On the GABA for almost a month now, while cutting cheeses and pork products and the like from my diet (for fatloss and high cholesterol). I've slept better, but am also using ZMA again; also slept well without the ZMA. On the downside, I lost an inch off my gut, but also about 1/4" from arms, and 1/2" from chest. Getting old sux.
My research has led me to amino supplementation, since I'm not really getting much from the GABA myself, and others have not gained on it. The regimen (stack) I'm looking at is basically :
Ornithine in the form of OKG at 6g. / day
L-Arginine at 6g. / day
L-Leucine at 3g. / day
and possible L-Glycine at 7g. / day.
The Orni/Argi combo from a lifting team I know here who actually experimented with it up to 22g. / day...resulting in some gout-like side effects from overdosing. But their GH went up significantly. Lab tests done on athletes had GH increases with doses as low as 1-2 grams, as shown below.
The Leucine I added to the stack to counter the possible effects of herpes replication by the arginine, something it's known for. The Glycine is another one tested with athletes and proved to assist workouts. I copied this:
Amino Acids Study Results (from this site
http://www.vrp.com/art/507.asp
Intravenous Ornithine Produces a five-fold increase in serum growth hormone in humans.
Ornithine Increased serum growth hormone in bodybuilders, up to four times the baseline level.
Arginine 250 mg/kg/day of oral arginine aspartate given to five healthy subjects for seven days caused a 60% rise in GH during slow wave sleep compared to the control period.
Arginine and Ornithine In a double-blind study, adult males participating in a 5-week progressive strength-training program who consumed 2 grams of L- arginine and 1 gram of L-ornithine experienced significantly higher total strength and lean body mass scores and excreted less urinary hydroxyproline (marker of catabolism) than placebo-treated subjects.
Best buy?
Ornithine Alpha-ketoglutarate (OKG)
Significantly increased IGF-1 and growth hormone levels in trauma patients. In healthy subject, OKG increased tissue levels of growth- hormone-releasing glutamine.
A maybe.
Arginine and lysine 1200 milligrams of arginine pyroglutamate combined with L-lysine hydrochloride significantly elevated biologically active growth hormone from two to eight times the baseline value in 15 healthy male subjects aged 15 to 20 years old. Arginine and lysine 1,500 mg arginine and 1,500 mg lysine increased GH in young men only during resting conditions.
Not after exersize.
Glycine In 19 normal, non-obese subjects, 6.75 grams of glycine increased growth hormone levels up to 300 to 400 percent that of baseline.
Glycine and L-arginine
Increased the subjects mean resistance to fatigue up to 28% over the controls during acute exhaustive high-intensity anaerobic isokinetic exercise and produced an overall gain in total muscle work of 10.5% more than controls.
OTHER best buy?
Gamma Aminobutyric Acid (GABA)
A single oral dose of 5 grams of GABA administered to 19 subjects significantly elevated plasma growth hormone levels compared to placebo-treated controls.
Not doing anything yet...
Glutamine Two grams of oral glutamine resulted in elevated plasma growth hormone in 8 of 9 subjects tested.
Always a goodie.
