I strongly believe that you've contaminated some vials and sent them for testing. Your credibility is 0 and trust me that all sources know you and know about your practices... we've made them aware about the situation and your email address and name are tracked in their database. If you succeed with any other source from now on, just let me know. Stop spamming and scamming sources.
Your perseverance in this situation reveal your true intentions. To force us to play your game - in your imagination - with the cost of our reputation. No, that is not happening.
We are a source with 14+ years experience in this business so imagine that we wouldn't be here if we would have sold products with sterility concerns or any other issues reported.
