BulkSupplements.com Alpha GPC Powder - Choline Supplements, Alpha GPC 300mg - Unflavored & Gluten Free, 600mg per Serving, 500g (1.1 lbs) (Pack of 1)

Why did you pick this product vs others?:I picked this product over others because of the low cost and effectiveness of the supplement. It part of my morning stack that help to turn my lights on for the day's work

I really like this brand and version of Alpha-GPC. It has great quality, helps cognitive functions and energy levels. It dissolves perfectly in any drink or smoothie. I would recommend this to anyone looking to add this Nootropic to your daily stack.

There’s plenty of product here to last you a long time. Get a scale and this is the only way to go. Much cheaper than buying it in capsules.

I was looking for a cost-effective way to add Alpha-GPC to my supplement regimen and BulkSupplements.com's Alpha-GPC Powder fit the bill. The powder itself is very fine and mixes well into drinks or smoothies. Having a larger quantity is great because I can customize my dosage and it will last a long time. The resealable pouch keeps things fresh, and the included scoop is a convenient way to measure out the powder. Overall, I'm happy with this purchase for my needs.

The product arrived a week earlier than expect and seems to be good quality. I don't have another product to compare it to, but it seems to be exactly what is on the label.As others have stated, this does not completely dissolve in water. Alpha-GPC is soluble in water, but this product is only 50% Alpha-GPC. The gritty texture in water is likely the ~100mg per serving of dihydrate calcium phosphate, which is insoluble. I'm not sure exactly what this addition is for, but it is apparently safe to consume.If the gritty texture really bothers you, I would suggest a 100% Alpha-GPC product, but even at half the weight this is still an excellent deal. The package doesn't like to seal well, but I like to transfer bulk supplements to glass jars for storage anyway.

Great product. Not cakey or chunky. No flavor. Dissolves nicely in water.

Alpha GPC is great for concentration. This product is great quality at a great price.

Powder does not dissolve completely in any liquid for any amount of time, no blender or blender bottle will make this powder dissolve. It clumps up and makes an odd reaction to any liquid it's poured into, not sure if I got a bad batch but this product seems unsafe to consume. Unfortunately I will be tossing this and taking a loss. I have to try different brand.
