Key MethodA study was carried out in 15 male volunteers to evaluate qualitatively the secretion of growth factors following stimulation by oral amino acids. The results showed that oral administration of a combination of two amino acids (1200 mg 1-lysine plus 1200 mg 1-arginine) provoked a release of pituitary somatotropin and insulin. This phenomenon was reproducible and the growth hormone secreted in response to this stimulation had biological activity (as demonstrated by a radioreceptor assay and…

Low-dose amino acid supplementation: no effects on serum human growth hormone and insulin in male weightlifters.

The ergogenic value of low-dose oral amino acid supplementation in increasing hGH or insulin secretion seems questionable.

Acute amino acids supplementation enhances pituitary responsiveness in athletes.

The amino acid mixture used enhanced the ACTH, LH, and FSH response to CRH + GnRH and significantly higher in AS group both as absolute values and area under curve (AUC) values than in P1-AS group.

A Pilot Study in Normal Volunteers of the Effects of the Renuva™ System on Growth Hormone and Insulin-Dependent Growth Factor-1

The Renuva™ System increases GH and IGF-1 and both the Generator Drink and the Infuser Spray appear to contribute to the increase in IGF- 1.

Neuroendocrine control of growth hormone secretion.

The secretion of growth hormone (GH) is regulated through a complex neuroendocrine control system, especially by the functional interplay of two hypothalamic hypophysiotropic hormones, GH-releasing

Increased Human Growth Hormone After Oral Consumption of an Amino Acid Supplement: Results of a Randomized, Placebo-Controlled, Double-Blind, Crossover Study in Healthy Subjects.

Results show that a single dose of the oral amino acid supplement was sufficient to significantly increase hGH levels in healthy adult men and women.

Growth hormone, arginine and exercise

At rest oral L-arginine ingestion will enhance the growth hormone response and the combination of arginine plus exercise increases growth hormone, but this increase may be less than seen with exercise alone.

Tissue-specific regulation of potassium homeostasis by high doses of cationic amino acids

The analyses of the expression of cationic amino acid transporters (CAT) suggest that the CAT-2 transporter may be implicated in the potassium/cationic amino acids interchange in liver and pancreas.




Plasma levels of growth hormone have been shown to rise during or following spontaneous and experimentally induced hypoglycemia, prolonged fasting, vigorous muscular exercise, surgical stress, inhibition of glucose utilization by 2-desoxy-glucose, and a rapid and significant fall in blood glucose levels.

Assessment of growth hormone reserve: comparison of intravenous arginina and subcutaneous glucagon stimulation tests.

The data shows that arginine is a consistent and potent stimulus for growth hormone release, and is superior to glucagon as a test for growth hormones reserve.

Radioreceptor-inactive growth hormone associated with stimulated secretion in normal subjects.

No significant measurement discrepancy was found in basal samples from normal subjects, in contrast to previous findings in acromegalics, and RRA methodology has now been adapted to allow detection of hGH at normal circulating levels.

Effect of somatostatin on thyrotropin, prolactin, growth hormone and insulin responses to thyrotropin releasing hormone and arginine in healthy, hypothyroid and acromegalic subjects.

Preliminary data indicate increased sensitivity of the prolactin-secreting cells to somatostatin in hypothyroidism and suggest that decreased responsiveness of the somatotrophs to som atostatin could play a role in the pathogenesis of acromegaly.

Determination of the optimum dietary proportions of lysine and tryptophan for growing rats based on growth, food intake and plasma metabolites.

The optimum lysine:tryptophan ratio was between 4 and 5 for the rapidly growing 3- to 6-week old rat, and a tryptophan requirement of approximately 0.15% whenLysine was adequate.
