How Prohormones Affect Testosterone Levels

Who Should Read This Article

This article is for bodybuilders, athletes, or anyone thinking about using hormone supplements to grow muscle or get stronger. It’s also helpful for people who want to know the differences between prohormones and steroids, and who want to understand the possible benefits and risks of using these substances.

Key Takeaways:

• Prohormones help the body produce hormones that build muscle, but they have complicated effects on testosterone levels.
• Prohormones can boost testosterone for a short time but might lower natural testosterone production later on.
• You need to do Post-Cycle Therapy (PCT) to help restore your body’s hormone levels after using prohormones.
• Prohormones can cause serious health issues like liver damage, heart problems, and hormone imbalances if not used correctly.
• It’s important to know about safer options and to talk to a healthcare provider if you are considering using prohormones.

What Are Prohormones?

Definition

Prohormones are substances that your body turns into hormones. They are different from steroids because steroids are synthetic hormones, while prohormones rely on your body to change them into hormones. Prohormones aren’t as strong as steroids but still come with risks.

Origins of Prohormones

Prohormones became popular in the 1990s as a legal way for people to boost testosterone without using illegal steroids. But after a while, studies showed that they could be harmful, and many of them were later banned by the government.

Chemical Structure

Prohormones have a chemical structure that allows them to be turned into androgenic hormones, like testosterone. This transformation usually happens in the liver, and how easily they convert depends on their structure.

How They Work

Prohormones get turned into hormones in your body. Once they enter your bloodstream, enzymes change them into active hormones that help with building muscle. This effect can help increase muscle mass, strength, and athletic performance.

Enzymatic Conversion

Enzymes like 3β-HSD are key in converting prohormones into active hormones. This conversion helps produce muscle growth, improved recovery, and greater overall strength.

Comparison to Steroids

Unlike steroids, which directly give your body hormones, prohormones need enzymes to become active. Because of this, prohormones are often less powerful than steroids but can still lead to some of the same side effects. Also, since they need to be processed by the liver, they can cause liver strain.

Popular Prohormones

• Androstenedione: One of the first popular prohormones, also known as “andro.”
• DHEA (Dehydroepiandrosterone): A mild prohormone naturally produced by the body.
• 1-Andro: Known for its strong muscle-building effects.
• 4-DHEA: Converts to testosterone but also has some estrogenic effects.

Delivery Methods

• Oral Tablets: Common but can stress the liver.
• Capsules: Easier to take and control dosage.
• Transdermal Gels: Absorbed through the skin, which reduces liver strain and increases effectiveness.

The Role of Testosterone in the Body

Testosterone Functions

Testosterone is a very important hormone for many different processes in the body:

Muscle Growth

Testosterone helps build muscle by increasing protein synthesis in the muscles. This makes it very important for anyone who wants to gain muscle and improve strength.

Sexual Health

Testosterone affects libido (sex drive), sexual performance, and overall reproductive health. If testosterone is too low, it can lead to problems like low libido or difficulty with sexual performance.

Bone Density and Mood

Testosterone also helps keep your bones strong and supports a good mood. Low testosterone can lead to bone weakness and can make people feel tired or depressed.

Energy Levels

High testosterone levels are important for keeping energy, motivation, and physical ability up. Low testosterone is often linked to feeling tired and having trouble focusing or keeping up energy levels.

Why Boosting Testosterone Matters

Performance Enhancement

Higher testosterone levels help improve athletic performance, strength, and recovery from workouts. This means you can train harder and recover faster.

Body Composition

Testosterone helps reduce body fat and build lean muscle. This makes it important for athletes and bodybuilders who want to get stronger and leaner.

Aging and Testosterone

As people age, testosterone levels go down naturally. This can lead to muscle loss, more body fat, and a lower sex drive. Using things like prohormones or natural boosters can help keep testosterone levels higher as people get older.

Hormone Replacement Therapy (HRT)

Prohormones can sometimes be used as an alternative to Hormone Replacement Therapy (HRT) to increase testosterone without direct hormone injections. But they come with their own set of risks.

How Prohormones Affect Testosterone Levels

1. Initial Testosterone Boost

Short-Term Effects

• Increased Aggression and Drive: People often feel more motivated and focused after starting a prohormone cycle, which can be helpful during hard workouts.
• Performance Gains: Higher testosterone means more strength, better muscle pumps, and improved performance in the gym.

Increased Muscle Mass and Strength

• Rapid Gains: Users often see quick muscle gains because of the increase in testosterone. This happens because of better nitrogen retention and more protein synthesis.
• Training Adaptations: More testosterone helps your body adapt better to resistance training, which means improved recovery and growth over time.
• Impact on Protein Synthesis: More testosterone means faster protein synthesis, which is important for muscle recovery and growth.

2. Negative Feedback Loop

Impact on Natural Testosterone Production

• Testicular Suppression: Long-term use of prohormones can lower natural testosterone production by the testes, causing them to shrink if PCT isn’t done properly.
• Hormone Suppression Duration: This hormone suppression can last for weeks or even months after stopping prohormones, depending on how much and how long they were used.

Hypothalamic-Pituitary-Gonadal (HPG) Axis

Prohormones can disturb the HPG axis, which is the system that controls testosterone production in the body.

• Signal Disruption: Prohormones lower the signals from the hypothalamus and pituitary gland, which reduces natural testosterone production.
• Recovery Challenges: Bringing hormone levels back to normal after a cycle can be tough without proper PCT.
• Symptoms of Suppression: Signs that testosterone is too low include feeling tired, having low libido, mood swings, and losing muscle mass.

3. Estrogen Conversion and Side Effects

Estrogen Conversion

• Aromatization Process: Some prohormones get converted into estrogen by an enzyme called aromatase. This can cause side effects like gynecomastia (breast growth in males).
• Managing Estrogen Levels: Using Aromatase Inhibitors (AIs) can help control estrogen levels and reduce these side effects.
• Signs of High Estrogen: Symptoms of high estrogen can include water retention, mood swings, and increased body fat.

Other Side Effects

• Mood Swings: Changes in hormones can make people feel more anxious, irritable, or even depressed.
• Liver Toxicity: Since prohormones are processed by the liver, they can harm it if not managed with liver support supplements like milk thistle or N-acetylcysteine (NAC).
• Cardiovascular Concerns: Prohormones can negatively affect cholesterol levels, increasing LDL (bad cholesterol) and lowering HDL (good cholesterol), which may increase the risk of heart problems.
• Hormonal Acne: Hormonal changes during a prohormone cycle can lead to acne and other skin issues.
• Hair Loss: High levels of DHT can speed up hair loss in people who are already prone to baldness.

Post-Cycle Therapy (PCT)

Importance of PCT

Post-cycle therapy (PCT) is necessary to help the body recover after a prohormone cycle and bring natural testosterone levels back to normal.

Hormonal Recovery

PCT helps restart the body’s natural HPG axis to get testosterone levels back to where they should be.

Preventing Estrogen Rebound

After stopping prohormones, estrogen levels can stay high. PCT with SERMs and AIs helps stop estrogen from getting too high and keeps hormone levels balanced.

Typical PCT Components

Selective Estrogen Receptor Modulators (SERMs)

SERMs, like Nolvadex or Clomid, help keep estrogen from binding to receptors. This helps lower estrogen levels and bring back natural testosterone production.

Natural Test Boosters

Natural supplements like D-aspartic acid, fenugreek, tribulus terrestris, and zinc can help boost testosterone naturally.

Aromatase Inhibitors (AIs)

AIs like Arimidex reduce the amount of testosterone that gets converted to estrogen, helping with faster recovery and reducing side effects.

Dosage and Duration

A typical PCT lasts about 4-6 weeks. It’s important to get the right dose to avoid either not recovering enough or causing new imbalances.

Risks and Considerations of Using Prohormones

Potential Health Risks

Liver Support

Because prohormones are processed in the liver, liver support supplements like milk thistle and NAC are important to protect the liver during a cycle.

Hormonal Imbalances

Using prohormones for too long can cause hormone imbalances, like low natural testosterone and high estrogen.

Psychological Effects

Hormone changes can cause mood swings, more aggression, and even depression. It’s important to take care of your mental health while using hormones.

Kidney Stress

Prohormones can stress the kidneys, especially if you aren’t drinking enough water. It’s very important to stay hydrated during a cycle.

Legal and Regulatory Issues

• Banned Substances: Many prohormones are now banned in sports and are considered controlled substances.
• Regulatory Changes: Laws around prohormones have changed, and many that used to be legal are now banned.
• Risks of Buying Online: Buying prohormones online can be risky because you might get contaminated or fake products.

Who Should Avoid Prohormones?

Age Considerations

Teenagers and young adults should avoid prohormones because their bodies are still developing, and using hormones can lead to long-term issues.

Medical Contraindications

People with health problems like liver disease, high blood pressure, kidney issues, or mental health disorders should not use prohormones because they can make these conditions worse.

Safer Alternatives to Prohormones

Natural Testosterone Boosters

Resistance Training

Doing exercises like squats, deadlifts, and other compound movements can help boost testosterone naturally. High-intensity interval training (HIIT) also helps raise hormone levels.

Dietary Changes

Eating foods rich in healthy fats (like avocados, nuts, and olive oil), and getting enough zinc, magnesium, and vitamin D can support healthy testosterone levels. Avoiding too much sugar and processed food can also help.

Lifestyle Factors

Getting enough sleep (7-9 hours per night) is key to keeping testosterone levels high. Reducing stress through yoga, meditation, or other methods can also help keep hormones balanced.

Herbal Supplements

Herbs like ashwagandha, tribulus terrestris, tongkat ali, and maca root can help support testosterone levels and reduce cortisol, a stress hormone that can lower testosterone.

Benefits of Natural Methods

• Sustainable Health: Natural methods have fewer risks and help maintain good health long-term.
• Fewer Risks: Natural testosterone boosters don’t have the serious side effects that prohormones do, like liver damage.
• Holistic Approach: Combining exercise, a healthy diet, good mental health, and lifestyle changes leads to better overall health.
• Long-Term Viability: Natural methods can be used over the long term, making them more sustainable for health.

Tips for Responsible Prohormone Use

Consult a Healthcare Professional

Always talk to a doctor before starting a prohormone cycle to make sure it’s safe for you.

Medical Screening

Get blood tests before starting a cycle to check hormone levels, liver function, and kidney health. Regular tests during the cycle help catch any problems early.

Proper Dosage and Cycling

Cycle Length

Stick to a short cycle length (usually 4-8 weeks) to reduce the risks. Longer cycles can cause bigger issues like hormone suppression or organ damage.

Monitoring Health

Recognizing Warning Signs

Know the signs of liver stress—such as yellow skin (jaundice), extreme fatigue, or pain under your ribs. Also look for signs of hormone problems, like low sex drive, depression, or acne.

Using Liver Support Supplements

Hydration and Diet

Stay well hydrated and eat a balanced diet to keep your liver healthy. Avoid alcohol while taking prohormones to protect your liver.

Conclusion

Summary of Key Points

Prohormones can help boost testosterone temporarily, which helps with muscle growth, strength, and performance. However, they can also lead to long-term testosterone suppression and other health problems if not used correctly. PCT and liver support are essential for safe use.

Final Thoughts

Think carefully about the risks and benefits of using prohormones. Talk to a healthcare provider before starting to avoid long-term health problems.

Personal Health Priority

It’s always better to focus on long-term health over short-term gains. Safer options like natural testosterone boosters, along with proper exercise, diet, and lifestyle choices, are better for your health in the long run.
