I imagine you're using the term "pharmaceutical company" loosely.
breast-wise, yes, it is possible to achieve some enlargement of the breast with pills - as with that "Bloussant" product - but it's not done in a particularly healthy way. it basically inflames the breast tissue, and it swells. this swelling will stop when the product is stopped; breast growth is not permanent, and it's not achieved in a healthy manner.
as for penises, someone can correct me if I'm wrong here, but there is no way to enlarge a penis without surgery, and surgery itself is very tricky; often there will be some degree of function loss.
does this help?
