Maximize Testosterone for Muscle & Strength Gains

Hit a Plateau?

You train hard in the gym. Your diet is loaded with protein. Despite this, your gains are coming slowly and you feel stuck on a plateau.

If you've had this happen, then the issue may well be your testosterone levels.

Low test levels can hinder your muscle & strength gains, slow down recovery, and reduce your mental fitness. A proven test booster can be a game changer.

What Is The Answer?

Centrapeak is a low test booster that helps you to maintain peak vitality, mental strength, and physical performance.

It uses an all-natural, cutting edge formula to help you reduce stress, build muscle, and burn fat.

If you're serious about getting results in the gym then Centrapeak should be in your stack.

Unlock Your Gains

Attaining your ideal physique takes more than just eating clean and training hard. If you're stressed, you may find it harder to build muscle and your recovery time may be longer. High cortisol levels can lower testosterone, resulting in lower energy, motivation and mood.

Centrapeak is particularly good at combating stress. It's the only test booster that genuinely focuses on improving your cognitive wellbeing, in addition to boosting your physical performance.

Centrapeak has been designed to help you:
  1. Increase strength - Smash new PBs and have stronger lifts in the gym.

  2. Boost muscle growth - Develop your muscle mass in a natural way.

  3. Recover Faster - Bounce back from hard workouts faster.

  4. Cut Fat - Turn your metabolism into a fat-burning machine.

  5. Get 'In The Zone' - Experience improved mental strength, focus, confidence, and resilience to stress.

How does Centrapeak Benefit Bodybuilders?

Elevate Testosterone

Centrapeak will directly increase your testosterone in three ways:

  • Leydig cell stimulation - Leydig cells help you produce testosterone in the presence of the luteinizing hormone (LH). Certain ingredients in Centrapeak support this process, helping you to maintain peak test production.
  • Blocks SHBG - Only about 2% of your total testosterone in the body is free. The other 98% is bound to a protein called Sex Hormone-Binding Globulin (SHBG), which renders testosterone inert. As you age, you have more SHBG and less free testosterone. Centrapeak helps to increase your free T levels by reducing levels of SNBG.
  • Reduces estrogen - Centrapeak uses natural aromatase inhibitors which block the conversion of testosterone to estrogen. What's more, Centrapeak helps to directly reduce estrogen activity in the body.

Increase Metabolic Rate

The beauty of having more testosterone is that you'll burn fat more easily.

When your test levels are higher, you'll naturally gain more lean muscle.

With more muscle mass, your basal metabolic rate will rise.

This will allow you to burn calories more efficiently and will help you to maintain lower body fat.

Reduce Cortisol

Stress takes many forms. It's not just emotional stress that can hinder your gains, but physical stress from your workouts too.

The main problem lies in cortisol, the principal stress hormones. It negatively impacts your test, promotes inflammation, and slows down muscle recovery.

What's worse, cortisol encourages fat gain, meaning you'll have a hard time staying lean when you're stressed.

By inhibiting cortisol production, Centrapeak helps you feel better, recover faster, and achieve that lean and envious physique that you've been working hard towards.

Optimize Neurotransmitters

Centrapeak utilizes ingredients that support:

  • Serotonin
  • Dopamine
  • GABA

Dopamine is critical for having high motivation and focus. It's also what gives you that feeling of reward and pleasure after you complete a certain goal. E.g. after having a great workout.

Serotonin and GABA, on the other hand, make you more relaxed and at ease.

They help you stay in good mood and stress-free, which is a mindstate linked to lower stress levels.

Why is Centrapeak Different?

There are many test boosters on the market. Some work, others don't.

But none are specifically made to optimize your mental state like Centrapeak.

It's true that higher test levels will naturally put you in a better mood. But Centrapeak went a step further by adding ingredients that directly improve your mental strength and cognitive well-being.

When you're in a positive headspace, positive behaviors will follow.

Imagine the feeling of:

  • Being motivated to hit the gym every day.
  • Getting the most out of your every workout.
  • Having no cravings for junk, and being motivated to stay on track with your diet.

If you want to experience these benefits, Centrapeak is the testosterone booster for you. Once you start using Centrapeak, your stress levels will be lower, your workouts better, and you'll achieve your goals faster.

Key Ingredients For Strength & Muscle Growth

Centrapeak uses ingredients that have been proven through clinical research to boost test levels naturally.


Zinc is a mineral that your body needs to produce testosterone, build muscle, maintain healthy immune system, and countless other functions. You can get it from foods like shellfish and beef steak.

A zinc deficiency will slow down your recovery and your gains. About 2 billion people worldwide have sub-optimal levels of this critical mineral.

Benefits you'll gain from zinc supplementation include:

  • Faster muscle growth
  • Better recovery
  • Higher test levels
  • Increased DHT (another powerful masculine hormone)

In addition to this, zinc is shown to prevent drops in testosterone in athletes. In other words, if you train hard, your test levels could temporarily go down, but zinc prevents this from happening.

Centrapeak provides 20mg of zinc per day. This dosage ensures your needs for this mineral are fully covered.


Vitamin D3

The research around the sunshine vitamin, D3, has been heating up in recent years. Simply because it offers so many potential health benefits.

Vitamin D can help you with:

  • Muscle building - Vitamin D is found in every cell in your body and is needed for optimal muscle protein synthesis.
  • Anabolic Hormones - Vitamin D can raise both your total and free T levels.
  • Mood - Vitamin D is highly effective at combating Seasonal Affective Disorder (SAD) and improving your mood and well-being.

The standard recommended dosages for vitamin D are shown to be miscalculated and too low. Higher dosages of 3,300-8,000IU per day offer optimal benefits for test and muscle recovery. Centrapeak includes 3,300IU which is a dose shown in studies to be safe, and effective, to take long-term.

Vitamin D3


Research shows that boron can not only raise your free testosterone but also:

  • Boost physical performance
  • Decrease Sex Hormone-Binding Globulin (SHBG)

By inhibiting SHBG - which is responsible for making most of the testosterone unusable by your body - boron effectively increases your free test levels and improves your performance in the process.

An ideal dose of boron is somewhere around 10mg, which is the dosage Centrapeak uses. However, even doses as low as 2.5mg of boron are shown to increase androgen levels and increase strength in 1RM squats and bench press.

In addition to its test boosting properties, studies show that boron also boosts your short and long term memory, focus, and cognition. Making it an ideal ingredient for a bodybuilder who wants to improve all aspects of his performance.



Ashwagandha is packed full of steroidal lactones and compounds that boost your libido and support health.

Key Ashwagandha benefits include:

  • Increases testosterone levels
  • Improves muscle mass, strength, and power
  • Relieves stress
  • Improves fertility
  • Supports vitality and energy levels

According to research, Ashwagandha can raise your test levels and muscle strength in as little as 2 months.

As an adaptogen, Ashwagandha will make you more emotionally robust. When taking this herb, you'll notice you can handle stress better.


Mucuna Pruriens

Mucuna Pruriens will increase your dopamine levels. This is critical for having high motivation and energy to stay consistent with your workouts.

What's more, Mucuna interacts with certain receptors in the brain which stimulate the production of testosterone. As such, Mucuna pruriens gives you a one-two punch where it boosts your muscle mass both directly and indirectly.

Mucuna Pruriens


Magnesium is another vital mineral that supports your masculine health. It achieves this in several ways:

  1. Boosts total T levels
  2. Increases free testosterone by blocking SHBG
  3. Helps with muscle recovery
  4. Improves muscle oxygenation for better muscle pumps
  5. Stabilizes mood and helps with the production of key neurotransmitters

Soil depletion and modern farming methods means that magnesium deficiency is common these days. You could risk having sub-optimal test levels if you don't get enough magnesium daily.

Centrapeak includes 50mg of high quality magnesium citrate, which is equivalent to 200mg of less bioavailable (but more common) magnesium oxide.



I3C is a natural compound found in broccoli. It breaks down into DIM and several other compounds in your body where it exerts its benefits, including:

  • Blocks estrogen activity - less estrogen means more testosterone.
  • Keeps you lean - estrogen can lead to man boobs and belly fat. Indole-3-Carbinol helps you to avoid that.
  • Increased muscle mass - With less estrogen and more testosterone, you'll reap better results from your workouts.

I3C is superior to isolated forms of DIM. I3C is natural and is proven to safely reduce estrogen while promoting your anabolic hormones. DIM, on the other hand, has some controversy behind it as it was shown to increase estrogen in some studies.
