Epiandrosterone is a dehydroepiandrosterone metabolite and a precursor of testosterone and estradiol with hypolipidemic and anabolic property. Epiandrosterone, a potential neurosteroid, appears to bind to the gamma-aminobutyric acid (GABA)/benzodiazepine-receptor complex (GABA-RC), acting as a negative non-competitive modulator of GABA-RC as well as signal through the N-methyl-D-aspartate receptor. In addition this agent inhibits the pentose phosphate pathway (PPP) thereby dilating blood vessels pre-contracted by partial depolarization.

Application: For R&D Purpose.

Shipping & Storage Information

Storage: -20°C
Shipping: Room Temperature (may vary elsewhere)
Stability (shelf life): ≥ 3 years
Origin: PRC

The suggested storage temperature is at -20℃, but the package is usually shipped at room temperature.
1. By “the suggested storage temperature is at -20℃”, it means need to keep the left compound at -20℃ after the package was opened and the API could not be used for a prolonged period of time.
2. Most of our APIs are in dry powder and have very good stability, so it is safe during the transition at room temperature and it could last for 1-2 weeks and even more.
3. For some specific sensitive compounds, we will ship them with dry ice or blue ice bags.
