Cellucor P6 Products

Cellucor P6 has launched 5 products in the P6 family. Here’s an overview of each P6 product and how it works:


P6 Alpha Testosterone Booster

P6 Alpha is the company’s cheapest P6 product. It provides basic support for testosterone, strength, and vitality at a competitive price point ($24.99). Each bottle contains 60 capsules, and you take two capsules daily to boost your testosterone.


According to Cellucor, P6 Alpha was specifically formulated to target key factors like nitric oxide production, stress, cellular energy production, and testosterone levels.

To target these areas, P6 Alpha contains:

Testfactor: Helps support testosterone production, muscular strength, and endurance.

DIM: Helps support estrogen metabolism by converting estrogen to less potent forms, which means less estrogen ends up affecting your body.

Fenugreek: A popular herb in traditional medicine, fenugreek is found in many testosterone booster supplements sold today.

Vitamins and Minerals: Cellucor P6 Alpha also contains vitamin D3, B6, folate, magnesium, and zinc. Some studies show men who are deficient in these vitamins and minerals tend to have lower testosterone production. Vitamin D3 and zinc are particularly important for testosterone.

According to Cellucor, P6 Alpha will boost testosterone, support strength, and increase vitality. That means you can look, feel, and perform at your best using natural ingredients.

Price: $24.99

P6 Alpha Advanced Testosterone Booster

If you’re willing to pay more, the P6 Alpha Advanced formula contains 90 capsules and a more powerful formula for twice the price of P6 Alpha ($49.99).


Like P6 Alpha, P6 Alpha Advanced claims to boost strength and testosterone using natural ingredients. However, the formula contains additional active ingredients we don’t see in the P6 Alpha formula.

In addition to Testfactor, DIM, and fenugreek, for example, P6 Alpha Advanced contains popular preworkout ingredients like ElevATP, Citrulline Nitrate, and SenActiv. These ingredients can boost nitric oxide production, widening blood vessels and boosting endurance during your workout.

Here are all of the ingredients in P6 Alpha Advanced and how they work:

All Ingredients in P6 Alpha: P6 Alpha Advanced contains the same core formula as P6 Alpha, which includes fenugreek, DIM, and Testfactor to boost testosterone and strength.

ElevATP: ATP is cellular energy, and ElevATP is designed to support power output at a cellular level. According to Cellucor, the ElevATP in P6 Alpha Advanced will support muscle size, strength, and increased power output.

Citrulline Nitrate (NO3-C): Citrulline nitrate is a blend of amino acids, nitrates, and performance boosting ingredients. The proprietary formula contains citrulline and nitrates for dual pathway nitric oxide support. That’s a fancy way of saying P6 Alpha Advanced supports healthy blood flow in multiple ways.

SenActiv: P6 Alpha Advanced contains SenActiv, a proprietary formula that helps support healthy muscle cells, cellular energy, performance, and muscular endurance.

Asian Ginseng: The final unique ingredient in P6 Alpha Advanced is Asian ginseng. A traditional plant used in types of Asian medicines, ginseng has been shown to support vitality, wellbeing, and alertness, making it a popular addition to preworkout supplements and endurance boosters.

Each bottle of P6 Alpha Advanced contains 90 capsules (30 servings). Cellucor recommends taking 3 capsules daily to support testosterone.

Price: $49.99

P6 Original

P6 Original is a testosterone booster formula priced at $89.99. It’s an all-inclusive formula to support multiple testosterone and performance goals.


According to Cellucor, P6 Original lets you naturally boost testosterone levels to increase strength, lean muscle mass, and vitality. As you get older, your testosterone levels drop. P6 Original aims to solve that while being a “safe and effective way to boost testosterone,” according to Cellucor.

Each two capsule serving of P6 Original contains 1,050mg of a proprietary formula called the P6 Testosterone and Performance Blend. That formula includes proven testosterone boosters like ashwagandha, fenugreek, and Longjack, among others. By taking all of these ingredients at once, you can support testosterone in multiple ways.

Here are all of the testosterone booster ingredients in P6 Original and how they work, according to Cellucor:

KSM-66 Ashwagandha: Used in traditional Indian (Ayurvedic) medicine for centuries, ashwagandha is a popular herb for stress and overall health and wellness. Today, many supplements use KSM-66 ashwagandha for its high purity and potency. Studies show KSM-66 ashwagandha can improve muscle size, strength, and natural testosterone levels in healthy adult males. KSM-66 ashwagandha may be particularly effective at fighting stress-induced testosterone loss. If stress is causing you to lose testosterone, then KSM-66 ashwagandha may be able to help.

Ovine Placenta Powder: Described as a natural HCG agonist, ovine placenta powder is a rich source of growth factors crucial for cellular growth, muscle growth, and recovery. Ovine placenta powder comes from sheep placenta.

LJ100 Long Jack Extract: Many natural testosterone boosters contain long jack extract, which has been shown to support testosterone in clinical trials. Studies also show long jack can enhance sports performance, promote free testosterone levels, and help keep the body in anabolism as long as possible. That means more muscle growth and more muscle cell activity than you otherwise would have.

Although P6 Original is priced higher than the two previous members of the P6 family, it also contains twice as many servings: each bottle of P6 Original contains 120 capsules, or 60 servings. Cellucor recommends taking 2 capsules daily to boost testosterone.

Price: $89.99

P6 Ultimate

P6 Ultimate is the second most powerful member of the P6 family. Priced at $160 for 30 servings, it’s also one of Cellucor’s highest-priced supplements overall. If you’re willing to pay a premium for maximum results, then P6 Ultimate may be the right choice for you.


Each 5 capsule serving of P6 Ultimate contains significant doses of testosterone boosting natural ingredients, cognitive enhancers, and performance boosters, among other ingredients.

Instead of only focusing on testosterone or muscle growth, P6 Ultimate focuses on multiple aspects of overall performance. By taking 5 capsules daily, you can optimize performance in multiple ways to achieve the best version of yourself.

P6 Ultimate mostly contains stronger doses of other ingredients in the P6 family. However, the formula is unique for two specific ingredients, including:

AlphaSize A-GPC: A popular nootropic and focus enhancer, AlphaSize is a unique version of AlphaGPC designed for maximum purity and potency. While other ingredients in P6 Ultimate are designed to boost testosterone and muscle growth, AlphaSize A-GPC is specifically designed to help with cognition and focus.

Zembrin: Zembrin is a nutritional supplement formula that helps with calmness and serenity. According to the manufacturer, Zembrin can deliver an “alert serenity that impacts mood, focus, and an overall sense of well-being.” The manufacturer markets Zembrin to e-sports athletes, elite athletes, and anyone else who wants to perform at the highest cognitive levels.

P6 Ultimate separates its formula into two blends, including the P6 Testosterone and Performance Blend (2,275mg) and the P6 Ultimate Cognitive and Pump Blend (1,225mg). The first blend contains ashwagandha, fenugreek, ovine placenta powder, stinging nettle root extract, and long jack, while the second blend contains Nitrosigine, arginine nitrate, AlphaSize A-GPC, and Zembrin.

P6 Ultimate is priced at $159.99 per bottle and contains 150 capsules (30 servings) per bottle.

Price: $159.99

P6 Ultimate GH

P6 Ultimate GH is a growth hormone supplement designed to support human muscle growth and metabolism. The formula stimulates protein synthesis, reduces protein breakdown, and enhances fat metabolism using ingredients we don’t see in any other P6 formulas.


Unique ingredients in P6 Ultimate GH include shilajit, L-arginine, and velvet bean seed extract. The formula also contains some of the same ingredients found in other P6 formulas, including ElevATP, long jack extract, and DIM.

Overall, P6 Ultimate GH aims to be the ultimate formula for boosting endurance, muscle development, testosterone, and growth hormone production. You get all of the strength and testosterone boosting effects of other members of the P6 family, but you also get added ingredients for growth hormones – all in one convenient formula.

P6 Ultimate GH is priced at $199.99 and comes with 30 servings. You take 6 capsules daily to support the active effects.

Here are some of the largest active ingredients in P6 Ultimate GH and how they work, according to Cellucor:

L-Arginine and L-Lysine: L-arginine and L-lysine are two amino acids linked to growth hormone production. According to Cellucor, the amino acids work in combination to support an increase in pituitary release of growth hormone. Your pituitary gland produces growth hormone naturally. As you get older, growth hormone production declines. The L-arginine and L-lysine in P6 Ultimate GH aim to reverse that trend.

Shilajit: Shilajit is a natural extract that has been shown to boost total and free testosterone, according to Cellucor. Cellucor also claims the shilajit in P6 Ultimate GH will increase cellular energy and support increased endurance, among other effects.

Velvet Bean Seed Extract: Velvet bean seed extract contains an active ingredient called L-dopa. The velvet bean seed extract in Cellucor P6 GH is standardized to contain 60% L-dopa. L-dopa may work in tandem with L-arginine to help support growth hormone production. Studies also show velvet bean extract supports acute plasma growth hormone levels by targeting the hypothalamus, helping to release growth hormone releasing hormone (GHRH). That’s a fancy way of saying velvet bean seed extract targets growth hormone production in multiple ways.

ElevATP: Like certain other members of the P6 family, P6 Ultimate GH contains ElevATP, a proprietary formula designed to boost energy at the cellular level. Derived from ancient peat and apple, ElevATP uses trace minerals and polyphenols to help increase power output and training volume by supporting mitochondrial ATP.

Long Jack: Several other P6 supplements contain long jack, and P6 Ultimate GH is no exception. The long jack in Cellucor P6 GH can purportedly promote increased lean muscle mass, promote an anabolic state, and inhibit sex hormone binding globulin (SHBG), among other benefits. Cellucor also claims it can help maintain healthy cortisol levels while boosting sexual health and wellbeing, among other benefits.

DIM: Each serving of P6 Ultimate GH contains 100mg of DIM, which affects estrogen metabolism by converting the most powerful types of estrogen into weaker forms.

Together, these ingredients can support testosterone production, endurance, cellular energy, and more in various ways.

Price: $199.99

Scientific Evidence for Cellucor P6

Cellucor uses science-backed ingredients to formula its testosterone boosting supplements, including DIM, fenugreek, vitamins, minerals, and a proprietary formula called Testfactor. We’ll review some of the science supporting these ingredients below.


Several P6 supplements contain an ingredient called Testfactor. Designed specifically to boost testosterone, Testfactor can purportedly boost performance, endurance, muscle growth, muscle strength, energy, and focus by raising testosterone. To achieve these benefits, Testfactor contains a combination of three proven testosterone supporting ingredients, including tongkat ali, Asian ginseng, and horny goat weed.

Studies show that Asian ginseng may help with testosterone. In one review, researchers found multiple studies showing ginseng usage was linked with higher testosterone levels. In this study, for example, researchers gave ginseng or a placebo to 66 patients, and researchers found ginseng significantly increased levels of plasma total and free testosterone.

Tongkat ali also appears to impact testosterone, possibly by affecting stress levels in your body. In this 2013 study, for example, researchers found tongkat ali helped with stress hormones and psychological mood state in moderately stressed subjects. If stress is causing your testosterone levels to drop, then tongkat ali may be able to help.

Horny goat weed has its name for a reason: it’s been used for centuries as a libido booster, testosterone enhancer, and aphrodisiac. Modern studies show that horny goat weed (which contains an ingredient called icariin) may have libido boosting effects. However, few studies have shown significant increases in testosterone associated with horny goat weed. It may raise sexual drive by boosting blood flow, but it doesn’t seem to significantly raise or lower testosterone. Nevertheless, one study found horny goat weed had similar effects to sildenafil for boosting erection quality (sildenafil is the active ingredient in Viagra).

Many people take diindolylmethane (DIM) to boost testosterone. In this 2016 study, researchers found that DIM decreased sperm quality and reduced estrogen levels in rats. Researchers found DIM inhibited an enzyme called aromatase that converts testosterone to estrogen. By inhibiting this enzyme, you can prevent your body from turning excessive testosterone into estrogen. That means more free testosterone circulating through your body.

Other proven ingredients in P6 supplements include fenugreek, vitamin D3, and zinc, all of which have been linked to testosterone in several studies. Men who are deficient in vitamin D3 and zinc, for example, tend to have lower testosterone levels than men who have sufficient levels of these vitamins and minerals.

P6 Ultimate contains a proprietary formula named Zembrin. Popular for the last decade, Zembrin is a mood booster found in many supplements. The ingredient has been clinically studied to verify it works as advertised. In one study, the manufacturer found that 25mg of Zembrin reduced anxiety-related activity of the amygdala and associated anxiety circuity within 2 hours of administration. In another study, researchers viewed the effects of Zembrin using quantitative electroencephalogram (EEG) monitoring, psychometric tests (CPT and NCT), and a questionnaire, indicating Zembrin supported electrical activity within the brain. Because of these results, Zembrin is popular among athletes of all levels seeking a cognitive boost.
