Rivn has always been a great supplier of my research needs. The materials are great quality and purity. Pricing is very good compared to many other sites. What made them have 5 stars though. I had a shipment issue with one order. Which Ive ordered many times with no issues at all. This one time though was handled great. The owner while he was on vacation handled my issue and texted and called me directly. He got my pictures and without any hesitation replaced the order and shipped it next day to me. That is amazing customer service. I will be a customer from here on out because of that.

I've used other peptide companies and the customer service at this company is 5 star for sure. They sent me the wrong product and immediately they are sending me out two new bottles and told me to keep the other ones.I like how they include the water.And a syringe with it for mixing. At this point I will continue to use this company for my peptides

Received my package less than a week after ordering. Packaging is neat, beautiful, and reconstitution is seamless. Very high quality peptides with no cloudiness. I cannot get over how cute the packaging is. What a great company!! I have been looking for MONTHS to find a reputable company and stumbled across this one with not a whole lot of reviews but figured I would give it a shot. I am amazed with how perfectly seamless the process has been. All COAs are publicly available
