Something you should discuss with your Endo. If your blood test was shortly before your injection and you still had very high levels, you need to consider a reduction in your dosage. Excessive testosterone will convert to estrogen and bring with it all of the things your are trying to escape from. If the blood test was just after an injection, high levels are to be expected and will taper down to more reasonable levels before your next injection.
I am on estrogen pills and the time of the blood draw is very critical because Estradiol only has a half life of two to three hours so over a day, levels could range between 1000 and less than 100. Injections use an oil that slowly delivers the medication however while the half life is about 6 days, there is a half life to consider when testing.
