Copulins originate from the primary female pheromone and are exclusive to women. This pheromone is produced by women during their fertile period.

Copulins can be used by women to signal to men that they are in their fertile phase. Research reveals that men find women particularly attractive during their fertile period due to a special scent emitted by the female body, namely copulins. Women using copulins send a subtle, provocative signal to men. This indicates that men are subconsciously drawn to women they perceive as more likely to bear offspring.

Copulins can also be used by men to increase testosterone levels, boosting confidence, improving mood, and making the wearer more attractive to women compared to others. Studies show that men using copulins create an impression in women that they have a high social status and are closely associated with other women, making them highly desirable to women.

Another study found that men using copulins are more respected and revered by other men, which is why many alpha pheromone products include copulins as a primary component.

Laboratory-Synthesized Human Copulin Formula

Our Lab XS synthesizes a human copulin formula that mimics the secretions of a healthy, fertile vagina. We precisely follow the formula developed by Astrid Jutte and Karl Grammer, used in their now-famous study on the effects of copulins on men at the Ludwig Boltzmann Institute for Urban Ethology in Vienna, Austria, to produce our copulins.

This study measured the increase in testosterone levels in male subjects when directly exposed to synthetic copulins from ovulating women. A total of 106 men were divided into four groups: three groups were asked to inhale synthetic human copulins directly, while the fourth group, the control group, inhaled only water vapor. The three test groups inhaled copulins composed of fatty acid formulas typically found in vaginal fluids of women at various points in their menstrual cycle. Two test groups inhaled copulins from different stages of the menstrual cycle, while the third inhaled copulins from the ovulation period. Testosterone levels in all groups were tested via saliva, with the following results: The control group inhaling water vapor showed a halving of testosterone levels. The two groups inhaling copulins from non-ovulatory menstrual phases showed no change. The group exposed to copulins from the ovulation period showed a doubling of testosterone levels.

We follow the ovulation formula in producing our copulin formula, which we now offer in oil form using DPG.

This product was previously named Desire Me Oil. Desire Me Oil and Desire Me + Spray are now identical in formula to Desire Me +, and the product is now simply called Desire Me without the “+”.
