I love LA Peptides! First, their presentation is top notch. Every vial is in hologram boxes (not bubble wrap) and has a QR code that refers you to COA’s. If a company cares this much about packaging, you can bet they care more than others about purity. Second, I emailed them about a question I had regarding shipping and got a response back promptly. Lastly, I got my package within 2 days of ordering. I can’t recommend LA Peptides enough!
