This alternate definition is more useful, however, since you can use it to relate lengths of arcs to angles. The length of an arc is is the radius r times the angle Î¸ where the angle is measured in radians. For instance, an arc of Î¸ = 0.3 radians in a circle of radius r = 4 has length 0.3 times 4, that is, 1.2.
About 17 percent of men treated for low T receive testosterone injections every 7 to 22 days. Testosterone levels peak two to three days after the injection and then slowly drop until the next dose of the hormone is given. There are also testosterone patches that men can use.
