Your protocol

How ETERNAL Blend is prescribed.

Who it's for
  • Adults who want better skin, faster recovery and healthy aging from one vial
  • People in their 40s and up noticing thinner skin and nagging aches that linger
  • Patients who like the KLOW-style repair peptides and want a longevity peptide added
  • Anyone replacing several single vials with one daily injection

Your physician decides whether ETERNAL Blend is appropriate for you after reviewing your intake and labs.

Directions & duration

Inject 0.25 mL (25 units) subcutaneously once daily Monday through Friday.

The science

How ETERNAL Blend works, and what the research shows.

How it works

GHK-Cu, the copper peptide, drives collagen and skin remodeling.

BPC-157 and TB-500 are studied for repairing tendons, ligaments and the gut lining.

Epithalon is studied for protecting the ends of chromosomes and for restoring the body's natural melatonin rhythm.

Clinical evidence
  • No clinical trial has studied this exact combination.

  • The evidence is for each peptide on its own, and your physician weighs that when deciding whether the blend fits you.
