CAS NO.: 897-06-3

Assay: 99% 

Molecular Formula:C19H24O2 

Molecular Weight:284.39 

Packing:5kg/tin

Appearance: Nearly white crystalline powder, soluble in alcohol, insoluble

Usage: Simplified hormonal drugs, from the testis or urine extracted with the role of a male hormone steroids, norethisterone, testis

Application:

 Take one serving (2 caps) per day preferably with a meal; you can take this serving at anytime during the day however before a workout or before bed are the PRIME testosterone boosting time frames. Take for a maximum of eight weeks, then stop for at least 2-3 weeks.The 4-Andro is still fairly unproven when it comes to reliable results, at least that's what my research indicates. 

The 3,5,7-trihydroxy-4-methoxyflavon is supposed to have some anti-aromatase effect, unproven in humans however. Same goes for it's supposed cholesterol leveling properties. 

Several precursors of testosterone and nandrolone introduced on the nutritional supplement market as performance enhancing drugs are banned in sports. Until now they are legally sold without a prescription in the US. Results of excretion studies with related compounds including 7-keto-DHEA and 1-androstenediol are presented. The main metabolites of 7-keto-DHEA are 7-hydroxylated compounds. The commercial 1-androstenediol preparation was contaminated with several other anabolic steroids. Oxidation of 1-androstenediol to 1-androstenedione seems to be the major renal metabolic pathway. Additionally contaminated nutritional supplements containing banned substances not indicated on the label were administered. The results of the excretion studies indicate that after the intake of amounts substantially lower than the recommended dose athletes can fail a doping test for periods up to 120 h.

DHB is supposed to incite the grapefruit effect, that being more ready absorption of supplements, etc.
