Manufacturer statement
Bulk’s own Food Safety page says: “All relevant batches of our products are independently tested for pesticides, heavy metals, microbial activity, and other contaminants.” The product page also says the powder is made with hydrolysed collagen and that Bulk’s quality team uses internal and third-party checks, but I did not find an independently verifiable COA or registry entry for this specific collagen product.
