Is 1-Andro a Prohormone?

Yes — 1-Andro Is a Prohormone

1-Andro (also known as 1-DHEA or 1-Androsterone) is considered a prohormone.
That means it’s a precursor compound that can convert inside the body into an active anabolic hormone called 1-Testosterone.

This conversion may support:

• Lean muscle growth

• Strength increases

• Harder, “dry” muscle look (less water retention)

Because it’s a non-aromatizing compound, it’s less likely to convert into estrogen than many older prohormones.

What Is 1-Andro Made From?

1-Andro is derived from DHEA (dehydroepiandrosterone) — a hormone your body naturally produces in small amounts.
The version used in supplements is a synthetic form, designed to increase conversion to 1-Testosterone once processed by the body.

In short:

1-Andro = a modified form of DHEA that your body can turn into an anabolic hormone.

Is It Safe?

Scientific data is still limited.
Research on similar andro-based prohormones found possible side effects such as:

• Reduced natural testosterone after a cycle

• Changes in cholesterol levels

• Elevated liver enzymes

That’s why users typically follow a cycle (4–8 weeks) and then use post-cycle therapy (PCT) to help natural hormone recovery.
Always consult a healthcare professional before using any hormonal product.

Is 1-Andro Legal?

In the United States, 1-Andro is a regulated compound under the Anabolic Steroid Control Act.
Some versions are still sold legally as dietary supplements, but sports organizations like WADA classify it as a banned anabolic agent.

If you compete in tested athletics, avoid using 1-Andro — it can trigger a positive doping test.

Bottom Line

✅ Yes, 1-Andro is a prohormone — a DHEA derivative that can convert to 1-Testosterone.
⚠️ However, human research is limited, and side effects are possible.

It’s not a mild “test booster” — it’s a serious anabolic compound that should be used responsibly, with proper support and recovery.
