Frequently asked questions

Our rankings are based on a weighted scoring system: purity verification (40%), third-party COA transparency (20%), pricing (15%), shipping speed and reliability (15%), and customer reputation (10%). We review each vendor quarterly and update rankings accordingly.
A quality COA should include HPLC purity analysis (look for 98%+), mass spectrometry data confirming molecular identity, the name of the independent testing lab, batch/lot number, and date of analysis. Avoid vendors who only provide in-house testing.
Yes. All vendors on PeptideRanker sell peptides labeled for research use only. We verify that each vendor provides proper documentation, uses third-party testing, and has a consistent track record of quality and fulfillment.
Rankings are reviewed and updated monthly. We monitor vendor quality, pricing changes, new COA data, shipping reliability, and community feedback on an ongoing basis. Major changes trigger immediate updates.
