are they us based or chinese? honestly if you can manufacture 1 peptide, you can manufacture any. a protein synthesizer is a protein synthesizer. Do you know they make the others or is it just listed in their catalog? "legit and reputable" - what makes them legit or reputable? I'm not saying their stuff is necessarily bad, but anyone can put up a website, anyone can make COAs.
What do they show for purity on the CJC?
Shanghia, China based company!
