I never experienced any problems with respect to payment as well as quick and convenient delivery. So far, there was never the chance to ask for refund as any order was properly handled and discretely delivered. According to my experience and that of my friends the prices are justified and equilibrated according to the market level. The products do their job and seem to have the concentration that is stated on the Certificates of Analysis as provided on the website. The vials are packed in a professional manner. In this context it is important to mention that I never experienced any problems in terms of sterility. In summary, I can stress that Steroid-UK products are off excellent quality. Dr. Debil
