Under The Microscope: T-Up Black

Under the Microscope

D-Aspartic Acid

Also known as D-aspartate, this amino acid is produced in the pituitary gland where it stimulates the release of luteinizing hormone (LH). LH travels via the bloodstream to the testicles where it boosts testosterone production. D-aspartate is also produced in the testes and acts on Leydig cells-special cells in the testicles that produce T-to increase the production of test as well as sperm. In a recent study, Italian scientists gave 43 men either 3 grams of D-aspartate along with vitamins B6 and B12 and folic acid every morning for 12 days or a placebo that contained the same B vitamins but no D-aspartate. They reported in the journal Reproductive Biology & Endocrinology that subjects taking the D-aspartate supplement increased their testosterone levels by more than 40%.

Grade: Rating Rating Rating Rating Rating

Reason: Research in humans and ani-mals supports its ability to boost T levels. If more human studies show similar results, the grade will hit five microscopes.

Folic Acid

This is the synthetic form of the B vitamin folate, which assists with the body’s use of Daspartate. Folate is also critical for the production and maintenance of new cells. One way muscle grows is by replacing damaged muscle cells with new ones called satellite cells, which grow larger and stronger than the old ones. Folate is also required to make DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Lifting weights signals the DNA in muscle nuclei to increase muscle-protein synthesis by a special type of RNA that sends the message to make more muscle protein.

Reason:Folic acid is a crucial vitamin for muscle growth but its role in increasing testosterone levels is less known.

Vitamin B12

This B vitamin appears to be important for enhancing D-aspartate utilization in the body. B12 is also involved in numerous physiological processes such as the production and use of energy from dietary fat and protein, especially during exercise. When your body is less efficient at using energy, not only are you more fatigued but the calories you eat are more likely to be stored as fat. Vitamin B12 also aids in the production of hemoglobin, which is critical for energy production during workouts.

Reason: This B vitamin is crucial for any male, especially those who train regularly. How it boosts test levels is currently not well understood.

Massularia Acuminata

Also known as Ijebu chewing stick, the stems and roots of this medium-size African shrub are traditionally used as an aphrodisiac, likely due to its testosterone-boosting properties. Nigerian scientists gave rats drinking water dosed with massularia acuminata extract or plain water for 21 days. They reported in the Journal of Ethnopharmacology that the group receiving the extract had significantly higher LH and test levels than the group receiving plain water.

Grade: Rating Rating Rating Rating

Reason: Anecdotal evidence and animal research supports the theory that massularia significantly boosts T levels, yet research in humans is lacking.
