If I take my testosterone at 6 a.m., I don't feel it until 10 p.m. Not a now and then thing; it's consistent. Rare nocturnal erections and no morning wood. I've tried different injection times, such as noon, 3 p.m., 6 p.m., 8 p.m. I suspect this is tied into bipolar illness and misaligned circadian rhythms. Currently 34 mg, IM, EOD, Test E. Perplexing and frustrating.
