SP Biolabs GHK-Cu Peptide Renewal Serum (7%)

Cold. Clean. Clinical.
The SP Biolabs GHK-Cu Serum is a laboratory-grade peptide formulation designed to restore, repair, and rejuvenate the skin. Developed through our in-house peptide research program, it delivers a high-potency 7% GHK-Cu concentration, stabilized via cold manufacturing and small-batch precision blending.

Why We Created It

Most copper peptide serums contain less than 1% active GHK-Cu — too diluted for a measurable response. After extensive formulation testing, we found that 7% GHK-Cu offers an optimal balance of stability, absorption, and collagen stimulation — without irritation. We built this serum for athletes, clinicians, and researchers who expect results, not marketing claims.

Clinical-Grade Formula

Ingredient	Function
GHK-Cu (Copper Tripeptide-1) 7%	Stimulates collagen synthesis; accelerates visible skin repair
Hyaluronic Acid 2%	Deep hydration; improves elasticity and plumpness
D-Panthenol 1%	Strengthens skin barrier; calms irritation
Vegetable Glycerin 0.5%	Locks in lasting moisture
Phenoxyethanol 0.5%	Gentle preservative; stability support

pH: 5.8–6.2 | Fragrance-Free | Color: Natural Sky Blue

Why Cold Storage Matters

True GHK-Cu peptides are temperature-sensitive. Heat and oxygen gradually oxidize the copper complex, reducing potency and shifting color. SP Biolabs uses Cold Manufacturing Technology and recommends refrigerated storage at 35–40 °F (1–4 °C) to preserve maximum activity. When kept cold, the serum maintains full efficacy for up to 90 days.

Cold Stored = Full Potency

Cold Packaging Included

Every SP Biolabs face serum ships with temperature-controlled cold packaging — free of charge. Your bottle arrives chilled, fresh, and bioactive, exactly as formulated in our lab.

FAQ

Is the 7% GHK-Cu concentration suitable for daily use?

Yes. Our pH-optimized base and small-batch cold manufacturing keep the formula potent yet gentle for daily use on most skin types. Patch test if you have very sensitive skin.

Why does the serum have a light blue color?

The natural sky-blue hue comes from the copper complex of GHK-Cu. We do not add dyes.

Do I need to keep it in the refrigerator?

Refrigeration at 35–40 °F (1–4 °C) maximizes stability and preserves full peptide activity for up to 90 days. We also ship every face serum with free cold packaging.

Why SP Biolabs GHK-Cu Serum Outperforms Other Brands

Most so-called “peptide serums” on the market contain less than 1% of actual GHK-Cu — just enough to list it on the label, but not enough to make a biological difference.
Our formula was engineered from clinical peptide data to deliver 7× more active GHK-Cu than conventional products, while keeping the serum stable and non-irritating.

Feature	Typical Brands	SP Biolabs
GHK-Cu concentration	0.3 – 1%	7%
