reasoning: typical test boosters of today rely on weak AIs to manifest its rise of testosterone. You see this in literally every test booster.
After a steroid cycle, your estrogen is artificially high because until you quit using the androgens the body thought it was ridiculously high in test.. So in an effort to normalize the system it pumps out tons of estrogen. (BTW this can happen with non aromatizing steroids too).
Now that your done "supplying" the body with androgens, male hormone levels plummet leaving a massive amount of estrogen in the body (unchecked). Enter a SERM. this will hold off estrogens effects while the body senses a massive drop in estrogen. Now in an attempt to normalize once again, it secretes LH, FSH, ect to raise test as fast as possible.
Its at this time your body will be producing enough aromatizable substrate (test) to cause a rebound of estrogen. this is what you are trying to stop with a test booster assuming you're using OTC ancillaries. Those who use drugs would introduce a regular AI or HCG and forgo the test booster all together.
