Boost testosterone levels with D Aspartic Acid (DAA)

D Aspartic Acid is an essential amino acid that’s a key ingredient in Bulk Nutrients' Test Max and is used in various testosterone boosting anti-estrogen supplements.

D Aspartic Acid has been shown to improve hormone function with significant effects. In one trial using daily doses of 3.12g, 87% of participants experienced increased hormone levels, with an average increase of LH levels by 33% and testosterone by 42% (Topo 2009).

D Aspartic Acid can be an effective supplement for building muscle in males. Muscle and fat growth is directly linked to testosterone levels with higher testosterone levels improving the ability to build muscle.

D Aspartic Acid works best when paired with Diindolylmethane to ensure no negative impacts from increased estrogen.

D Aspartic Acid Reviews

    Works and taste good

    Used in part of a PCT and worked well. Great to also use stand alone, taken at night before bed I've found works the best.

    Flavor is lemon'ish. Mixes easy with water.

    Ideally used for men who are over the age of 30, vegans and people suffering with lower than their usual testosterone.

    Good protocol to run is 1 dosage PM before bed. If you were to run it twice a day, have it either post workout or AM. Usually run for 3-4 weeks, then take same amount of time off.

    NOTE: If you regularly eat meat / dairy, then this product may no suit you, as they're naturally high in Aspartic Acid.
