PEPTIDE VENDORS 

We do not rate nor explicitly recommend vendors, although we are affiliated with some. Each researcher must conduct their due diligence to verify the vendor's Certificate of Analysis and guarantees. We have simply organized them in Green, Yellow, Orange and Red categories.

Green - Vendors in this category are ones that we have personally used in our research and that have a wide positive reputation in multiple peptide research communities. 

Yellow - Vendors in this category are ones that we don't have information on, haven't heard anything negative about them or haven't worked with them. We are affiliated with some of these vendors because we believe they are good and will try them in the future.

Orange - Vendors in this category raised some flags for us and we recommend extra caution until new information is available.

Red - Vendors in this category are ones which we would avoid due to lack of information on their website, negative reviews from the general community, and if we have had bad experiences with them. We always try to update our website and if they change the info provided on their sites we will adjust their status accordingly. It means be careful!
