Male Hormonal Chin Acne

I have been suffering with acne on my chin and near and around mouth for 2 years now.  I am a 29 year old male.  I really do not get acne anywhere else besides my chin and near bottom lip.  I get acne on the lip and cystic acne on corners of chin.  I have tried BP products, minocyclin, retin A, and other supplements.  My chin acne always stays persistant and is always very red and rashy around the acne pustules/nodules.  At the moment both corners of my mouth have acne sores and another red acne lesion near bottom lip, makes me look like i have herpes and i can not stand it!  So embarrasing.  I have always been told this is probably hormonal acne and for a male what can i do to treat that.  I have not seen an actual derm yet and i really do not want to resort to accutane.  Is there blood test i can do to find out what hormones are out of whack causing perhaps my acne all over chin?  My skin does get oily throughout the day, especially my hair.  I really really want to find the reason behind why my chin is always a mess, it has made me very depressed about myself and i can not live life the way i want because of it.  PLEASE HELP!!!!
