You didn't define a font, hence the default font Helvetica is used. If you want to use a Bold font, you need to create a Font object for the Paragraph.

For instance:

Font boldFont = FontFactory.GetFont(FontFactory.HELVETICA_BOLD, 12);
Paragraph p = new Paragraph("Text to the left", boldFont);

If you want to make only a couple of words bold, you need to split up the Paragraph in different Chunk objects with different fonts. This is explained on the official web site: How can I use regular and bold in a single String?

This is a simple example (notice that there are different ways to create a Font object):

Font regular = new Font(FontFamily.HELVETICA, 12);
Font bold = Font font = new Font(FontFamily.HELVETICA, 12, Font.BOLD);
Paragraph p = new Paragraph("NAME: ", bold);
p.Add(new Chunk("Pol", regular));
