type A & AB have higher levels of cortisol, and generally, cortisol (if not used properly)  will hurt breast growth, in other words, Type O blood produces less cortisol (less of an obstacle for breast growth). Putting high stress (which sends cortisol super sonic in the wrong direction) to work for us means exercise...and I mean HIIT (high intensity interval training). The repair peptides unleashed by HIIT are (sic) unbleivable, and supplementing NBE/Hrt post workout (with growth promoting proteins)....e.g. whey protein or casein, plus NBE herbs or HRT takes breast growth to the next level. i prefer casein + glycine.+ collagen w/vitamin D, L-tyrosine, glutamine plus E2/MSM and Spiro.


I am ectomorph body type with AB+ blood type. Would HIIT and cardio not be counterproductive then? If I understand correctly, by exercising I can raise my naturally high cortisol level and send it in the wrong direction, but at the same time reduce my scarce fat resources even more. Having some weight would certainly add value to my goals of breast growth & fat redistribution.

I am screwed, and not in a good way either - haha
