Alpha-GPC

Alpha-GPC is offered by Shaanxi Jianhe Bio-Technology Co., Ltd. in pharmaceutical grade under in-house standards, available as either a 50% powder or an 85% oil formulation; note the CAS number given in the source listing (563-23-5) does not match Alpha-GPC's standard registry number (28319-77-9), so it should be treated with caution. The supplier does not manufacture it directly, and it is distributed to markets across North America, Europe, Asia, Australasia, the Middle East, and Africa.
