Bill Roberts, i hope you (or somebody else) know that how much, if any, does Osmopherine rise free testosterone levels.
I know nothing about it, even what it is
(osmopherine is not a real name of any substance so far as I know and there are certainly no medical articles using that name). Doing a websearch revealed that some push it as a pheromone to attract women,
and one company claims it increases testosterone. If they have a specific reason for making that claim, then I could go look at that reason. Other than that there’s just nothing to go on so far as I can tell.
