    AAKG lowers testosterone?


    I have recently purchased a tub of AAKG powder. After the purchase, I have read that AAKG lowers the body's testosterone levels. Is an accurate statement? If it is, i will be returning the AAKG as soon as it arrives. Any help would be greatly appreciated.

    L-Arginine increases prolactin secretion from the pituitary. This can cause lowered testosterone levels.

    I don't know about the alpha-ketoglutarate.

    Prolactin Response to Arginine in Normal Subjects and in Patients with Hyperthyroidism

    T. ONISHI, F. ITOH*, K. MIYAI, K. IZUMI*, K. SHIMA and Y. KUMAHARA
    * The Central Laboratory for Clinical Investigation, Osaka University Hospital, Dojima, Fukushima-ku, Osaka, Japan and Department of Internal Medicine, National Osaka Hospital Higashi-ku, Osaka, Japan

    The effect of arginine on serum prolactin concentrations was studied in 18 normal subjects and in 7 patients with hyperthyroidism. In normal subjects, arginine infusion produced an increase of serum prolactin at least 6 ng/ml from the baseline, and the mean peak level (25.2 3.3 ng/ml, mean SE) was significantly higher than the basal level (8.6 5.2 ng/ml, P < 0.001). There was no significant difference in the peak levels between sexes. Unlike prolactin, concomitant serum thyrotropin levels did not change after the arginine infusion. In hyperthyroid patients, the increment of serum prolactin after arginine infusion at 30 min (3.9 1.5 ng/ml) was significantly lower than that of the normal controls which were matched by age and sex (17.1 4.4 ng/ml, P < 0.05). After treatment when these patients were euthyroid, the increment of prolactin after arginine infusion at 30 min was significantly increased (16.3 4.3 ng/ml, P < 0.05) and had reached the level of the control subjects. These data indicate that the prolactin response to arginine in hyperthyroidism is diminished.

    It’s a form of arginine specifically, two arginine molecules attached to an alpha-ketoglutarate molecule. Arginine is an amino acid and alpha-ketoglutarate is a form of another amino acid (a glutamine precursor), which may have a glutamine-sparing effect in muscle tissue, leading to more available glutamine. It’s believed that this formulation basically improves arginine’s absorption, thereby increasing your nitric-oxide (NO) production even more. As we know, arginine is a precursor of nitric oxide, which is responsible for vasodilation.

    I never heard Arginine lows T but I read about Prolactin
