Scores you can check
Every vendor gets a Trust Score from 0 to 100 on the same five public criteria. Third-party lab certificates carry the most weight.
Read the scoring methodPrices an editor approves
A scraper flags price changes and an editor approves them. It cannot read every store, so check the vendor before you buy.
How prices are trackedPublished studies first
Compound profiles start from PubMed and ClinicalTrials.gov. If there is clinical data, we use it.
Editorial standardsHow the site earns money
Some vendors pay a commission when you buy through our links. No vendor can pay for a better score or a review.
Affiliate disclosureEverything listed here is for laboratory and research use only. Nothing on this site is medical advice.
