Advice on blood test results?

You’ll get no argument from me. The half-life of Test has to be very short for TRT to work. Jatenzo has a 6 hour half-life, requiring twice daily dosing.

Compared to your 259 ng/dL, mine was 91 and 120 ng/dL.
What do you mean about the half life? Like the type of testosterone?
 
What do you mean about the half life?
Sustanon has multiple half-life esters, which allows for the T to be released into you bloodstream at different times, otherwise you would have to inject T every 30 minutes because it would clear out of your system very quickly.

The multiple esters can cause problems for some men. The single esters like cypionate and enanthate are almost always best and preferred.

Cypionate is the most popular.

Gel is not usually the best option, too many men fail to absorb enough. I tried gels and cream, highest I got was 86 ng/dL, lower than pre-TRT.

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.
