hi our own natural testosterone is high in the mornings that's why most healthy men feel great first thing in the mornings so its best that you match that with your injections. have them as early as you can that's probably why you having sleeping problems your boosting at the time of day when they should be low so your awake and know doubt horny? hope this helps you. good luck
do testosterone injections late the in day make it hard to sleep? . i was recently placed on testosterone replacement therapy and am taking/injecting about 750mg of test enanthate every two weeks.
