SallyHere’s a link to buy the Cortisol replacement therapy booklet. It is on the pens (pediatric endo nursing society) website www.pens.org. Here’s the link http://www.pens.org/educationmaterial.html. I hope it works. If not then go to the pens website and click on resources and then on educational materials. It is only like $8.00 and well worth the money.
