How do I verify the quality of Semaglutide from a vendor?

To verify Semaglutide quality, look for an independent certificate of analysis (COA) from a third-party lab — not a lab the vendor owns or pays directly. The COA should state the tested compound, lot number, purity percentage (identity and concentration), and the lab's name. Cross-reference the lot number against the vendor's current stock. Merit Verified indexes COAs for Semaglutide at https://meritverified.org/peptides/semaglutide so you can compare evidence across vendors before buying.

What is the regulatory status of Semaglutide?

Semaglutide is tracked in the Merit Verified registry. Regulatory status for research peptides in the US has been evolving — the FDA has reclassified a number of peptides out of the 503A compounding ingredient list since 2025. Merit Verified does not provide legal or regulatory advice; check official FDA sources or consult a licensed professional for the current status of Semaglutide in your jurisdiction.
