- GHK-Cu
- 18–24 months
- 90–120 days
- <72 hours before 20% loss
- Copper dissociation + oxidation
- More temperature-sensitive than most growth factors due to metal chelation. Requires strict cold chain
- BPC-157
- 24–36 months
- 60–90 days
- 5–7 days before 20% loss
- Peptide bond hydrolysis
- More forgiving than GHK-Cu. Tolerates brief ambient exposure during handling
- Thymosin Beta-4
- 24 months
- 90 days
- 3–5 days before 20% loss
- Oxidative degradation of cysteine residues
- Similar stability profile to GHK-Cu. Both require refrigeration post-reconstitution
- Melanotan II
- 30–60 days
- 2–3 days before 20% loss
- Photodegradation + oxidation
- Less stable than GHK-Cu in solution. Must be protected from light as well as heat
