Overview

Beta-androstanol (5ฮฑ-androstan-3ฮฒ-ol, CAS 1224-92-6) is a fully saturated androstane steroid โ€” meaning it has no double bonds in the ring system. It is a testosterone metabolite and chemical cousin of androsterone. It was first discovered and introduced as a pheromone in 1998 by the Salk Institute.

It is classified in the social unisexy spectrum โ€” effective for both men and women โ€” and is described as a "chemical hybrid of beta-androstenol and androstanone" by the community, combining social comfort with smooth charm.

Pharmacology

What It Is

Beta-androstanol (Cโ‚โ‚‰Hโ‚ƒโ‚‚O, MW 276.46) is the simplest androstanol โ€” just the androstane skeleton with a single 3ฮฒ-hydroxyl group. No ketones, no double bonds. It is the 3ฮฒ-epimer of alpha-androstanol (which has a 3ฮฑ-OH). The fully saturated structure makes it one of the most chemically stable pheromone molecules.

Biosynthesis

Endogenous steroid produced as a reduction product of androgens:

Testosterone โ†’ DHT โ†’ Androstanedione โ†’ Androstanone โ†’ Beta-Androstanol (via reductases)

Also related to epiandrosterone (which shares the 3ฮฒ-OH orientation but has an additional 17-ketone).

Detection

Detected primarily via VNO at close range. The saturated structure means virtually zero volatility โ€” it does not evaporate or travel through air. Works through skin contact and close proximity VNO pumping.

Per PheromoneXS, beta-androstanol is "indicative of an as yet unclassified neurological influence not directly associated with olfaction" โ€” suggesting the mechanism may extend beyond standard VNO receptor binding. The Salk Institute described it as "the only hormone that stops or reverses gene activity," though the specifics of this gene regulation mechanism are not well characterized.

Do not confuse with:

  • Beta-androstenol (5ฮฑ-androst-16-en-3ฮฒ-ol) โ€” has one double bond at position 16
  • Beta-androstadienol (androsta-5,16-dien-3ฮฒ-ol) โ€” has two double bonds at positions 5,16
  • Epiandrosterone (5ฮฑ-androstan-3ฮฒ-ol-17-one) โ€” same 3ฮฒ-OH but with a C17 ketone

The saturated ring system gives beta-androstanol very low volatility, meaning it is detected primarily through close-range pathways rather than olfactory receptors.
