Great products, not consumer friendly

The peptide quality is genuinely diagnostic-grade — I verified purity via our lab's HPLC and everything matched their COA. But their website is clearly designed for lab managers and institutional buyers, not individual researchers. Order took 10 days which is slow. If you have patience and need that level of documentation, fine. Otherwise look elsewhere.

Lab-grade quality, B2B oriented

Plexus is more of a lab supplier than a typical peptide shop. The documentation that comes with each order is extensive — way beyond what you get from most research peptide vendors. Ordered GLP-1 compounds for a university study. Quality was excellent but the ordering process is more suited for institutional buyers. If you need rigorous documentation for research purposes, this is a good source.
