The effects of hormones differ widely among people but if you have any specific questions, feel free to ask these too.
PS For general info about hormones for transgender men, you may find the following guide useful. It's called Medical therapy and health maintenance for transgender men: A guide for health care providers. Two of the authors are medical practitioners and, as you can tell from the title, it's a guide for health care providers, so you might find it a bit technical. It can actually be a useful thing to give to your doctor too, if they don't know much about this area. It's downloadable in various forms from here:
