We are looking for Propylhexedrine for a research study being conducted comparing the decongestant effects of it compared with other drugs.I would like the product to be at least 99% pure and would like to receive a sample of it before buying a large quantity, although I'm willing to pay for the sample and shipping.I am willing to pay $50 for a 5 gram sample, but would like to receive the sample to inspect before making a larger order. I appreciate those who will help out and look forward to doing business with you.Country:USA
