Prohormones That Don't Convert to Estrogen | Full Breakdown

One of the top questions we get at My Supplement Store is: "Which prohormones won't cause estrogen issues?" Estrogen is important for both men and women, but when levels climb too high during a cycle, it can bring on side effects like bloating and mood swings. In this post, we'll walk through what aromatization is, why it matters, and highlight prohormones that don't convert to estrogen.

What Is Aromatization?

Aromatization is simply the process where your body converts testosterone into estrogen using an enzyme called aromatase. While estrogen plays a role in your health, too much can cause issues. Especially if you're running certain compounds that spike testosterone.

Side Effects of High Estrogen

If estrogen gets too high during a cycle, you may notice:

  • Water retention (the most common sign)
  • Puffiness or bloating
  • Low energy or feeling sluggish
  • Breakouts or acne
  • Mood swings or irritability

These side effects are your body's way of telling you that estrogen might be climbing higher than it should.

How to Manage Estrogen on Cycle

The good news is, there are products designed to block or minimize estrogen conversion. Some of the most effective options include:

These can help keep estrogen levels in check so you can stay comfortable and focused on your results.
