clearly you are the one with the comprehention problem.
i asked you for studies that show equal amounts of phenyalanine when take seperately from other aminos have destinct anti depressant and analgesic effects.
you try to change the subject and act smart by telling me to read about animo acid metabolism 
you have owned yourself you dumb ####.
once again, for your simpleton mind - if you can show me studies that show equal amounts of phenyalanine when take seperately from other aminos have destinct anti depressant and analgesic effects i will admit you have owned me publically on this forum, and say sorry.
if not disappear and never have the cheek to address me again.
i am just angry that i missed this for so long and allowed your feeble ego to grow for a few days by believing you have owned me in any way shape or form. 
sure you fucktard, i can do that quite easily. LOL, first a simple review. This is simply shit i had on my hard-drive, i didnt even have to re search pubmed LOL.

DL-phenylalanine markedly potentiates opiate analgesia - an example of nutrient/pharmaceutical up-regulation of the endogenous analgesia system.Russell AL, McCarty MF.
Brampton Pain Clinic, Bramalea, Ontario, Canada.
In the author's clinical experience, concurrent treatment with DL-phenylalanine (DLPA) often appears to potentiate pain relief and also ease depression in patients receiving opiates for chronic non-malignant pain. An analysis of this phenomenon suggests that it may be mediated, at least in part, by up-regulation of the 'endogenous analgesia system' (EAS), a neural pathway that projects caudally from medullary nuclei to the dorsal horn of the spinal column; when stimulated by chronic pain or therapeutic measures such as opiates or acupuncture, the EAS suppresses activation of second-order pain-receptive neurons in the dorsal horn, and thereby alleviates pain. Since serotonin and enkephalins are key neurotransmitters in the EAS, it is reasonable to predict that measures which promote serotonin activity (such as 5-hydroxytryptophan and serotonin-reuptake inhibitors) as well as enkephalin activity (such as D-phenylalanine, an enkephalinase inhibitor) should potentiate EAS-mediated analgesia - a view consistent with much previous medical research. Comprehensive support of the EAS with well-tolerated nutrients and pharmaceuticals may amplify the analgesic efficacy of chronic opiate therapy, while enabling dosage reductions that minimize opiate side-effects. Analogously, this approach may complement the efficacy of acupuncture and other analgesic measures that activate the EAS. Copyright 2000 Harcourt Publishers Ltd.

DL-phenylalanine versus imipramine: a double-blind controlled study.Beckmann H, Athen D, Olteanu M, Zimmer R.
In a double-blind study, DL-phenylalanine (150--200 mg/24 h) or imipramine (150--200 mg/24 h) was administered to 40 depressed patients (20 patients in each group) for 30 days. Diagnoses were established according to the International Classification of Disease (ICD). The AMP system, the Hamilton Depression Scale and the Bf-S self rating questionnaire (von Zerssen et al., 1974) were used to document psychopathological, neurologic, and somatic changes. Twenty-seven patients (14 on imipramine, 13 on phenylalanine) completed the 30-day trial. No statistical difference could be found between these two drug treatment groups (Student's t-test) using the Hamilton Depression Scale and the Bf-S self rating questionnaire. Ratings for anxiety were significantly lower in the imipramine group on days 10 and 20, but not on day 30; in addition, sleep disturbances were more influenced by imipramine on days 1, 5, and 10, but not on days 20 and 30. Separate analysis of psychopathological syndromes as somatic depressive syndrome and retarded depressive syndrome did not show a group difference (0.05 level of significance using a two-way analysis of variance).
It is concluded that DL-phenylalanine might have substantial antidepresant properties. However, certain methodological considerations still warrant a careful interpretation.1: J Neural Transm. 1977;41(2-3):123-34. Links
Dl-phenylalanine in depressed patients: an open study.Beckmann H, Strauss MA, Ludolph E.
In an open study dl-phenylalanine in doses from 75-200 mg/day was administered to 20 depressed patients for 20 days. Patients were classified according to the International Classification of Diseases (ICD). The AMP system, the Hamilton depression scale and the von Zerssen self rating questionnaire were used for documentation of psychopathological, neurologic and somatic changes. In addition a global clinical impression was agreed upon by experienced psychiatrists. At the end of the trial 12 patients (8 with complete, 4 with good response) could be discharged without any further treatment. 4 patients with partially untypical depressions experienced mild to moderate responses, whereas 4 patients did not respond at all to the phenylalanine administration. Depressive "core symptoms" as depressed mood, retardation and/or agitation were preferentially, anxiety and sleep disturbances moderately and hypochondriasis and compulsiveness were not influenced.
It is concluded that dl-phenylalanine might have substantial antidepressant properties and that further more controlled investigations are warranted.1: Arzneimittelforschung. 1978;28(

Heres an article explaining a study in laymans terms with some stats i have
http://www.patentstorm.us/patents/4730007/description.html"D-phenylalanine, DL-phenylalanine, D-leucine, DL-leucine and hydrocinnamic
acid have been found to possess analgesic and anti-inflammatory activity.
Their analgesic activity is significantly enhanced or potentiated by the
co-administration of a prostaglandin synthetase inhibitor selected from
the group consisting of aspirin or other non-steroidal anti-inflammatory,
anti-pyretic agents such as ibuprofen and the like. See U.S. Pat. No.
4,439,452, issued Mar. 27, 1984 and commonly assigned, copending
applications U.S. Ser. No. 657,681 filed Oct. 4, 1984 and U.S. Ser. No.
657,732, filed Oct. 4, 1984."
"As can be seen from the above data, acetaminophen and D-phenylalanine,
L-phenylalanine and hydrocinnamic acid each exhibit some analgesic
activity at the very low doses used, coadministration of acetaminophen
with either D-phenylalanine, D-leucine or hydrocinnamic acid produced a
significant, synergistic increase in analgesia."
Make a thread saying you are a moron and have been pwnd by me, at least be a man and live up to your statement and do this. thank you
