What Is Estratetraenol?
Estratetraenol, often abbreviated EST, is an estrogen-related steroid discussed as a putative human chemosignal. Aroma Fero sells an individual-molecule unscented concentrate labeled EST-NOL rather than a completed multi-ingredient cologne. Proposed effects on emotions and social perception are scientifically unsettled.
Formula Transparency and CAS
The seller identifies estratetraenol as estra-1,3,5(10),16-tetraen-3-ol, CAS 1150-90-9, with minimum stated purity 98%. Its ingredient description references dipropylene glycol, perfumer’s alcohol and isopropyl myristate, while the summary gives MCT oil or perfumer’s alcohol. Because the carrier descriptions differ, confirm the variant’s actual composition.
Concentration Options and the Math
The broad listing describes 10–40 mg of ingredient per 10 mL bottle, with detailed options explicitly describing 10 and 20 mg oil/alcohol plus a 30 mg alcohol selection. A nominal 10 mg/10 mL mixture is 1 mg/mL; 20 mg/10 mL is 2 mg/mL. These are seller-reported concentrations, not validated application doses or proof that a drop has a fixed volume.
What Do the Advertised Effects Mean?
The product description repeats pheromone-community claims about comfort, improved mood, reduced social anxiety and enhanced attraction. Those are anecdotes and interpretations, not proven effects of the current cosmetic. Some published experiments have studied putative chemosignals under controlled settings, but findings do not justify forecasting individual responses to a retail bottle.
Estratetraenol Versus Androstadienone
Our androstadienone research overview covers another putative human chemosignal. Estratetraenol is chemically different and sometimes discussed alongside androstadienone in experimental work. No defensible rule follows that one creates happiness while the other creates romance in the real world.
Carrier Choice and Practical Differences
An alcohol preparation may evaporate differently from an oil-based additive, but the exact carrier declaration and product stability should be checked. Unscented does not promise no perceivable base odor. We have not smelled or evaluated the formula, and mixing additional concentrates is not a proven way to enhance interpersonal effects.
Retail Pricing and Variant Availability
The £29.95–£59.95 advertised range covers multiple selections. Some higher-strength concentrations list additional production days. The general product page shows a cart control, but that is not proof every desired combination is in stock. Check shipping, selected concentration and the refund rules at checkout.
Scientific Evidence and Interpretation
Human odor communication research is a legitimate subject, but no independent, replicated finished-product trial establishes this 10 mL estratetraenol concentrate as a reliable mood, dating or trust intervention. A claimed chemical purity is useful for identification, not a behavioral efficacy outcome.
Pros, Cons and Final Verdict
Pros: Disclosed molecule/CAS, 10 mL format, claimed purity, carrier and concentration variants. Cons: Inconsistent carrier text, incomplete variant availability, no verified batch assay and no demonstrated effect on other people’s emotions. Verdict: A specialized ingredient product that should be evaluated on accurate specification rather than pheromone folklore.
