Pure Test Information (Test Boosters/Hormone Regulation)

Pure Test by

Manufactured by:
Redefine Nutrition

Serving Size: 1 Capsule
Servings Per Container: 120

Active Ingredients:
Aspartic Acid (DAA) 500 mg

Other Ingredients: Gelatin, Silica, Magnesium Stearate, Stearic Acid

Bottle recommended use: Take 4-6 capsules daily for 30 days consecutively. Take every night at bedtime to maximize effectiveness as a testosterone elevator. For optimal results use for 6-12 weeks. For extreme results take two servings spaced 12 hours apart for 4-8 weeks. Do not use for more than 90 days consecutively.

There are plenty of claims out there about "natural" supplements that boost testosterone. Most of them, have been proven to be false, and those that remain are still--for the most part--inconsistently proven.

The same applies to DAA. There is research supporting this amino acid as a neurotransmitter and neuroendocrine agent in men, rats, and reptiles. There is no documented evidence that DAA would increase testosterone in women. In fact, in the lizard study, testosterone decreased in female lizards, though estrogen was elevated.

There appear to be benefits to mental function, and possibly protective effects against certain psychological states, but it is unknown what effect DAA will have long-term. The long-term safety of supplementing DAA has not been studied; neither has the therapeutic range. It should be noted that higher doses did not generate significantly higher testosterone response. Thus, it is critical (yes, I am using that word again) that consumers monitor changes in mood, concentration, and physical symptoms.

At the first sign of gynecomastia or mood changes, DAA use should be discontinued. The effect of DAA on developing brains and sexually immature subjects has not been studied in humans. Therefore, DAA should not be given to children or adolescents.

D-Aspartic Acid (DAA)

Aspartic acid is a non-essential amino acid, meainingit can be synthesized by th body. Aspartic acid is found in:

Animal sources: luncheon meats, sausage meat, wild game

Vegetable sources: sprouting seeds, oat flakes, avocado, asparagus[citation needed], young sugarcane, and molasses from sugar beets.

Dietary supplements, either as aspartic acid itself or salts (such as magnesium aspartate)

The sweetener aspartame (NutraSweet, Equal, Canderel, etc.)

D-Aspartic Acid (DAA - one of the two form of Aspartic Acid) is present in neuroendocrine tissues of humans and plays a role in the synthesis of both LH (Luteinizing hormone, also known as lutropin) and testosterone.

Supplementation with 3 grams (3,000mg) per day resulted in a 33% testosterone increase of 33%. While this might seem impressive, a 33% increase is unlikely to provide any real training boost or visible results. Added to this is that the majority of supplement containg DAA and claiming to be the 'next best thing' typically have a much less than 3g dose.

The straight scoop seems to be that as far as a test booster, DAA isn't that great. You have to take a huge dose for a relatively small effect.


Gelatin is a tasteless substance created from collagen found in animal skin and bones. It is used to thicken liquid in processed foods as well as having applications in photography, cosmetics, and pharmaceuticals. Gelatin is found in many forms of candy, marshmallows, Jell-O, and some types of yogurt. Gelatin can be bought in many grocery stores for use in home cooking. In the vast majority of cases, gelatin is not harmful to the consumer.

Magnesium Stearate

Magnesium stearate is often used as a diluent in the manufacture of medical tablets, capsules and powders. In this regard, the substance is also useful, because it has lubricating properties, preventing ingredients from sticking to manufacturing equipment during the compression of chemical powders into solid tablets.

Magnesium stearate is the most commonly used lubricant for tablets. Studies have shown that magnesium stearate may affect the release time of the active ingredients in tablets, but not that it reduces the over-all bioavailability of those ingredients.

Silicon Dioxide (Silica)

The chemical compound silicon dioxide, also known as silica, is an oxide of silicon. Silica is most commonly found in nature as sand or quartz.

Silica is common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications. It is the primary component of diatomaceous earth which has many uses ranging from filtration to insect control. It is also the primary component of rice husk ash which is used, for example, in filtration and cement manufacturing.

Stearic Acid

Stearic acid is the saturated fatty acid with an 18 carbon chain and has the IUPAC name octadecanoic acid. It is a waxy solid, and the salts and esters of stearic acid are called stearates. It occurs in many animal and vegetable fats and oils, but it is more common in animal fat. The important exceptions are cocoa butter and shea butter, whose fatty acids consist of 2845% stearic acid.

Stearic acid is used in making candles, plastics, dietary supplements, oil pastels and cosmetics, softening rubber, and hardening soaps. Stearic acid is used in aerosol shaving cream products. It is used along with simple sugar or corn syrup as a hardener in candies and to form margarines, shortenings, spreads, and as a cream base for baked products.

Even though stearic acid is a saturated fat, studies have suggested that it has little effect on blood cholesterol levels, because such a high proportion is converted to oleic acid.
