Injectable Testosterone

Keeping in mind that the esther is ~35% of the molecule by weight
As @Cataceous already reminded you in another post, no it isn't.

TC has a molecular weight (MW) of 412.605 g/mol. Testosterone has MW of 288.42 g/mol. Hence TC is 69.9% testosterone by weight and 70 mg/week of TC is 49 mg/week of testosterone. ~70.% not 75% to 2 significant figures. Hence, ester is 30%.
 
Okay guy. I get it. 5% corrected. In the grand scheme of what's going on in the steroid world not sure it's a life and death issue.
Great, since you wouldn't want to propagate misinformation to guys/gals trying to learn, right?

And nice red herring and rationalization in your second sentence.

In summary, TC is 70% testosterone by weight.
 
Would love to know before and after testosterone ranges and any blood lab goals you have, although obviously maximum benefits without side effects sounds great.

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.
