Best time of day for injection?

I'm doing EOD injections. I'm just wondering what people think is the best time of day for injection? How long does it take for the test to be absorbed by the body and start giving an effect? If it's very quick, I'm thinking morning would be the best time as I will get the maximum effect during waking hours. If it takes some hours to take effect, I'm thinking night time would be better as it will start having an effect by the time I wake. Or,.. does it really not matter very much?

I have read 24 to 48 hours for peak after T shot. I will vote for it not mattering regarding timing. It takes time for body to cleave off usable T and for T to enter circulation from muscle. I don't notice any difference between morning or night shots.
 
I'd say to pick a time, any time, that you can be consistent with and go with that. Consistency is the biggest factor.
 
I like injecting first thing in the morning. My day gets very busy and a lot of times I'll just crash at night, so I inject every morning.

Understanding Your Hormones

Estradiol (E2)

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.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
