Here’s a stack that will work with the testosterone stack we put together for you last month. This one boosts levels of growth hormone, an anabolic hormone that enhances muscle growth and fat loss. Maximizing both testosterone and GH is the best way to stay anabolic. The critical times to boost GH levels are during workouts and while you sleep.
This amino acid has a host of bodybuilding benefits, with just one of those being an effective GH booster. Louisiana State University (Shreveport) researchers found that supplementing with glutamine increased GH levels in as little as 90 minutes after subjects ingested it. The scientists speculated that one way glutamine likely increases GH release is through its ability to stimulate arginine production in the kidneys. Arginine enhances GH release by blunting a hormone that normally would inhibit its release. Another possible way that glutamine works on GH is through its conversion to glutamate, a potent stimulator of GH.
Gamma-aminobutyric acid is actually an amino acid that works as a neurotransmitter in the body. It has numerous positive effects on the nervous system, such as enhancing the body’s sleeping cycle when taken at night. But GABA also stimulates the release of GH. This has been shown in several investigations, with the most recent being a 2008 study from Shenandoah University (Winchester, Virginia). The researchers reported in the journal Medicine & Science in Sports & Exercise that weight-trained men who took 3 g of GABA before working out or just resting increased GH levels by about 200% after the workout and about 400% when at rest.
Alpha-glycerylphos-phorylcholine is derived from soy lecithin and is actually a source of choline. It enhances mental function by increasing acetylcholine production, and it stimulates the release of growth-hormone-releasing hormone, a hormone that does as its name implies — boosts GH release.
STACK THEM LIKE THIS
Take 5-10 g of glutamine, 3-5 g of GABA and 100-500 mg of alpha-GPC with your preworkout shake and again before bed.
GH STACKING SYLLABUS*
