@Alex, these are not steroids or pure testosterone, these are testosterone boosters with which you can’t expect results in just 2 weeks of using it, your testosterone is getting bigger each day and you couldn’t tell a difference in higher testosterone because it’s climbing slowly so give it a month or two, plus if you’re using these only two times a week no wonder you don’t see changes, it’s designed to be used every day and if you’re heavier than 80kg you should be taking double the dose DAILY.
