Bests & Worsts Reviews from Amazon

I ordered this Spirulina powder from Bulk Supplements and within a few days of receiving it, someone here prompted me to ask about its origin. I realized I should have inquired more about this product and where it came from, especially since there are some very BAD Spirulina products out there with dangerous additives and toxins (including but not limited to China). I wrote to the company and asked them where it was harvested from and they gave me a vague answer. When I inquired further and asked them to send me a COA (certificate of analysis, which would provide nutritional ingredients or additives during manufacture, as well as origin country) they responded with a BLOCKED out COA. Both the top and bottom of the form was covered up so that I had no way of knowing what product had been tested, when or where. This is HIGHLY SUSPICIOUS. I wrote back and complained of this, asked for a COMPLETE COA, and they finally replied back (almost two weeks later). They offered a full refund, and verified this product is made in China. However, they never explained why the covered up COA and even responded as if this was perfectly normal. I have yet to receive the full, uncovered COA from them and doubt I ever will. Strange and very scary indeed. I DO NOT RECOMMEND THIS PRODUCT nor ANY PRODUCT FROM THIS COMPANY. If your health and safety are a concern, then I would steer clear of them or any products they sell. If I hear otherwise or receive a complete COA, I will certainly update my review. BTW, BulkSupplements.com promised me a FREE product if I provided a review on Amazon. Something tells me I won't be seeing that freebie now! It would not matter as I would not be ingesting anything from Bulk Supplements until they come clean and clear with me. I was told that a complete COA for Spirulina or any supplement, would be easily acquired from a legitimate company. Therefore, you can understand why my assessment of them is not good. I am an even-keeled person with no desire to hurt anyone's reputation, but when I inquire about safety and receive a document with the vital identifying information blocked or whited out, this is a red flag. My trust in this company has flown out the window. I also do not want anyone else to risk their health, in case this red flag is accurate. UPDATE: Several months later, Bulk Supplements sent me a complete COA for their spirulina powder with sincere apologies about their "former" employee's mishandling of my order. They still have not reimbursed my money and the COA confirms that their product is harvested and tested in China. I have already found a more reliable source of quality Spirulina (Spirulina Pacifica) made by Nutrex in Hawaii.
