after going the transdermal route, the dr has finally put me on test cyp injections. I gave myself the first injection sat morning. used a 25g needle and injected the 150mg dose (approx .73ml) into top thigh muscle. sterilized vial top, drew, looked for air bubbles, pushed out til test came out needle, sterilized skin, inserted, checked for blood, injected (slowly) no problems.
everything was fine til sat night. injection site does not hurt, but let is sore 4" below site into knee. outside of knee is a little red and warm.
