Hello, I ve been taking testosterone injections for almost year now. 100 CM, once per week. I find that I have extremely low energy before the end of the week rolls around. I also have a weird taste in my mouth, that reminds me of when I was using eye drops to fight conjunctivitis. 2 questions, 1) is once per week enough? 2) Should I cycle off for a while to let my body create its own juice. And if so for how long?
