The Ultimate Anabolic Testosterone Booster from Alpha Pro Nutrition is here!

GR8TEST is a new, state of the art testosterone booster that is much more – it’s actually three products in one: a test booster, estrogen blocker and nitric oxide booster! This is a product that was created to be exclusive, powerful and effective. Alpha Pro uses only superior ingredients and effective, research proven dosages – you will not find a product with the “Alpha Pro” name on it that skimps on dosing or ingredient quality.

When it comes to building muscle, testosterone is really what it’s all about. Long hailed as the “King of Hormones” it is considered by many to be the body’s most powerful anabolic hormone. This is the hormone that makes you a man – it not only promotes growth but also the development of sexual characteristics. Increasing levels of testosterone production – safely and naturally – means increased muscle growth and strength. Furthermore, as we age, our test levels decline – making supplementation an unquestioned requirement, especially if building new muscle is your priority. However, GR8TEST is not just another test booster – we knew that to be effective, we would have to deal with the conversion of excess testosterone to estrogen, so GR8TEST is not only a powerful test booster; it’s a potent estrogen blocker as well! This means the typical side effects of excessive estrogen levels are controlled.

We chose to take GR8TEST one step farther. What’s the one thing most lifters look for in the gym? The Pump, of course! Nothing feels quite as satisfying as a tight, full, exploding pump! The increased blood flow that produces the pump does more than just swell your working muscles – it brings much needed oxygen and nutrients to those tired muscles, promoting between-set recovery as well as setting up post workout recovery and growth. It also means – and this is huge – that with the increased levels of testosterone you’ll experience from using GR8TEST, the higher levels of nitric oxide brought about by Alpha Pro’s advanced nitric oxide enhancing complex transports free testosterone to your working muscles and the extended pump you’ll experience from this potent product will actually keep the test entrenched in your muscles for a longer than normal period of time.

It should be clear after reading our ingredient breakdown that GR8TEST is NOT just one more test booster but instead an advanced formula carefully designed to bring about maximum results not only in the production of testosterone but also nitric oxide and that one complements the other – the bottom line is you will experience results like you never have before!

GR8TEST Ingredient breakdown:

D-Aspartic Acid

Research proven to increase Test Levels! Provides Research Backed Dosage – No Other Product on the Market Can Match GR8TEST DAA Dosing: 3,500mg per scoop!

Commonly referred to as DAA, this is an amino acid that is heavily involved in endocrine system function. Normally found in the pituitary gland and the gonads, DAA activates the release of testosterone and luteinizing hormone. DAA has been the subject of both rat and human research on the results of oral administration of DAA and its effects on testosterone levels. What’s most important is the effect on human test subjects, after all, we aren’t rats and we’re not going to react quite the same way! The true test of an effective ingredient is what happens in the real world where hard training bodybuilders and athletes expect real results. The male test subjects in this study were given one daily dose each morning of 3 grams (which as it turns out is about the same as the dose used in the rat studies).

What were the results?

The male test subjects realized an increase of 42% in testosterone production and as well as an increase in LH of33% after only 12 consecutive days of use. Additionally, blood testosterone levels (not LH) remained elevated for 3 days after discontinuing the use of DAA. To summarize: the research suggests that, for the majority of men, a single daily dose of 3 grams will stimulate dramatic effects by the second week of use, elevating testosterone production and luteinizing hormone and by as much as 50%. Of course, GR8TEST contains the research suggested dose of 3 grams – a huge 3250mg per scoop to be exact – more than any other product currently on the market! This is the Alpha Pro philosophy – we believe that hard training, elite bodybuilders and athletes, as well as any serious lifter, demand effective levels of the nutrients they lay down their hard-earned money for – after all, you’re paying for results and Alpha Pro delivers!

Estroblock Blend

Synergistic complex of proven, effective ingredients to control Estrogen and increase test production!

L-Carnitine L-Tartrate

The amino acids l-lysine and L-methionine combine to form L-Carnitine, the primary function of which is to utilize stored fat for energy by transporting it to the mitochondria to be burned as fuel for the body. L-Carnitine L-Tartrate is actually one of several versions of L-Carnitine, indications are that it is superior to the other available forms. In this case, L-Carnitine is bound to tartrate, which is an ester of the organic compound known as tartaric acid – used primarily to improve absorption of the compounds it’s attached to.

L-Carnitine L-Tartrate has the exclusive benefit of promoting muscle recovery – by this mechanism of action it also promotes testosterone levels indirectly by increasing the number of available androgen receptors. Androgen receptors oversee the effect of free testosterone on protein synthesis, so an increase in the number of available androgen receptors means greater utilization of free testosterone in the bloodstream. As we have stated above, testosterone is one of, if not the, body’s strongest anabolic hormones, yet, on average, 98 percent of all testosterone found in the body is known as bound testosterone, and it’s completely unavailable – period! On the other hand, the remaining 2% – known as free testosterone – is the only usable testosterone available for muscle growth.

Here’s the research: Two cross-over, placebo-controlled clinical trials demonstrated that oral L-carnitine-L-tartrate supplementation can decrease the level of muscle tissue damage caused by exercise-thereby promoting recovery. Decreased muscle damage means an increase in the number of available androgen receptors that can bind with testosterone, creating a more anabolic environment that’s conducive for muscle growth. This research not only supports the use of L-Carnitine L-Tartrate for improved recovery but also indicates the role of this compound in manipulating test levels.

Nettle Root (Urtica Dioica)

Also known as stinging nettle, this is a perennial flowering plant, native to Europe, Asia and North America. Why is it also called Stinging Nettle? Many of the plants in this species have stinging hairs on them – when touched by an animal or person, they create a stinging sensation by injecting histamine into the person or thing touching them. Recent research has shown Nettle to be an effective estrogen blocker that inhibits the production of aromatase – this in turn decreases estrogen production. Nettle Root has other actions in the body, primarily the ability to prolong blood levels of free testosterone. As indicated above, only about 2 percent of testosterone in the average man is free, “active” testosterone. The fate of free testosterone falls into the hands of SHBG, (or, sex hormone binding globulin, a glycoprotein) which binds to free testosterone and makes it unavailable for anabolic stimulation. Nettle Root works to bind to SHBG, sparing the free testosterone and making it available for creating the anabolic environment conducive to muscle growth.

Chaste Tree Fruit Extract (Vitex Agnus Extract)

Also known as Vitex agnus castus and Agnus castus, Chaste Tree is a plant located in Asia and in the Mediterranean countries. Research supports its use as a testosterone booster via reduction of prolactin release. It’s thought to exert it’s mechanism of action by inhibiting activation of the dopamine 2 receptor, causing a decrease in release of prolactin. In men, it’s believed lower prolactin levels will stimulate testosterone production.

Maca Root

Maca originates in the mountains of Peru and is also known as Lepidium meyenii and Lepidium Peruvianum. Maca naturally contains DIM (Diindolylmethane), a phytochemical that’s found in cruciferous vegetables such as broccoli and cabbage. DIM has been research shown to effectively control estrogen levels. Additionally, several studies support the use of Maca as a potent stimulator of sexual desire. One study utilized male test subjects ranging in age from their 20’s to mid-40’s. The 12-week study used 1500mg-3000mg of Maca and a placebo. At the end of this study, those receiving Maca tested as having “increased seminal volume” than those given the placebo. Additionally, real-world, in the gym “research” indicates Maca can improve workout stamina, leading to better workout performance.

Chrysin Extract

Chrysin (5,7-dihydroxy flavone) is the primary active ingredient derived from the passion flower (Passiflora coerulea) plant, containing anti-aromatase and antioxidant flavones. Chrysin has a long history of medicinal use for increasing libido. As an aromatase inhibitor Chrysin acts in three distinct ways to block estrogen: first, it prevents the binding of estrogen to estrogen receptors, secondly, it blocks the conversion of testosterone to estrogen and finally it reduces estrogen production.

Longjack Root Extract (Eurycoma longifolia)

Longjack is an herb that originates in the tropical rainforest of Indonesia. Promising new research indicates that Longjack has two primary benefits when it comes to estrogen control and test production. First, it inhibits the conversion of testosterone to estrogen and secondly, it’s been shown to increase your body’s levels of free testosterone. It’s believed that Longjack increases levels of free testosterone by binding to SHBG and therefore preventing SHBG from binding to the free test – this means more of the free test is available for muscle growth.

DIM (3,3′-Diindolylmethane)

A phytonutrient found in cruciferous vegetables , DIM promotes the effective metabolism of estrogen by promoting the conversion of estradiol into metabolites that ignite fat loss by stimulating the hormones that release stored fat to be used as energy. Dim supports testosterone production by keeping estrogen under control – testosterone is not converted into estrogen.

As you can see, Alpha Pro has created a formula that works synergistically to promote test production, keep free test active in the bloodstream and block estrogen by various mechanisms. Every ingredient is in GR8TEST for a reason – you won’t find any “filler” compounds in any product created by Alpha Pro Nutrition.

Nitirc Oxide Accelerator Blend

Powerful blend of N.O. Activators to experience intense pumps. Enhanced Nutrient/Oxygen delivery. Nitric Oxide blend promotes extended circulation of free testosterone!

Agmatine Sulfate (AgmaMAX™)

After extensive testing, we chose AgmaMAX brand Agmatine Sulfate to be used exclusively in Alpha Pro products – we are committed to using only the best ingredients in all Alpha Pro products.

A relative newcomer to the supplement world, Agmatine is a byproduct of Arginine decarboxylation that is produced and stored in the brain with several benefits that go well beyond the fabled “Pump”. However, Agmatine has the ability to create an intense, long lasting pump; in fact it’s becoming clear that it outperforms arginine in this regard. It does this in several ways: by pulling glycogen and water into the muscles, thereby increasing glycogen stores and creating an extremely full-looking muscle. This has practical benefits as well – more stored glycogen means more cellular energy will be available for training needs. Additionally, it increases N.O. levels by inhibiting certain types of the enzyme nitric oxide synthase – there are several – which then promote greater Nitric Oxide production.

The benefits don’t end there, as Agmatine promotes the production of insulin, one of the major anabolic hormones in the body. It also helps control cortisol, a major catabolic hormone released during periods of emotional stress and physical stress – such as when you work out. If that’s not enough, Agmatine possesses cognitive benefits, helping to control depression, improve mood and enhance mental clarity.

Citrulline Malate

Citrulline Malate combines the amino acid citrulline with malate, an ester of malic acid – an organic dicarboxylic acid found in wines, sour apples, and other fruits. L-Citrulline is one of three amino acids in the Urea cycle (also including L-Arginine and L-Ornithine), which helps your body eliminate ammonia, a waste product of protein digestion. Once absorbed, Citrulline converts into L-Arginine, this in fact makes it a superior method of getting L-Arginine into the bloodstream. Once converted into arginine, it’s then converted into nitric oxide.

Of course, increased N.O. levels mean not only a better pump but also superior nutrient and oxygen delivery to your working muscles as well as improved removal of waste products. Improved nutrient delivery means you have better between set recovery and more workout endurance for increased exercise performance. It also means the increased test levels caused by using GR8TEST will be delivered to your working muscles.

Arginine AKG

Also known as Arginine alpha-ketoglutarate, or AAKG, this is a type of the amino acid arginine that consists of two arginine molecules attached to one alpha-ketoglutarate molecule. Alpha-ketoglutarate is a type of L-Glutamine, one of the most important amino acids for recovery and the most abundant amino in muscle tissue – 65% of your muscles are in fact glutamine. AAKG results in dramatically improved absorption of arginine which in turn increases N.O. production – meaning a greater pump! Additionally, research has shown that AAKG improves recovery time and promotes a better mind-muscle connection.

L-Arginine – L-arginine

A precursor for nitric oxide, is classified as a semi-essential or conditionally non-essential amino acid. When nitric oxide is released, it widens the blood vessels by relaxing the muscles of their walls, which reduces blood pressure and increases blood flow to your working muscles – not only providing a intense pump but also oxygen and nutrient delivery.

Whats the recommended dosage?

For a potent testosterone boosting effect take one full scoop of GR8TEST upon awakening or 1/2 scoop in the morning and another 1/2 before bedtime. For a pre-workout testosterone boosting effect take one full scoop 30-60 minutes before you session. Do not exceed one scoop in a 24hr period.
