Can bulking cause the need for a higher dose?

I inject 100mg once a week and it usually has my peak around 1200 trough around 750. Recently started a lean bulk and a month later my trough is now at 550 all LCMS. SHBG is the same in the low 20s. Could the calorie or weight increase be the cause?

I don’t know why, occasionally our trough is higher or lower. It’s happened to me, I inject the same amount of testosterone and hCG, but my levels are different. Could it be that the testosterone is weaker, or the Labs or a little bit Off?

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.
