Based on the information provided, there is no direct evidence or data presented that indicates a change in stamina after taking Lipitor. Lipitor, also known as atorvastatin, is a prescription medication used to treat high cholesterol levels [1]. Its primary mechanism of action is to lower the levels of low-density lipoprotein (LDL), or "bad" cholesterol, and triglycerides in the blood, while increasing the levels of high-density lipoprotein (HDL), or "good" cholesterol [1].

Although Lipitor may have various effects on the body, such as reducing the risk of stroke and heart attack [1], there is no explicit mention of changes in stamina related to this medication. It is essential to consult with a healthcare professional or pharmacist for personalized information and potential side effects of any medication, including Lipitor.
