Naturally boost your testosterone and growth hormone levels without significantly increasing estrogen.*1
When it comes to naturally boosting your testosterone and growth hormone levels without the unwanted byproduct of elevated estrogen production, few natural products can compete with the proven effects of d-aspartic acid.
Found naturally in the testes, pituitary gland, and the hypothalamus, d-aspartic acid plays a central role in the production and regulation of male hormones that directly enhance athletic ability, size, and strength.2
Research particularly supports the powerful effects that D-AA has on promoting the production of four key hormones:
Testosterone: Increased testosterone levels have a positive effect on strength, stamina, muscle retention, and fat loss.1 The result is a lean, hard physique and increased physical performance across the board.
Luteinizing hormone: Along with Follicle-Stimulating Hormone, Luteinizing Hormone is a Gonadotropin because they directly stimulate the gonads (testes) to increase testosterone and sperm production.1,3
Growth hormone: Growth hormone promotes deep, restful sleep, which is extremely important for maximizing healing, recovery, and lean muscle growth. Growth hormone also has a direct role in rebuilding muscle and body tissue when damaged by intense exercise and working out.1
Follicle-stimulating hormone: In addition to increasing testosterone production in the testes, FSH regulates many of the developmental, growth, and reproductive processes of the body and is essential to maintaining and quickly adding lean muscle mass.2,3
Testosterone > Estrogen
As an added bonus, since D-AA is a naturally occurring non-essential amino acid, your body is already prepared to control and manage both D-AA levels and its effects on your hormones. Studies have shown that while D-AA may significantly increase testosterone and growth hormone levels for several weeks at a time (we recommend cycling 2 weeks on/2 weeks off), the subsequent increases in estrogen and other undesirable hormones are virtually nonexistent.2,4,5
What does this mean for you?
Plain and simple – unlike many other testosterone supplements – taking D-AA may results in greater testosterone production without the lopsided effect of unbalancing your hormone system and compromising your long-term health.
With more free-testosterone in your bloodstream, you’re likely to have:
- Increased energy and strength*4
- Boosted muscle growth and repair rates*4
- Improved endurance and stamina*4
- Enhanced libido and fat loss*4
In short, D-Aspartic Acid may be one of the best ways to breakthrough strength and performance plateaus by boosting your testosterone and growth hormone levels for short periods without the worry or undesired effects of estrogen.
