I may be completely misremembering, since my very cursory study of endocrinology was years ago, but AFAIK adrenaline does not "burst" and it does not "rush". Hormones, in general, are not rapid-acting, at least not by the common definition of "rapid".

And yet oxytocin does seem to have that facility -- directly into the literal heart of the vascular system:Studies on rats show that the "heart is a site of oxytocin (OT) synthesis and release."
