PCT – Post Cycle Therapy: A Comprehensive Guide

Introduction to PCT – Post Cycle Therapy

PCT or Post Cycle Therapy is a process that bodybuilders and athletes follow after a cycle of steroid or prohormone use. The primary purpose of PCT is to help the body or more specifically, the endocrine system, to restore and get back to its normal function after it has been suppressed during the steroid cycle. This article will delve into the importance of PCT, its process, and the supplements used.

The Importance of PCT

Restoration of Natural Hormone Production

One of the main reasons why PCT is crucial is because it aids in the restoration of the body’s natural hormone production. During a steroid or prohormone cycle, the body’s natural production of hormones like testosterone gets suppressed. This can lead to several side effects like fatigue, loss of libido, and depression. PCT helps to kickstart the body’s natural hormone production, thus mitigating these side effects.

Prevention of Muscle Loss

Another significant benefit of PCT is that it helps to prevent muscle loss. When the body’s natural hormone production is suppressed, it can lead to a catabolic state where the body starts breaking down muscle tissue for energy. By restoring the natural hormone production, PCT helps to keep the body in an anabolic state, thus preserving the muscle mass gained during the steroid cycle.

The Process of PCT

The process of PCT varies depending on the type of steroid or prohormone used, the duration of the cycle, and the individual’s physiology. However, a typical PCT process usually starts 2-3 days after the last steroid dose and lasts for about 4-6 weeks. The process involves using various supplements to help restore the body’s natural hormone production.

Supplements Used in PCT

Selective Estrogen Receptor Modulators (SERMs)

SERMs are often used in PCT to block the effects of estrogen, which can become dominant when the body’s natural testosterone production is suppressed. By blocking the effects of estrogen, SERMs help to stimulate the production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn stimulate the production of testosterone. Commonly used SERMs in PCT include Clomid and Nolvadex.

Aromatase Inhibitors (AIs)

AIs are used in PCT to inhibit the conversion of androgens into estrogen. By doing so, they help to prevent the side effects associated with high estrogen levels, such as water retention and gynecomastia. Commonly used AIs in PCT include Arimidex and Letrozole.

Testosterone Boosters

Testosterone boosters are supplements that naturally increase the production of testosterone. They are often used in PCT to help restore the body’s natural testosterone production. Common ingredients in testosterone boosters include D-Aspartic Acid, Fenugreek, and Tribulus Terrestris.


In conclusion, PCT is a crucial process that helps to restore the body’s natural hormone production after a cycle of steroid or prohormone use. By using various supplements, PCT helps to mitigate the side effects associated with hormone suppression, prevent muscle loss, and maintain the gains made during the steroid cycle. However, it’s important to note that PCT should always be done under the guidance of a healthcare professional to ensure safety and effectiveness.
