I would take it in the morning so it comes closer to mimicking your bodies natural t levels which are always higher in the morning and then fall as they day progresses. Whatever time you choose I would try to be consistent which the injection time as much as possible.
Thanks. I was thinking the morning also, but I had an endocrinologist pushing taking hormones at night. When I was on cypionate, I always took my dose in the morning along with HCG.
I believe it's 14 hours.Half life is one thing, but the increase and peak in blood level is another.
Is there a graph anywhere that shows blood level of propionate over time from injection?
I posted one here. I also summed the data of the first subject to show what daily dosing would look like. There's actually not a lot of variation, especially if you disregard the dip at six hours:Half life is one thing, but the increase and peak in blood level is another.

I was expecting an earlier peak, but it's more like 12 hours post-injection.
I do find that injecting before bed hurts sleep quality.

My own data contradict that graph and are more in line with other studies, and in particular work by Nieschlag finding a half-life for propionate of about 19 hours. Importantly, my measurements suggest there is a rapid rise to peak serum testosterone in the first few hours after an injection, which is followed by a steady decline to the next day's pre-injection trough.Might have to swap to AM injections because of this. I was hoping that when I injected before bed it would start to rise and in 4-6 hours and be time I woke up it would be like waking up naturally with highest test levels.

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.
Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.
The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
