GABA (Gamma-Aminobutyric Acid)
Also Known As: Brain Relaxant, HGH Booster, Inhibitory Neurotransmitter
Compound Type: Neurotransmitter / Growth Hormone Secretagogue
GABA is the primary “inhibitory” neurotransmitter in the human brain. Think of it as the body’s natural braking system—it calms over-firing nerves, reduces anxiety, and promotes deep relaxation.
For Penis Enlargement, however, we aren’t taking it just to chill out. We are taking it because clinical research has identified GABA as a potent trigger for the pituitary gland to release massive amounts of Human Growth Hormone (HGH).
How Does GABA Affect Penis Size?
GABA works through two pathways: Hormonal Optimization (spiking HGH levels) and Neurological Recovery (reducing the stress hormones that shrink the penis).
The Science: The “400% HGH Spike”
1. The Powers Study (HGH):
A landmark study by Powers et al. (2008) found that oral administration of 3g of GABA increased immunoreactive Growth Hormone (irGH) by 400% at rest. HGH is the “master hormone” responsible for cell division and tissue repair. If you are doing PE exercises (causing micro-tears), HGH is the fuel that rebuilds that tissue larger.
2. Cortisol Antagonist:
Cortisol is catabolic (it breaks down muscle and tissue) and causes vasoconstriction (shrinkage). GABA directly opposes cortisol. By keeping stress hormones low, you maintain a “Pro-Anabolic” state where your body focuses on building tissue rather than fighting stress.
3. Deep Sleep (REM):
The majority of natural HGH is released during deep sleep. GABA improves sleep latency and quality, ensuring you get the maximum “repair time” every night.
✔ The Verdict: RECOVERY ESSENTIAL
The “Growth” Trigger. We highly recommend GABA for anyone performing physical PE exercises (Jelqing, Pumping, Extenders). While it won’t give you an erection on its own, it provides the HGH spike needed to turn your hard work into permanent tissue gains.
1g – 3g
Before Bed or Workout
“Tingle” sensation is normal
Safety Profile & Side Effects
- The “GABA Tingle”: High doses (3g) often cause a harmless tingling sensation (paresthesia) in the face and neck. It fades in 20 mins.
- Shortness of breath (at very high doses).
- Drowsiness.
- Alcohol: Do not mix. GABA potentiates the sedative effects of alcohol.
- Benzodiazepines (Xanax/Valium).
