Factory Supply Pure Poly Glutamic Acid Powder PGA Poly-L-Glutamic Acid Powder
Hi, I would like to purchase some gamma poly glutamic acid for research. Our lab has been using the gPGA from your company for years, so I would like to purchase the exact same product to ensure the reliability of the data. Thanks very much! This is the Batch No. I found on the Al bag in our lab: BL********B.
