Welcome to InsulinReview, where we dive into the science and application of various medications and supplements. In this article, we’ll explore the use of Tamoxifen in bodybuilding. While Tamoxifen is primarily known for its role in treating breast cancer, it has found a niche in the bodybuilding community. Let’s unpack the reasons behind its popularity, proper dosages, and potential side effects.

Understanding Tamoxifen in Bodybuilding

Tamoxifen, often known by its brand name Nolvadex, is a Selective Estrogen Receptor Modulator (SERM). In the bodybuilding world, it’s primarily used to counteract the estrogenic side effects of anabolic steroids. When bodybuilders use steroids, their bodies may convert excess testosterone into estrogen, leading to unwanted effects like gynecomastia (development of breast tissue in men). This is where Tamoxifen comes into play.

Tamoxifen Dosage for Bodybuilding

The appropriate tamoxifen dosage for bodybuilding varies depending on the individual’s needs and the specific cycle they are on. Here are some common guidelines:

When to Take Tamoxifen in Bodybuilding

When to take tamoxifen bodybuilding largely depends on the individual’s steroid cycle. It’s usually started during PCT, which begins after the steroid cycle ends. The duration can range from 4 to 6 weeks, but it’s crucial to follow a tailored plan based on your specific regimen and health status.

Tamoxifen and Weight Loss

There’s interest in the potential tamoxifen weight loss bodybuilding effects. While Tamoxifen itself isn’t a weight loss drug, by managing estrogen levels and reducing water retention, it can contribute to a leaner physique, which is often a goal in bodybuilding.

Tamoxifen for Gynecomastia (Gyno)

One of the primary uses of tamoxifen for gyno on cycle is to prevent or treat gynecomastia. Tamoxifen dosage for gyno typically involves higher doses initially (20-40 mg per day) until symptoms subside, then tapering down.

Tamoxifen PCT (Post-Cycle Therapy)

Tamoxifen PCT dosage is critical for restoring natural testosterone production after a steroid cycle. A common tamoxifen dose pct starts at 20-40 mg per day for the first few weeks, then gradually decreases.

Tamoxifen Cycle and Side Effects

When considering a tamoxifen cycle, it’s essential to understand the potential side effects. These can include:

However, when used correctly, many bodybuilders find that the benefits outweigh the risks.

Is Tamoxifen a Steroid?

A common question is tamoxifen a steroid? No, it is not. Tamoxifen is a SERM, which works by blocking estrogen receptors.


Tamoxifen plays a significant role in the bodybuilding community for its ability to manage estrogenic side effects and aid in post-cycle recovery. However, its use should be carefully managed and ideally supervised by a healthcare professional to mitigate risks and maximize benefits.
