I'm going to be blunt here, so please don't think that I'm singling anyone out - I just feel that I need to point something out.
A lot of guys "worry" about starting T because they are "already angry people with short tempers" and that T will somehow spiral their anger out of control.
I have to say - get a grip, folks. Being an "angry person" with a "short temper" is an excuse - anger management is something to think about as is any other form of cognitive therapy. Angry people have deep-seeded issues that need addressing - and if you can't get a grip on that aspect of your life, you need to seriously prioritise because transitioning is no walk in the park. You will be confronted in new ways - treated like a man and reacted to like a man. This may mean potentially dangerous situations and yes, you are still expected to behave like a responsible member of society.
If you think that being on T is going to cause you to "tear the house down", then you seriously need to think about bringing this issue up with a psychologist or therapist because that is inexcusable. A great many guys on T, including myself, have anger issues and manage to function just fine because those problems either have already been or are being addressed. If you don't have control of those issues, then you may want to think about delaying starting testosterone until you manage to find a professional who can help you regain control of your emotions.
As someone else said, T isn't going to transform anyone into the Hulk. If being angry is your natural state, then you have a lot of work to do. Find someone who can help you to find where the anger comes from, what triggers it and healthier ways to process things.
