carries up to 12 hours; reapply before an evening out.

under perfume, or instead of it
copulins work below the scent layer, so your usual fragrance sits cleanly on top. solo, it wears as a soft skin-close vanilla.

how do pheromones work in humans?
pheromones are chemicals our bodies release through skin, sweat, and other secretions. they travel through the air, get picked up by other people's olfactory system, and influence how they perceive us — usually below conscious awareness.
so unlike perfume, which works on what people consciously smell, pheromones work on how people feel in your presence. copulins, the molecule in sirense, are among the most studied human pheromone compounds, associated with shifts in attraction, mood, and how warmly others read the wearer.
what does it smell like, and can i wear it with my perfume?
on its own, a soft, skin-close vanilla. copulins have a distinctive scent of their own, so for the first few seconds after you roll it on you may catch a brief hint of it. once the formula meets your skin it settles into warm vanilla, and that's what you and the people around you will smell.
under perfume you won't notice it at all: copulins work below the scent layer, so your fragrance sits cleanly on top.
what's in it, and is it safe for sensitive skin?
three ingredients: fractionated coconut oil, vanilla essential oil, and copulins. no alcohol, no parabens, no phthalates. it's vegan and cruelty-free — all three are plant-derived or synthesized, and we don't test on animals.
if you have particularly reactive skin, a patch test on the inside of your wrist is always a good idea.
how does the 30-day guarantee work?
every body chemistry is different. wear sirense daily for up to 30 days from the day your order arrives — if you don't feel the difference, write to us and we'll return every penny. no forms, no questions, no returns shipping. one email is enough, and you keep the bottle.
how long does one bottle last?
a 10ml roll-on typically lasts 8–10 months with daily wear at the pulse points.
how fast does it ship?
orders placed before 3pm ship the same day; everything else within 24 hours. free shipping over £50, tracked worldwide delivery in 3–7 business days.
is the packaging discreet?
yes. every order ships in discreet packaging with no product name on the outside.
