How it works
It binds androgen receptors and, unusually, also eye receptors that affect how the eye adjusts to light.
Clinical reference dose
Clinical reference: there is no human trial dose. S4 was only studied in animals.
Yellow-tinted vision and poor night vision are commonly reported.
These are reference amounts from labels and clinical studies, not a personal recommendation. A doctor sets the right dose for you, using your bloodwork.
