"Nonlinear Dynamics and Entrainment in a Continuously Forced Pulse-Modulated Model of Testosterone Regulation"

This may be of some interest to some here. This speaks to the idea of hormones working in sync, and may offer some insight into why sticking to a protocol is perhaps more important than controlling for any of the other side variables. It’s not from an endocrinology journal, and it mostly concerned with the dynamics of systems (it’s from engineering). It should be open access, but I can copy paste if that’s the protocol here.
