Four stars because lot numbers are not printed on the vials to match with COA’s but I do appreciate their testing practices. What drew me to this retailer is the full testing with a detailed COA including purity, metals , endotoxins, HPLC chromatogram and Mass graphs for transparency. This is not provided by all peptide retailers. Upon arrival, only some COA’s( Reta), can be matched to both the RIVN and testing the lab’s website using the lot number from the vial because not all vials are labeled with a lot number. For example the Selank, Semax, B12, the reconstitution H2O and the PT-141 do not have lot numbers on the actual vials. RIVN provided a fast and thorough response to my inquiries regarding lot numbers, COA’s and other questions. But what would be more reassuring, is providing Lot numbers on the vials and to have a matching photo in the COA with that same label and lot number. My first order shipped on time with an accompanying H2O vial for every vial ordered, a nice perk. Pricing is fair with full testing being performed, provided the vials without lot numbers are the tested lot they claim it is. All credit cards accepted—a plus if collecting points.

Orders were shipped and received quickly, got a really good deal with one of their specials, and the COA's check out. Will definitely purchase from them again, as a matter of fact probably within the next day or so
