PCT = Pretty Cute Teen girl. They help decca dick when on deca. Just make sure they are cute. Use at a ratio of 1:50 (you are the 1 in this ratio). Belive me, this PTC works wonders.
Or on Sust or test, PCT = Pork, Chicken, Turkey. These white meats help build mass while reducing fat. Introduce your PCT at 80% after the 16th hour after the 3rd injection on a full moon (if 250, then the 4th injection, and 85.5%) or 64% on a quarter moon. Do not PCT on a moonless cycle. But only do so at the rate of 1:10 per liter of blood in your body, so the PCT is not too strong for the Sust, thus defeating the purpose. I personaly wouldn't do more than a 1:15 ratio, but that's just me.
