Description

Androsterone, or 5α-androstan-3α-ol-17-one, is an endogenous steroid hormone, neurosteroid, and putative pheromone.It is a weak androgen with a potency that is approximately 1/7th that of testosterone.Androsterone is a metabolite of testosterone and dihydrotestosterone (DHT). In addition, it can be converted back into DHT via 3α-hydroxysteroid dehydrogenase and 17β-hydroxysteroid dehydrogenase, bypassing conventional intermediates such as androstenedione and testosterone, and as such, can be considered to be a metabolic intermediate in its own right.Androsterone is also known to be an inhibitory androstane neurosteroid,acting as a positive allosteric modulator of the GABAA receptor,and possesses anticonvulsant effects.The unnatural enantiomer of androsterone is more potent as a positive allosteric modulator of GABAA receptors and as an anticonvulsant than the natural form.Androsterones 3β-isomer is epiandrosterone, and its 5β-epimer is etiocholanolone. The 3β,5β-isomer is epietiocholanolone.

Applications

Androsterone is one of the androgens, which are steroid hormones that affect the masculinization of the fetus and child and that maintain or create masculine traits in adults. Testosterone is the most active and abundant of the androgens. Androsterone was originally isolated from male urine in very small amounts.
A molecule of androsterone is very similar to testosteron. It consists of three six-member carbon rings and one five member ring joined along common sides. It has a beta-isomer called epiandrosterone, in which an hydroxyl group occupies a different geometric position. The ratio of androsterone to epiandrosterone is thought to be important in how masculine behavior is interpreted by others
Pheromones are well known in insect behavior. Their role in insect mating, navigation and nest protection has been studied, and active compounds have been isolated. Pheromones are the basis of some insect baits.

Dosage

Study delivered a dose of 50 mg of 1-DHEA for 10 months with no serious adverse events reported.
1-DHEA was administered at a dose of 200 mg/day for 24 weeks with slight androgenic effects noted.

Another study utilized a dose up to 400 mg/day for 8 weeks with few adverse events reported.A longer term study followed patients dosed with 50 mg of 1-DHEA for 12 months with the number and severity of side effects reported to be small
