Question 1

What is TB-500 + GHK-Cu?

Accepted Answer

Grey-market vendor blend combining TB-500 (a synthetic heptapeptide fragment of Thymosin Beta-4, not full-length Tβ4) and GHK-Cu (a copper tripeptide). This blend is not clinically validated; evidence is extrapolated from individual-component research, and no human trials of the combination exist. Merit Verified tracks independent COA test results for TB-500 + GHK-Cu from multiple vendors.

Question 2

Which vendors sell TB-500 + GHK-Cu with independent COA testing?

Accepted Answer

No independent COA is currently on file for TB-500 + GHK-Cu in the Merit Verified directory. Absence of a COA does not mean no vendors sell it — it means no third-party test result has been located or submitted yet.

Question 3

How do I verify the quality of TB-500 + GHK-Cu from a vendor?

Accepted Answer

To verify TB-500 + GHK-Cu 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 TB-500 + GHK-Cu at https://meritverified.org/peptides/tb-500-ghk-cu so you can compare evidence across vendors before buying.

Question 4

What is the regulatory status of TB-500 + GHK-Cu?

Accepted Answer

TB-500 + GHK-Cu 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 TB-500 + GHK-Cu in your jurisdiction.
