It seems like some users don’t buy into the notion that low shbg is cause to inject more often.
But the math is relatively simple:
take two men: Man A has a FT percentage of 2% and Man B has a FT percentage of 3%. If both take 100mg of T a week, and each has a TT peak of 1000 and trough of 500...

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.
