Factors Affecting Protocol Change

Has anyone here had to change their drug dosages (i.e. Test, hCG, AI) when they started hitting the gym and losing body fat/gaining muscle?
 
In theory the leaner you become the less T you should need but we are HPTA suppressed, no? Though I am becoming leaner I have required a higher dose of T as time passes and this has elevated my e2. There are so many variables that influence our hormones I think it would be almost impossible to conclude w/ certainty that bf change alone engendered a need for more/less T. I seem to remember one or two rat studies that demonstrate that obese mice require more T but in humans.....Interesting question

That's interesting Rob that you would need more T as you got leaner. I would expect at the very least one would need less AI when body fat was reduced. I have lost a decent amount of body fat over the last two months, so I'm interested to see if this will affect my blood work in a couple of weeks.
 
I'm guessing I need more b/c my doc is reluctant to prescribe hcg and I'm definitely suppressed at this time. I also have severe sleep apnea and diabetes = too many variables. I will note, and this of course is anecdotal, but my A1c seems to affect the amount of T I need more than my weight/ bf %. (my weight shifting about 20 lbs and my lifts increasing about 25-30% has had less AND if my sleep is off everything is 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.
