Basically what my friend told me was the effect he had.
Isn't Aspartic Acid the harmful product of Aspartame after digestion?
I'm just looking for a product that will allow me to produce better results alongside proper nutrition and supplements (multivitamin, B complex, protein powder, creatine). Perhaps something that will also increase my motivation and energy levels. |
Aspartic acid's L(evo)rotation is metabolized in proteins and the D(extro)rotation is used as a neurotransmitter. Also, the D-isomer has shown to improve good ole gonadotropin (GnRH). It also enhances growth hormone (GH) and luteinizing hormone (LH), which are released from the pituitary gland. Recall:

Now LH production is influenced by gonadotropin-releasing hormone or GnRH. GnRH stimulates the front part of the pituitary gland to secrete LH and another hormone called FSH (follicle stimulating hormone.) The LH is the primary stimulus of testosterone secretion. The FSH is what stimulates the beginning formation of our baby makers/sperm.
So since the testosterone secretion is stimulated by LH from the pituitary gland, the quantity of testosterone secreted increases in direct proportion to the amount of LH available. What does it all mean Bazil? There’s a balance to be kept between LH and testosterone. Also, there’s a feedback if there’s too much testosterone in the body. This will cause the pituitary to say, “chill out on the production of LH!” STAY WITH ME!!! Whenever the causation of said increases of testosterone ceases then the front part of the pituitary will need to be turned back on to produce appropriate amounts of LH to form testosterone. This shut down usually is caused by too much testosterone, which has a negative affect on the hypothalamus’s secretion of our friend GnRH. This in turn causes decreases in secretion of both LH and FSH…in the front part of the pituitary gland. This DECREASE in LH decreased the secretion of testosterone in the testes. Someone wisely mentioned last week about the negative feedback loop involved in this matter. To take it a little deeper, whenever the secretion of testosterone becomes too great, the negative feedback effect occurs via the hypothalamus and front pituitary gland and this reduces the testosterone secretion back toward normal operating levels. Oppositely, too little testosterone allows the hypothalamus to secrete huge amount of GnRH, which increases the front pituitary’s LH and FSH secretion and as a result increases the testicular testosterone secretion.

So the D-aspartic acid not only seems to directly increase testicular production of testosterone, but also the secretion of it. Again, I'm guessing it does this by affecting/increasing (LH) and (GH) levels.
I may pull out some biochem- and/or endocrin- books to see if I can find anything else regarding it's mechanism(s) of action.
