Modeling Growth Hormone Pulsatility

Dear everyone, I am looking for any reference for modeling hormone pulsatility in PK softwares. Would you recommend some good articles to me? Or any suggestion? Thanks in advance. I searched PubMed, and the Pulsatility can be modeled by some statistical models, which is not that easily to translate and implement in PK software, such as NONMEM, or ADAPT II.
