The parking lot analogy is somewhat correct, except when a car is in a spot (ie androgen is in receptor) then its working its magic. The receptor clears when the androgen has been"used up" and is ready for another androgen. It doesnt matter if your on cycle or off, the process is the same, its just when on cycle you have a lot more androgen to do its job. Your body has far more parking spots than cars.
Having said all that, when your on a cycle your consuming resources at an accelerated rate yet you are not taking in nutrients (think minerals and vitamins) to match that rate and when you tape out the body so much that it has to prioritize basic function over muscle basic function will always take precedence.
Additionally your gonna have to pay the piper sooner rather than later running a cruise of 250mg.
I would wager 99% of the people on this board are deficient in at least 1 nutrient, have a skewed ratio of various nutrients or have excessive toxicity which creates a false deficiency. So when you cycle your already starting at a disadvantage, its only a matter of time before the body puts on the breaks to focus on the basic bodily functions.
