I don’t know what the hell a “chirurgical” is, but there’s plenty of things that work perfectly well without 100% scientific documentation. Allow me to demonstrate.
Scientists don’t fully understand exactly how a transistor works, on a very low level, nor superconductors amongst other phenomena and technological building blocks. There are ideas as to how they might work, in theory.
Thing is, the theories are usually based on results, not the other way around. We do our best to explain the things we see happening around us, hence religion. (but that’s another topic entirely) Point is, we don’t need an explanation to know something works, somehow.
You don’t need to know [b]exactly[b] the biological mechanism behind enlargement to understand that there are thousands of guys here who have reported significant gains in both length and girth. Whatever they’re doing, it makes sense that the penis is larger for it, whether there are more cells or simply larger cells is relatively inconsiquential, given that virtually nobody has ever reported negative health concerns beyond temporary injury (and all of those were for a reason)
Hence, your computer is sitting there working as it was designed, is it not? I don’t give a fuck how it works on such a low level, just like I don’t care how my dick is getting bigger, only that it is!
