D-Aspartic Acid for Luteinizing Hormone and Testosterone

D-Aspartic Acid

While lots of supplements claim to increase testosterone, D-Aspartic Acid is one of the few that delivers on its promise.

Many supplements only increase testosterone in people with hormone problems or old age, but D-Aspartic Acid even works in exercising young males (and to a significant degree, too). Read on for more details.

D-Aspartic Acid → Luteinizing Hormone → Testosterone

Here’s a little background for you: Leydig cells, which reside in the testicles, produce natural androgenic steroids (testosterone, androstenedione and dehydroepiandrosterone DHEA) when in the presence of luteinizing hormone. Luteinizing hormone is produced by the pituitary gland next to the brain. Supplementing with D-Aspartic Acid can increase luteinizing hormone, resulting in higher testosterone production in the testicles.

The following study clarifies just how effective supplementing with D-Aspartic Acid is on luteinizing hormone and testosterone. Is was done on 23 healthy males between the ages of 27 and 37 and an additional 20 in a placebo group.[1] The experimental group took 3g of D-Aspartic Acid per day for 12 days.

The group who took D-Aspartic Acid increased their Luteinizing Hormone by 7% after 6 days, and 33% after 12 days. 33% after 12 days is a big increase, and it’s higher than that recorded at the 6 day mark, so it’s possible that continued supplementation after 12 days could result in an increase greater than 33%, but that wasn’t tested.

Testosterone was increased by 15% after 6 days and 42% after 12 days. Of the 23 participants, 20 of them (87%) had an increase in testosterone. I expect the ones whose testosterone fell had unhealthy behavior in the testing period like no exercise, lack of sleep, stress or dehydration. The 42% increase includes the people whose testosterone fell, meaning the 20 people whose testosterone increased, actually increased by more than 42%. 87% is a very high success rate, suggesting that you can be confident that D-Aspartic Acid works when taken at 3 grams per day.

Here is the results data including placebo group.

Drug Tests

D-Aspartic Acid is not on the WADA (World Anti-Doping Agency) banned substances list, meaning it’s allowed to be taken by sports people. Injecting 1-androstenedione by comparison, is banned. D-Aspartic Acid can encourage your body to produce more natural androstenedione (which is not banned). So D-Aspartic Acid, while not as effective as injecting steroids (which can increase testosterone by hundreds of percent), it is a safer, cheaper, and legal method of increasing your body’s natural androgenic hormones.


Amazon has an extremely competitive price for D-Aspartic Acid in powder form. At $7.50 for 100 grams (at last check), that is about 50% cheaper than other major suppliers.


As with any product that increases testosterone, you may see elevated estrogen and related side effects (since a part of the additional testosterone will convert to estrogen). You would be wise to research the side effects further, so you can potentially recognize and treat them, or avoid them.

Daniel has a strong interest in evidence supported fitness training, preparation and supplementation. His goal is to provide clear information that simply works. He's currently 16 kg of muscle above his starting weight (7kg in the past 12 months), and targeting a continued growth rate of 5kg+ per year.
