PRIMAFORCE D-ASPARTIC ACID (DAA)
What is D-Aspartic Acid?
D-Aspartic Acid (DAA) is the newest natural testosterone booster on the market. DAA is the D-form of the amino acid aspartic acid. The body can produce DAA from the nonessential amino acid L-aspartic acid (the dietary form of aspartic acid). D-form amino acids, such as DAA, are found in higher concentrations in specific tissues in the body. For example, higher concentrations of DAA are found in the testes, pituitary gland, and hypothalamus (D'Aniello & Di Fiore 2000) all of which are areas involved in hormone production.
What Does D-Aspartic Acid Do?
One big difference between DAA and other natural testosterone booster is there is actually scientific data in HUMANS showing it to effectively increase testosterone levels. A study by Topo et al. showed that supplementing with 3 grams of DAA increased circulating luteinizing hormone (LH) levels by 33% and testosterone levels by 42% in men aged 27-37 years old (Topo & Soricelli 2009). Note that this increase in testosterone was in healthy men with normal testosterone function, not rats or hypogonadal men! Note the increase in testosterone by 42% was after only 12 days of supplementation and testosterone levels returned to baseline three days after stopping DAA.
Due to DAA’s action at the pituitary gland it should also increase growth hormone (GH) levels, though studies have not yet measured DAA’s impact on GH levels. Studies have not yet been done in women, but there is one study done in female lizards that showed DAA supplementation to have no effect on testosterone levels but it did increase estrogen levels (Assisi & Botte 2001). Therefore at this time it appears only men should supplement with DAA.
Further studies need to be done to examine DAA’s affects on estrogen and prolactin levels, but at this time there are no side effects reported with DAA use. DAA is a natural amino acid found in our food supply and produced by the body making it a great tool to naturally increase healthy males testosterone production.
Recommended Dosage
The dosage used in the study showing DAA to increase testosterone levels was 3 gram taken in the morning. However, a five day loading phase of 3g morning and 3g evening would be recommended.

TESTIMONIALS
Hi Everyone just wanting to tell everyone about the benefits and the experience i've had using Primaforce D Aspartic Acid im a Natural teen age bodybuilder 19 years of age i had my testosterone levels checked at february last year they came back with a level of 6.4 then to see if it wasnt a a fluke i went back for a 2nd test in september they came back even lower ! at 4.3 i couldn't believe they were that low in my age group they should be between - 8.0 - 26.0 so i had a look around for natural testosterone boosters. the first brand i had a look for was scivation a nd primaforce, they had the D aspartic acid - i asked my coach Layne Norton if this might help if i took it he said go for it there has been scientific studies showing that the D aspartic acid does increase natural testosterone getting the allowance of layne and knowing it had research behind it i gave it a shot for 3 weeks on the 2nd week i got my testosterone levels checked in december to see if it had increased and what do you know ! my levels had tripled ! from the previous test the results came back with 12.3 , having being worries about my levels i know do not have to worry as the D aspartic acid has proven to me its benefits ! I will be using the D aspartic acid as one of my staple supplements along with scivations xtend my favourite supplement buy far + prima force creaform and prima force beta alanine ! i will be using the D aspartic acid cycling it with 6 weeks on 6 weeks of. scivation/primaforce is my #1 brand as the purity and quality are unmatchable in the supplement world and the science behind there supplements make them my #1 brand
Thanks Marc and Scivation Team !
