Alpha-GPC: The Choline Compound With Real Performance Data
Alpha-GPC (alpha-glycerylphosphorylcholine) is one of the few nootropics with hard human RCT data on both cognition and athletic output. It rapidly crosses the blood-brain barrier and delivers choline for acetylcholine synthesis β the neurotransmitter behind focus, muscle contraction, and reaction speed.
What the Research Shows
- Vertical jump: 600 mg pre-training increased peak isometric force and vertical jump vs. placebo (J Int Soc Sports Nutr, 2015).
- Growth hormone: Single doses of 600β1,000 mg triple resting GH within 60β120 minutes.
- Cognitive processing: Improved attention, reaction time, and memory in both healthy adults and mild cognitive impairment.
- Power output: Multiple trials show improved lower-body power and delayed neuromuscular fatigue.
How to Use It
- Training days: 300β600 mg, 30β45 min pre-workout. Stacks well with caffeine and creatine.
- Cognitive-demand days: 300 mg with morning coffee for meetings, exams, or long drives.
- Recovery from concussion or neuromuscular injury: Some clinical protocols use 600β1,200 mg/day (work with a clinician).

Frequently Asked Questions
- What's the effective dose of Alpha-GPC?
- 300β600 mg, taken 30β45 minutes before training or a high-focus task. The 600 mg dose is the most commonly studied for both cognitive and performance outcomes.
- Can I take it every day?
- Yes. Alpha-GPC has an excellent safety profile in trials up to 1,200 mg/day for 6 months. Cycle is not required, though many users pulse it only on training or high-demand days.
- Will it show up on a drug test?
- No. Alpha-GPC is not on any banned-substance list. If you're drug-tested, choose an NSF Certified for Sport version like Momentous.
