Frequently Asked Questions
Evidence-based answers to common pheromone questions. Each answer links to a full article with scientific sources.
Science
Do human pheromones actually exist?
Yes, but it's complicated. While mainstream science debates the terminology, compounds like androstadienone have documented effects on mood, cortisol, and brain activity. The debate is largely semantic - whether to call them 'pheromones' or 'chemosignals.'

Genetic variation in the OR7D4 olfactory receptor determines androstenone perception. About 50% of people find it unpleasant (urine-like), 35% neutral, and 15% pleasant. This is determined by your specific OR7D4 gene variant.

The VNO structure exists in most adults, but its functionality is debated. However, pheromone detection may occur through Cranial Nerve Zero (CN0) or the main olfactory system instead. The 'vestigial VNO' argument doesn't disprove human pheromone effects.

Real self-effects exist for certain molecules. Androsterone and related 3ฮฑ-hydroxy steroids are GABA-A receptor modulators - the same mechanism as anti-anxiety medications. The confidence boost is neurochemical, not just psychological.
Read full article โWhat does the science actually say about androstadienone?
Androstadienone (A1) is the most-studied human pheromone candidate. Research shows it affects women's mood, modulates cortisol levels, and activates the hypothalamus. The Wyart et al. (2007) study is the landmark paper.

What's the difference between androstenone, androsterone, and androstenol?
Androstenone creates sexual tension and dominance signals. Androsterone projects authority and respect without aggression. Androstenol creates friendliness and approachability. Most effective formulas combine all three in balanced ratios.

How much pheromone should I apply?
Start with 1-2 drops or sprays. The most common mistake is overdosing - more is NOT better. Signs of overdose include people avoiding you, odd looks, and reduced engagement. If in doubt, use less.
Read full article โWhere should I apply pheromones?
Pulse points (neck, wrists, behind ears) work well for volatile molecules. For non-volatile compounds like androsterone, apply closer to the face (jawline) since they require close proximity for detection via the VNO pumping mechanism.
Read full article โHow long do pheromones last on skin?
Typically 4-8 hours depending on the molecule and carrier. Oil-based carriers (DPG) last longer than alcohol-based. Volatile molecules like androstenone diffuse faster but may not last as long as non-volatile ones like androsterone.
Read full article โWhy do pheromones work better some days than others?
Multiple factors affect results: your natural hormone levels, stress, diet, the specific people you encounter (their receptor genetics), environmental factors, and your own behavior congruence. Pheromones amplify - they don't replace fundamentals.

What's the best pheromone for beginners?
Start with androstenol-focused products like Scent of Eros or products with balanced formulas like Alfa Maschio. Avoid pure androstenone products initially - they're easy to overdose and can create negative reactions.

Can women use pheromones too?
Yes. Women can use estratetraenol, copulins, and certain androstane products. Some women also use small amounts of male pheromones for confidence and authority effects. The science applies to all genders.
