Some test booster recipes include AI's, and I'm guessing its not so much to prevent too much estrogen from natural boosters, but more for one of the following 2 reasons:
1. Because test boosters are often used post roid cycle, when an AI is likely needed.
2. Because it is another possible way to increase natural test (by reducing the amount aromatized).
try taking something, with "d-aspartic acid, and calcium" in the ingredients. Test levels are always high on d-aspartic w/ calcium. love it! also, really great for cuts, and strength.
never knew this, thanks. i thought i noticed something different, because ive been taking unleashed for a few weeks and just started a little letro. 1.25 mg and i already noticed a change in libido getting lower, as if it was alot stronger this time
