Any standard method to verify Serostim? Bar code or something? I have two kits. One was sent to me from the number one source at the time. One I bought on the streets here. There's a pretty big after hours scene here with a lot of sick tweekers so the kits a pretty available. Both sets look exactly the same. Only difference I see is the hologram, both look official, and the markings. The sources was blank. No lot number or expiration. The one I bought here had the stamp as well as the tears where the rx was attached. Any sero experts out there? I'll try to post pics tonight.
