BeaCapra GHK-Cu + AHK-Cu Blend — The Skin Stack
Frequently Bought Together
The Skin Stack: Combined Anti-Aging Copper Peptide Protocol
The BeaCapra Skin Stack combines two research-grade copper peptides—GHK-Cu and AHK-Cu—in a single 100mg lyophilized blend (50mg GHK-Cu + 50mg AHK-Cu). This dual copper peptide formulation enables researchers to investigate complementary dermal and follicular regeneration pathways in a single protocol. Each vial is verified at ≥99% purity by HPLC and mass spectrometry.
GHK-Cu and AHK-Cu share a copper-binding tripeptide structure but interact with distinct receptor populations and downstream signaling cascades. GHK-Cu research has focused on broad tissue remodeling, gene expression modulation, and antioxidant enzyme activation, while AHK-Cu studies have emphasized dermal papilla cell stimulation and extracellular matrix protein production.
The Skin Stack provides a streamlined approach for researchers investigating multi-pathway approaches to skin aging, wound repair, and hair follicle biology. The combined formulation eliminates the need for separate reconstitution and allows precise co-administration in research protocols.
Storage: Store lyophilized peptide at -20°C. Reconstitute with sterile water and store at 2-8°C. Use within 30 days. Protect from light and oxidation.

Research Benefits
- Synergistic Copper Peptide Activity: Combines two bioactive copper-binding tripeptides with complementary tissue remodeling mechanisms
- Enhanced Collagen Synthesis: Both peptides promote collagen I and III production through distinct signaling pathways, potentially offering amplified extracellular matrix remodeling
- Wound Healing Research: GHK-Cu's well-established wound healing properties enhanced by AHK-Cu's additional pro-collagen signaling
- Anti-Aging Skin Research: Investigated for combined effects on dermal thickness, elastin production, and glycosaminoglycan synthesis
- Gene Expression Modulation: GHK-Cu alone modulates over 4,000 genes; the combination may offer broader transcriptomic effects
Mechanism of Action
GHK-Cu (Glycyl-L-Histidyl-L-Lysine:Copper)
- Naturally occurring human plasma peptide that declines with age
- Binds copper(II) ions and delivers them to metalloenzymes essential for tissue repair (lysyl oxidase, SOD)
- Activates TGF-beta and VEGF signaling for tissue remodeling and angiogenesis
- Modulates 32% of the human genome according to Broad Institute genomic studies
AHK-Cu (Alanyl-L-Histidyl-L-Lysine:Copper)
- Synthetic copper peptide analog with enhanced collagen-stimulating properties
- Activates distinct SMAD signaling pathways for Type I collagen gene transcription
- Stronger procollagen I synthesis activity compared to GHK-Cu in comparative studies
- Complementary mechanism provides additive collagen production when combined
Research Protocol
For research purposes only. Not for human consumption.
- Typical Research Dose: 1-3 mg total copper peptide per administration
- Administration: Subcutaneous injection; topical application in dermatological research
- Research Cycle: 4-8 weeks in skin/wound healing studies
- Frequency: Once daily in most published protocols
Reconstitution
- Reconstitute with bacteriostatic water; solution will have characteristic blue-green copper hue
- Refrigerate at 2-8 °C; use within 30 days
Safety & Storage
- Lyophilized: Store at -20 °C long-term; 2-8 °C up to 6 months
- Reconstituted: 2-8 °C; use within 30 days
- Protect from light (copper complexes are photosensitive)
Research Considerations
- GHK-Cu has an extensive safety record in both research and cosmetic applications
- Monitor copper levels in long-term research protocols; excessive copper can be pro-oxidant
- Individuals with Wilson's disease or copper metabolism disorders should be excluded from research protocols
- For research use only
Frequently Asked Questions
-
Why combine GHK-Cu and AHK-Cu?
While both are copper-binding tripeptides, they activate different downstream signaling pathways for collagen synthesis. GHK-Cu has broader gene expression effects (4,000+ genes) while AHK-Cu shows stronger direct procollagen I stimulation, making the combination more comprehensive than either alone.
-
Why is the solution blue-green?
The blue-green color is characteristic of copper(II) peptide complexes and indicates proper copper binding. This is normal and expected.
-
Can this be used topically?
Published research includes both injectable and topical applications. Copper peptides are well-established in dermatological research for topical use, though subcutaneous administration provides systemic distribution.
-
What purity is this product?
≥99% purity for both peptides, verified by HPLC and mass spectrometry. COA available.
