Prohormones: What They Are and Why People Use Them

Let’s keep it simple.

Prohormones are like building blocks. On their own, they don’t do much. But once inside the body, they convert into active hormones—mainly anabolic ones like testosterone. This makes them popular among people who want to build muscle, gain strength, or get leaner faster than they would through diet and training alone.

Now, that doesn’t mean they’re magic pills. Far from it.

Prohormones sit somewhere between supplements and steroids. They’re not quite as intense as anabolic steroids, but they still come with noticeable effects—and responsibilities.

Let’s break it down.

So, what exactly are prohormones?

Think of prohormones as “hormone precursors.” Your body takes them, converts them through enzymes, and produces an anabolic hormone in return. Once converted, that hormone starts influencing your body—things like:

Protein synthesis
Muscle recovery
Libido
Fat storage
Mood and energy

Most people use prohormones to get bigger, stronger, or leaner—sometimes all three. But unlike protein shakes or creatine, prohormones alter hormone levels, which means they need to be used with more caution.

How do prohormones work?

Imagine your body is a construction site.

Your diet gives you the bricks and mortar (nutrients). Your workouts are the blueprint. But hormones? They’re the construction crew—fast, efficient, and capable of turning effort into visible results.

Prohormones are like sending in backup for the crew. More workers = faster progress.

Here’s a basic look at how it goes:

You take a prohormone orally.
Your liver metabolizes it into a target hormone (like testosterone or something stronger).
The converted hormone enters your bloodstream.
It binds to receptors in muscle tissue, boosting anabolic activity.

Result? You grow. You recover faster. You may even lose fat, depending on which compound you’re using.

Popular types of prohormones

Not all prohormones are the same. Some are geared for bulking, others for cutting, and some for recomping (gaining muscle while losing fat). Here’s a short list of common types:

1-Andro – Great for lean muscle gains. Low water retention.
4-Andro – Converts to testosterone. Good for strength and mass.
Epiandrosterone (Epi-Andro) – Known for dry gains and enhanced vascularity.
19-Nor-DHEA – Converts to nandrolone. Better for joint support and bulk.

Each has its own strength and side effect profile. That’s why it’s important to research each one before using it.

What results can you expect?

This depends on the product, your training, and your diet. But here’s what many users report:

3–8 kg of lean muscle in 4–8 weeks
Better strength in major lifts
Faster post-workout recovery
Visible changes in body composition

Of course, not everyone reacts the same way. Some gain more. Some less. It’s not just about the compound—it’s also about how you eat, train, sleep, and recover.

Do prohormones have side effects?

Short answer: yes. Just like anything that affects your hormones, prohormones come with risks. Common side effects may include:

Acne
Hair thinning
Mood swings
Suppressed natural testosterone
Liver strain (especially with oral prohormones)

That’s why on-cycle support and post-cycle therapy (PCT) are essential.

Think of it like this: if you’re going to mess with the system, you need to help it bounce back afterward.

What’s the deal with PCT?

PCT (Post Cycle Therapy) helps your body return to its normal hormone levels after a cycle. Without it, your testosterone could crash—and that means losing your gains, feeling tired, and possibly gaining fat.

Most cycles are followed by 4 weeks of PCT, using products designed to:

Boost natural testosterone
Control estrogen
Support mood and libido
Maintain muscle mass

Skipping PCT is like jumping out of a plane without a parachute. You might land okay—but do you really want to take that risk?

Is it legal to buy prohormones?

This depends on your country.

In the U.S., many prohormones were banned in 2014 under the Designer Anabolic Steroid Control Act. That doesn’t mean they disappeared. Companies found ways to create legal alternatives that still convert into active hormones but fall outside current regulations.

In Europe, including Slovakia, regulations vary by compound. That’s why many people turn to trusted online retailers that specialize in hard-to-find performance enhancers.

Final thoughts

Prohormones aren’t for everyone.

They’re not beginner supplements, and they’re not a shortcut if you’re skipping the gym. But for experienced users with solid training and diet habits, they can offer real results in a short time—when used responsibly.

If you’re considering a cycle, take time to research, prepare your body, and plan your recovery. That’s the difference between making gains… and making mistakes.

FAQs About Prohormones

What’s the difference between prohormones and steroids?
Prohormones are converted by the body into anabolic hormones. Steroids are already active hormones. Steroids tend to be stronger—and come with more side effects—but both affect hormone levels.

Do I need a PCT after a prohormone cycle?
Yes. Even though prohormones aren’t as suppressive as steroids, they still affect your body’s hormone production. A proper PCT helps restore balance and keeps your gains.

How long should a prohormone cycle last?
Most cycles last between 4 to 8 weeks, depending on the compound. Going longer increases the risk of side effects and suppression.

Can beginners use prohormones?
It’s not recommended. Beginners should focus on training, diet, and basic supplements first. Prohormones are better suited for advanced users who have hit a plateau.

Are prohormones liver toxic?
Some oral prohormones can stress the liver. That’s why on-cycle support is essential. Look for supplements that support liver health while on cycle.

Will I lose my gains after the cycle?
Not if you do it right. Proper training, diet, and a solid PCT will help you keep most of your results.!
