Does Testosterone concentration matter?

Hypothetically speaking I am injecting 70 mg of testosterone cypionate 100 mg/mL every 4 days. So that’s 7/10 of 1 mL syringe. Now let’s say you’re injecting 70 mg of testosterone cypionate 200 mg/mL which would be 3.5/10 of 1 ml syringe. Would the higher concentration of the 200mg/ml hit your system faster? Since the 70 mg is only suspended in half the oil?
 
Not really because the testosterone is still attached to the Cypionate ester, that must be cleaved off regardless of the concentration . I think one advantage to the 200 mg/ml is less oil to inject. Just my opinion though.

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.
