Frequently Asked Questions
Everything researchers ask about purity, COAs, shipping, and research-use policies.
What purity level are your peptides and how is it verified?
MGR Peptides compounds are supplied as research-grade materials with third-party identity and purity testing. Certificates of Analysis document batch-level results. Review COAs on the COAs page and on individual product pages as they are uploaded.
What is a Certificate of Analysis (COA)?
A COA is a laboratory document verifying the batch’s identity and purity (commonly via HPLC / mass spectrometry). Each COA is batch-specific. If a product page does not yet list a COA PDF, contact us with the product and batch number.
How do I choose MG size?
Each compound is sold as a variable product. On the product page, select Size (mg)—for example 5mg, 10mg, 15mg, and higher. Price updates for the selected size before you add to cart.
How fast do you ship?
