Where does it say that? I read everywhere that it peaks 24-48h. If injecting daily that translates to about 12h. How on earth would it be 1-2h?!

Regarding feeling, if 700 and 1300 feel the same, 700 is healthier (although free T is more relevant) so might be a better protocol to keep between 700 and 900.
