What Is Alpha GPC?
Alpha-GPC is a natural choline source also known as alpha-glycerylphosphorylcholine and choline alfoscerate. Alpha GPC is one of if not the most efficient choline source supplement with superior bio availability.  

Alpha GPC Benefits & Uses May Include:

  • Supports Enhanced Cognitive Function
  • Supports Enhanced Memory Recall
  • Supports Improved Powder Output

How Does Alpha GPC Work?
Alpha GPC is able to more readily cross the blood-brain barrier and is a biosynthetic precursor of acetyl-choline neurotransmitter. Alpha-GPC is considered to be the best source of Choline as a nootropic and it functions by increasing the amount of available Choline, which naturally converts to and influences the production of Acetyl-choline. Acetylcholine is a powerful neurotransmitter that is responsible for learning, memory, and other important cognitive functions. Recent studies suggest that supplement of Alpha GPC may improve athletic performance, specifically power output during exercise.

    Best Deal Anywhere! Seriously!!

    The product mixes well in water and has noticeable effects affirming its authenticity. I believe my memory retention improves as a result, and my sleep quality undoubtedly does improve. Try it for yourself! If you find Alpha GPC for a lesser price than Hard Rhino, there is a reasonable chance it is fake. I know from experience, so you should stick with companies who have their products lab tested.

    Hard Rhino's Alpha GPC 50% is the highest quality Choline source that I have came across. I have noticed that my memory, ability to think critically, and creativity has increased. It is also worth noting that I stack this product with fish oil and piracetam. Overall, this is a great quality product, and I recommend to anyone who is interested in enhancing their overall cognition.
