Hydroxyprogesterone caproate is a much more potent progestogen relative to hydroxyprogesterone, but does not have as high of affinity for the progesterone receptor relative to progesterone, though it is more potent than progesterone "in vivo" due to differences in the pharmacokinetics of the two compounds.
