Got my second order from Certified Peptides. I'm very happy with both orders, high quality peptides at a great price! When you order from them you immediately get a email..everytime you get complete information on every peptide they sell. How to reconstitute, what to use and dosage, plus everything you need to know about any peptide…. have a question, just ask and several people will be trying to help. I haven't seen customer service like this in YEARS!
