What hormone are you talking about? Insulin and testosterone will be probably transported differently...

what about Growth Hormone...?

Transported from where to where, exactly? If you mean from the gland to the target tissue, then it is the circulatory system which transports hormones around the body.

If you mean from the inside of the cells in which they are produced, then it would be diffusion through the membrane for steroid hormones and transport vesicles and exocytosis for peptide hormones. Growth hormone is a peptide hormone.

Not to sound like a complete jerk, but this information isn't in the Endocrine System chapter of your textbook?

growth hormones are transported inside the cell?

EDIT
wiki says:

GH acts by interacting with a specific receptor on the surface of cells.

Growth Hormone is produced inside the cells of the anterior pituitary gland and then transported by transport vesicles to the membrane and out of the cells by exocytosis.

I was not referring to the function of hormones when they reach their target tissues because the original post was asking about at the gland. This was the operative phrase in my post:

from the inside of the cells in which they are produced

OK...., its very helpful., thanks
