Epiandrosterone [also known as 3β-androsterone, Epi (17-ketosteroid epiandrosterone)] is a naturally occuring/endogenous steroid hormone with weak androgenic activity. It is also a natural/endogenous metabolite of Dehydroepiandrosterone (DHEA). EPI formed in peripheral tissues is a metabolite of testosterone precursor DHEA. After circulation in vivo, EPI is ultimately excreted from urine. Serving as a weak androgen, EPI is proved to block the pentose phosphate pathway and to down-regulate intracellular NADPH levels.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
