Swolgenix XL Knowing the safety profile of any male enhancement product involves close interrogation of the ingredients of the product, (knowing what elements make it up), and what their effects and side effects are. And while the basic ingredients of a product might be more or less safe, it helps too, to interrogate the mechanism through which the male enhancement product works (is it by raising the male hormone levels, is it obliterating the effects of female hormones in a man's body - and so on), because some mechanisms are known to be safer than others.
