If you're a male who's doing everything else, like you're exercising, you're sleeping well, your nutrition is locked in, you are taking creatine and fish oil, you're taking care of your gut microbiome and you want to experiment with shilajit, well, by all means, find a reliable source of shilajit. They are out there. Just look for one that has some testing for authenticity. And then you're likely to be able to see within about a week or so if it leads to a significant increase in vitality, libido, whatever it is that you're seeking.
