Ingredients List and Description:

D-Aspartic Acid:So how does this naturally occurring amino acid work inside our bodies? Let's take a look!
Laying the Building Blocks for More Testosterone.

Evidence suggests that D-Aspartic acid increases cAMP in the testes, and cGMP in the pituitary. Both cAMP and cGMP act as secondary messengers. In the pituitary, cGMP influences luteinizing hormone production, and more cGMP is believed to lead to more LH. LH is important because it is the hormone that travels from the pituitary down to the leydig cells of the testes. Inside the leydig cells it signals testosterone production. Enter cAMP.

cAMP acts as a secondary messenger that increases StAR expression. StAR is a carrier protein that helps bring cholesterol, the building block of testosterone, into the testosterone manufacturing power plant of the leydig cells. Thus, more cAMP is believed to lead to more testosterone production, as is seen in the human trials performed on D-Aspartic acid.

D-Aspartic acid may also increase human growth hormone output. When using D-Aspartic acid, animal studies reveal high concentrations of endogenous NMDA (N-methyl-d-aspartic acid) in the brain. D-Aspartic acid is converted into NMDA which enhances the release of Growth Hormone Release Hormone (GHRH) and Gonadotropin-releasing hormone (GnRH), also known as luteinizing-hormone releasing hormone (LHRH). GHRH does exactly what is sounds like, releasing growth hormone into the body. However, while human trials specifically measuring for this outcome are needed, it is certainly an interesting possibility to consider and welcome effect if D-Aspartic acid does increase concentrations of human growth hormone. The benefits of human growth hormone are certainly very advantageous to athletes and bodybuilders.

Tongkat Ali(Eurycoma Longjifolia) 200:1 Extract: Most companies are using a 20:1 50:1 or at most a 100:1 extract of this herb. At 50:1 it is slightly effective at inhibiting testosterone from aromatizing into estrogen,at 100:1 it is  effective. At 200:1 extract the costs goes through the roof and most companies do not want to deal with this over head so they risk quality and potency. Because they have quotas to meet and they prefer to spend ingredient money on marketing campaigns paying pro Athletes for sponsorships that do not even really use the products just cash the checks. We do not cut any corners at XPS because unlike other companies we do not spend our profits on marketing but spend it in product and ingredient purity and quality and research. We bring you a 200:1 Extremely potent Tongkat Ali extract not used by any other manufaturers.

Tribulus Terrestris 90% Saponins: Tribulus terrestris is a plant that grows in tropical climates.  The part of the plant from which there is the most interest lies in the root.  This plant has been used around the world for a variety of ailments.  It has been used as an herbal supplement diuretic, antiseptic, anti-inflammatory, and as a mood enhancing tonic.

The most noted benefits of tribulus terrestris is it's use in treating sexual deficiencies.  It has been used in  Asia and Bulgaria for years to treat libido and infertility problems.  Tribulus terrestris is a non-hormonal herb that restores and improves libido in men as well as improving and prolonging (no pun intended) the duration of erections.  Tribulus terrestris increases the number of sperm and the mobility of them.

The reasons for all of this are that somehow tribulus terrestris increases testosterone levels by increasing luteininzing hormone (LH) levels.  LH is the hormone that signals the body to start making natural testosterone.  There is a study involving individuals taking 750 mg per day of tribulus terrestris.  It showed that LH increased from 14.38 ml/U/ml to 24.75 ml/U/ml (which is a 72% increase in LH).  Free testosterone went from 60 ng/dl to 84.5 ng/dl (which is an increase of 41%).  These increases in testosterone are why bodybuilders have interest in using this supplement.  They have been experiencing increases in muscle size, stamina, and strength.
