I don't know about placenta but I have been taking collagen in the past. Raw marine collagen and collagen in a supplemental drink. It does nothing to my breast not even swelling. From what I know (reading testimonials from my local people about collagen) collagen tighten the skin so it will work for those with mature, saggy breasts. so the "succeed" testimonials about enhancing breasts usually come from women who have breastfed and deflated

The collagen drink that I drank is mixed with pueraria lobata. It does plump my butt but not my breast. I don't know why, maybe because everybody is different I just want to share my experience with collagen. That's all.
