Skin & peptides.
Read the form first.

A skincare ingredient and an injectable medicine can share a name. This guide helps keep their evidence and rules apart, before an appealing word does too much work.

Explore Promise Peptides for skin and longevity care

Promise Peptides prescribes now through licensed U.S. providers. A provider reviews each request and decides; not everyone qualifies. U.S. patients only. Availability varies by state and treatment. Compounded medicines are not FDA-approved.

Texture and shade, without a treatment claim.

A shared ingredient name does not connect the evidence for a cream and an injection.

A little less pressure around skin.

You do not have to treat your skin as a problem to be curious about these ingredients and the evidence.

The same care applies to words. “Glow” and “anti-aging” can carry large expectations. A treatment group’s name does not establish that a product changes skin or slows aging. The evidence needs to answer a more specific question.

Follow the form, not just the name.

GHK-Cu is a small peptide bound to copper. A peptide is a chain of amino acids, the building blocks of proteins. In skincare, GHK-Cu is often called Copper Tripeptide-1.

A topical product is placed on the skin. An injectable preparation is a different form with different safety questions. Small studies of creams cannot show what happens after an injection. Laboratory work on skin cells is a different setting again.

Approval stays specific.

No medicine containing GHK-Cu has FDA approval. Cosmetics and medicines follow different rules; seeing an ingredient in a serum does not establish approval of an injection. Compounded GHK-Cu is not FDA-approved.

The FDA’s page current as of April 22, 2026, lists injectable GHK-Cu as “nominated but withdrawn.” The withdrawn nomination is not FDA clearance or approval. Non-injected forms have a separate compounding-list history. It matters which form a sentence is about.

Let the conversation be personal.

Promise groups these consultations under anti-aging and longevity. That name does not establish what a treatment will do. A licensed U.S. provider reviews every request and decides whether a prescription is appropriate. Not everyone qualifies.

  • Is this a cosmetic question or a prescription question?
  • Does the human research test this exact form?
  • What is known about safety, and what is not?
  • What other options fit the concern I am describing?

A pharmacy separately decides whether it can lawfully prepare a compounded prescription. Compounded medicines are not FDA-approved. A welcoming page and a licensed review have different jobs.

When a question needs a provider.

A consultation is a place for a licensed review of your health. It can end without a prescription. There is room for that answer too.
