Will Andractim Cream Help To Increase Facial And Arm Pit Hair?

i am an 18 year old asian guy and i have very little armpit and thin facial hair. my dad has got beard and my older brother which is 20 and he has had his armpit hair since he was 15. i have developed my pubic hair though since i was 14. this is my problem, it is pretty embarrassing and i've been looking for a solution and they said i should get the DiHydrotestosterone cream named Androstanolone and is available in brand name Andractim. i really don't know what to do. please help
