arginine and GH response

Growth hormone, arginine and exercise.

PURPOSE OF REVIEW: To describe the effect of an acute bout of exercise on growth hormone responses and to discuss the effect of L-arginine supplementation on growth hormone responses. RECENT FINDINGS: Recent studies have shown that resting growth hormone responses increase with oral ingestion of L-arginine and the dose range is 5-9 g of arginine. Within this range there is a dose-dependent increase and higher doses are not well tolerated. Most studies using oral arginine have shown that arginine alone increases the resting growth hormone levels at least 100%, while exercise can increase growth hormone levels by 300-500%. The combination of oral arginine plus exercise attenuates the growth hormone response, however, and only increases growth hormone levels by around 200% compared to resting levels. SUMMARY: Exercise is a very potent stimulator of growth hormone release and there is considerable research documenting the dramatic growth hormone rise. 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. This diminished response is seen in both in both younger and older individuals.

Ok so we have learnt from this that arginine combined with exercise will be less effective in producing growth hormone compared to exercise alone. So this means exercise without the use of arginine is better and then once exercise is completed when your resting arginine is better used then as it will have an effect on resting growth hormone levels compared to not taking anything.

So you should exercise wait about 1-2 hours then consume arginine, or take arginine before bed at a dose of around 5-7g.

Oral arginine attenuates the growth hormone response to resistance exercise

This study investigated the combined effect of resistance exercise and arginine ingestion on spontaneous growth hormone (GH) release. Eight healthy male subjects were studied randomly on four separate occasions [placebo, arginine (Arg), placebo + exercise (Ex), arginine + exercise (Arg+Ex)]. Subjects had blood sampled every 10 min for 3.5 h. After baseline sampling (30 min), subjects ingested a 7-g dose of arginine or placebo (blinded, randomly assigned). On the exercise days, the subject performed 3 sets of 9 exercises, 10 repetitions at 80% one repetition maximum. Resting GH concentrations were similar on each study day. Integrated GH area under the curve was significantly higher on the Ex day (508.7 ? 169.6 min?ng/ml; P < 0.05) than on any of the other study days. Arg+Ex (260.5 ? 76.8 min?ng/ml) resulted in a greater response than the placebo day but not significantly greater than the Arg day. The GH half-life and half duration were not influenced by the stimulus administered. The GH secretory burst mass was larger, but not significantly, on the Arg, Ex, and Arg+Ex day than the placebo day. Endogenous GH production rate (Ex > Arg+Ex > Arg > placebo) was greater on the Ex and Arg+Ex day than on the placebo day (P < 0.05) but there were no differences between the Ex and Arg+Ex day. Oral arginine alone (7 g) stimulated GH release, but a greater GH response was seen with exercise alone. The combined effect of arginine before exercise attenuates the GH response. Autonegative feedback possibly causes a refractory period such that when the two stimuli are presented there will be suppression of the somatotrope.

i recommend using Agrinine when close to comp b4 bed with GABA too. it work extremely well with girls training or with athlets who used HGH /IGF as a part of PCT when they go off every thing, any one using HGH for more than 4 months str8 should consider it IMO. while naturals should add it into there stack if they using test booster, that will b next to jump into.
