Like other AAS, drostanolone is an agonist of the androgen receptor (AR).  It is not a substrate for 5α-reductase and is a poor substrate for 3α-hydroxysteroid dehydrogenase (3α-HSD), and therefore shows a high ratio of anabolic to androgenic activity.  As a DHT derivative, drostanolone is not a substrate for aromatase and hence cannot be aromatized into estrogenic metabolites .  While no data are available on the progestogenic activity of drostanolone, it is thought to have low or no such activity similarly to other DHT derivatives.  Since the drug is not 17α-alkylated , it is not known to cause hepatotoxicity . 
Androx is famous because it was one of the first anabolic steroid where were a mix of 4 different testosterone esters. This preparation contains: testosterone propionate, testosterone isocaproate, testosterone phenylpropionate and testosterone decanoate. It was created for fast and at the same time long action. It is a strong anabolic steroid with well-expressed androgenic component. The active live of this anabolic is approximately 21 days. Once you started a cycle of 8-12 days of injecting, like one time during 5 days of Androx, it will give effective results. In the first 5 days, already you will notice an increase in your weight training. Bodybuilders are using Androx usually to put on mass and size while increasing the strength. Taking Androx even during the first cycle, it can bring very good results in the first cure, even if the dose isn’t so big. Because of its ability to absorb water, this preparation is not suitable for pre-competition preparation in bodybuilding. At the same time, being very a strong androgen, post course therapy should take place approximately 2 weeks after the last injection of the preparation, because it is active during long time in the blood. If you really need extreme volume, then you may combine Androx with Anadrol or Dianabol. But if you need for a clear relief, it could be combined with Trenbolone Mix or of Androx:· Increase of power rate· Increase of muscle mass· Increase of red blood cell formation· Increase of catabolic processes· Increase sexual desire during the cycle, and decline after its completionSpecification:· Active Life - 21 days· Average Dose - 250-1000 mg/weekly· Aromatization - Yes..
