Not approved; research use only
Sold as 'research use only'. Clinics linked to mixing pharmacies sell it, as well as research chemical sellers. That does not change its approval status.

A "research use only" label on a vial does not make it legal to use on people.

What this means
- 01
No product containing Quad healing blend is approved by FDA for any use in the United States. So nothing on sale is allowed for use in people.
- 02
"Research use only" is a label sellers put on. It is not a legal category that allows use in people, and it does not get a product out of medicines law.
- 03
Importing it, supplying it or promoting it for use in people can fall under medicines law in the United States. This page is general information, not legal advice.
What Quad healing blend is
The same four peptides as KLOW, mixed in very different amounts. It is usually 5 mg TB-500, 5 mg BPC-157, 10 mg KPV and 5 mg GHK-Cu in a 25 mg vial. Copper peptide is 20% of the powder here, against 62.5% in KLOW. That is roughly 0.8 mg of copper per vial instead of 7.9 mg. No study has tested any mix of these four, in people or animals.
This vial matters because of what it shows about blends in general. KLOW and this product have the same four ingredients.
How it works: Four effects, all assumed to add up, in one vial. GHK-Cu carries copper into tissue.
Approval history: Not approved. No regulator has reviewed any four-peptide blend like this.
How FDA treats this kind of product
Approves prescription drugs, each for a named use. It also acts against unapproved products, including peptides sold online. Compounding pharmacies, which mix drugs to order, may make some compounds with a prescription. That only applies when the FDA puts the compound in a category of bulk ingredients it allows.
The legal category above is how The Longevity Archive reads U.S. Food and Drug Administration listings for Quad healing blend on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.
Quad healing blend in sport and the military
Whether Quad healing blend is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in the United States. Before you compete or get tested, look up Quad healing blend by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
