It's not too surprising. Just changing the injection frequency from weekly to twice weekly can knock down peak serum testosterone by up to 20% or so. When your body is used to higher levels it takes time to adapt to the reduction. It's not fun, but it's worthwhile in the long run. Same with dose reductions, but you can spread those out over a longer period to minimize the discomfort.The tank in mood is hitting me hard, feels like withdrawal, almost like coming off T entirely. Tomorrow will be the start of the third week. Is this normal even when I have not dropped the dose, just changed the frequency?
