@kRazy-pep it comes down to your own risk tolerance. There are bunch of really good vendors on here. I can only comment on the ones I have tried and researched, and also my own mistakes. Most of us have been burned. Me more than once. You can't go wrong with
EZ Peptides or
Nexaph. I really like
Glacier Aminos, Mile High, Southern, and others, but when I see Kovera as the lab, I have some concerns which may or may not be real concerns. All of those vendors do full panel testing, which includes endotoxins. If you see Janoshik, Trust Point, or Vantage as the lab, that, for me, is the gold standard as we sit here today, so keep that in mind. Just my opinion; others may disagree. Hope this helps
