Why Alpha-GPC 50%?
Pure Alpha-GPC is very hygroscopic and absorbs moisture from the air, turning pure alpha-GPC into a paste if it sits long enough. This is not ideal for supplementation, so we provide a 50% powder.
What is Alpha-GPC?
Alpha GPC is a cholinergic substance used for its cognitive enhancing abilities; there is also evidence that it can reduce the rate of age related memory loss. Alpha GPC also has atheltic implications as it can enhance the production of growth hormones as well as muscle strength.
Nutritionally supporting vibrant mental health can be difficult through food alone. The modern diet does not always provide your brain with all of the nutrients it needs. That being said, some common Alpha GPC food sources include milk, soy, and eggs . However, supplementation is a much more direct method of attaining Alpha GPC. Plus, Alpha GPC is the most efficient cholinergic supplement on the market.
Due to the water solubility of Alpha GPC and its quick absorption, this form of choline is quickly becoming a popular addition to many nootropic stacks, and it is being used as a nootropic in its own right.
Users most often take Alpha GPC for the improvement of general cognition, memory, thinking, and learning. Alpha GPC has been repeatedly shown to increase attention and certain aspects of memory.  
Not only does Alpha GPC provide choline, it bonds with the omega-3 fatty acid docosahexaenoic acid (DHA) through an enzyme process that builds new membranes that promote nerve cell expansion.
This nerve expanding property of Alpha GPC is not its only claim to fame, because Alpha GPC also supports high choline levels. This helps in the creation of acetylcholine which is one of the most important neurotransmitters when it comes to thinking, memory, and learning.
High acetylcholine levels created by Alpha GPC supplementation can also benefit people who are seeking to enhance brain-muscle integration. Alpha GPC has also shown to improve brain functioning in young people.
Bodybuilders and fitness enthusiasts can also benefit from Alpha GPC. One study found that taking Alpha GPC before a power test resulted in a 14% increase in power output . Alpha GPC can also stimulate growth hormones .
Finding the right Alpha GPA dosage can be a little tricky. Individuals should start with a dosage of 300mg. Once you learn how you respond to Alpha GPC you can increase up to 600mg.

This is a great cognitive and memory enhancer and worthy of anyone shooting for that ultimate NZT stack.
The second batch I received was totally different, which is already a pretty bad sign in a supplement. Not creamy, but instead sandy feeling, not completely water soluble. It has a bad taste, and I have to take higher doses to notice the effects. The COA says it all, now that I've finally looked at it closely (my bad for not looking in the first place). The product claims to be "pure bulk powder", but "pure" is not quite the right word for a product that is 52% Alpha GPC, and 48% other (mostly dicalcium phosphate dihydrate, which is a calcium supplement mostly used in processed/pet foods). There's also 0.5-1.5% silicon dioxide...yep...the product is about 1% sand. Adding calcium is probably not hazardous (though theoretically does increase the possibility of excitotoxicity from some ampakines, like aniracetam or sunifiram), but it's doubling the shipping weight and adding no value. Also, the supplement information label is still incorrect after several months of my mentioning that the label says that taking 500mg of the product will provide 150mg of alpha GPC (it should say ~250mg of alpha GPC).
I generally like this site, but this particular product is not up to the standard of quality I see elsewhere. Please fix it. Silicon Dioxide and Dicalcium Phosphate are not water soluble like Alpha GPC, so you or your supplier should easily be able to purify this and truly offer "pure bulk powder". Get your supplier to do it, so you can halve your shipping costs?...
