To tell a rather personal experience. When i was running prop tren mast clen and t3 (show prep). The wife and I were having sex. My left ham cramped so bad it put my heel into my ass. I couldn't move. Im yelling pull it out! pull it out! Meaning my leg. She thought something else. When she finally realized what was happening it took both of her hands holding and pulling my leg to straighten it out. Worst pain ever.
