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 . 
In one small scale clinical trial of depressed patients, an improvement of symptoms which included anxiety, lack of drive and desire was observed.  In patients with dysthymia , unipolar , and bipolar depression significant improvement was observed.  In this series of studies, mesterolone lead to a significant decrease in luteinizing hormone and testosterone levels.  In another study, 100 mg mesterolone cipionate was administered twice monthly.  With regards to plasma testosterone levels, there was no difference between the treated versus untreated group, and baseline luteinizing hormone levels were minimally affected. 
Q. I have met my close friend after 3 years. She is showing some signs of high depression. How can I help her? I have met my very close friend after 3 years and she is very depressed. I am worried that she is showing some signs of high depression. She talks all rubbish and negatives these days which is filled with that nonsense hopelessness. She was fine and going good when I left her and now she is completely negative in her behavior and also very depressed. She is not able to enjoy my company. She had lost her weight and her eyes reflect the bluntness. She keeps silent most of the time. How can I help her? A. I think first you must talk to her and find out about when and how this started. Take her to all the places where you both used to go. She might have come across difficult phase in these years which would have made her depressed and she may need a support to bring her back to normal way of living. We cannot say that this is a depression which would get cured by just talking and knowing the reasons but you must help her to fight back for the thing she had lost. If there is no desired result, then do consult a physician.
