PCT generally lasts between 2-6 weeks. The most important part that you need to remember about PCT is what the goal of taking PCT is: to balance your hormones in your body and stabilize whatever it is that you messed up. Because of this, PCT can sometimes vary in the exact duration that it ends up being, but most courses of PCT fall between that timeframe.
You should never try to end PCT early or seek to find a way to try and get it to finish faster. Your health is more important than anything and that’s the entire point in taking PCT in the first place: to make sure that your health stays stable while you’re doing SARMs, which are potent supplements which can damage your body and hormone system if not used carefully.
