GHK-Cu (50mg Vial) Research Protocol & Reconstitution Guide
Navigation Menu
Quickstart Protocol Highlights
GHK-Cu (Glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper complex that serves as a powerful gene-modulating regulator. Unlike standard repair peptides, GHK-Cu is researched for its ability to reset human gene expression to a more youthful state, primarily through the upregulation of DNA repair genes and the stimulation of the extracellular matrix.
Standard Dosing & Titration Schedule
In preclinical models, a structured titration approach is critical for GHK-Cu. The primary challenge in GHK-Cu research is not systemic toxicity, but localized "sting" or injection site reactions (ISR). By gradually increasing the milligram delivery, researchers can identify the subject's localized tolerance threshold while ensuring maximum systemic absorption.
| Research Duration | Daily Research Dose | Draw Volume (at 10mg/mL) |
|---|---|---|
| Weeks 1 – 2 (Introductory) | 1,000 mcg (1 mg) | 10 Units (0.10 mL) |
| Weeks 3 – 8 (Standard Protocol) | 2,000 mcg (2 mg) | 20 Units (0.20 mL) |
| Weeks 9 – 12 (Advanced Study) | 3,000 mcg (3 mg) | 30 Units (0.30 mL) |
Note: For research protocols exceeding 2,000 mcg daily, it is standard practice to split the dose into a morning and evening administration to further minimize localized tissue irritation.
Required Laboratory Supplies
GHK-Cu research requires a significantly higher volume of diluent than BPC-157 due to the larger mass of the peptide puck (50mg–100mg). Maintaining a sterile "cold chain" and environment is vital for maintaining the integrity of the copper complex.
Peptide Inventory
- GHK-Cu Vials: 6 x 50mg Vials (Total 300mg).
- Based on a 12-week, 2.5mg/day average protocol.
Diluents & Syringes
- Bacteriostatic Water: 5 x 10mL bottles (BWFI).
- Insulin Syringes: 100 x U-100 (0.5ml or 1.0ml).
Sanitization & Disposal
- Prep Pads: 200 x 70% Isopropyl Alcohol swabs.
- Sharps Container: 1 x Biohazard disposal unit.
Step-by-Step Reconstitution Guide
GHK-Cu is easily identified by its vibrant royal blue color, a result of the copper-binding tripeptide. Because of its density, a "High-Dilution" protocol is required. Using 5mL of water for a 50mg vial is the baseline for ensuring research data is not skewed by localized inflammation.
- Sterilization: Clean the rubber stoppers of both the GHK-Cu and the Bacteriostatic Water vials with fresh alcohol swabs.
- Pressure Management: Draw 5.0 mL of air into your syringe and inject it into the Bac Water vial to make drawing the larger volume easier.
- The 5mL Rule: Slowly draw 5.0 mL of Bacteriostatic Water. Diluting 50mg into 5mL creates a manageable 10mg/mL concentration.
- Low-Impact Drip: Insert the needle into the GHK-Cu vial at a 45-degree angle. Drip the water slowly down the side of the glass. Direct spraying can cause foaming and denaturation.
- Dissolution: Gently swirl the vial. GHK-Cu is highly soluble and will quickly turn the solution a clear, deep blue. Never shake the vial.
- Thermal Stabilization: Allow the solution to stabilize in the refrigerator (2–8°C) for 15 minutes before use.
Administration Technique & Site Rotation
GHK-Cu is administered via subcutaneous (SubQ) injection. Due to the high bioactivity of the copper complex, site rotation is mandatory to prevent localized fat irritation or temporary soreness.
- Selection: Choose areas with high adipose tissue (Abdomen, Outer Thighs).
- Speed of Delivery: Inject very slowly. A rapid "shot" of GHK-Cu is significantly more likely to cause a stinging sensation.
- The "Wipe" Technique: After removing the needle, do not rub the site. Apply light pressure with a clean alcohol swab if needed.
- Frequency: Rotate injection sites in a 2-inch radius daily to ensure localized tissue recovery.
Technical Appendix: Molecular Mechanics & Gene Modulation
This section details the advanced biological pathways activated by GHK-Cu, serving as a reference for institutional research models.
I. Gene Modulation: Resetting the Cellular Blueprint
The most profound aspect of GHK-Cu is its ability to modulate the expression of over 3,000 human genes. Research suggests it can reset genes associated with DNA repair to a more youthful state. This include the activation of the **Antioxidant Response Element (ARE)** and the downregulation of pro-inflammatory cytokines such as **IL-6 and TNF-alpha**.
II. Extracellular Matrix (ECM) Remodeling
GHK-Cu is a primary regulator of collagen synthesis. It stimulates the production of **Type I and Type III Collagen**, elastin, and glycosaminoglycans. By modulating the activity of metalloproteinases (MMPs) and their inhibitors (TIMPs), GHK-Cu facilitates a state of "ordered repair" rather than the disorganized scar tissue formation typical in natural healing.
III. Angiogenesis and Nerve Growth
GHK-Cu promotes the formation of new capillary networks, ensuring that oxygen and nutrients reach the dermis and underlying tissues. Furthermore, studies have shown it to be neuroprotective, stimulating nerve outgrowth and increasing the expression of **Nerve Growth Factor (NGF)**, which is critical for restoring sensation and function to damaged tissue.
IV. Stability, Storage, and lifecycle
GHK-Cu is more stable than BPC-157, but it is highly susceptible to copper-dissociation if exposed to improper environments.
- Lyophilized: Stable at room temperature for up to 90 days; -20°C for long-term (2+ years).
- Reconstituted: Must be refrigerated at 2–8°C. Potency remains high for 28–30 days. If the deep blue solution turns greenish or clear, the copper has dissociated and the peptide is compromised.
- Photosensitivity: UV light is a catalyst for peptide bond cleavage. Always store vials in the dark.
V. Advanced Troubleshooting & Research FAQ
Q: Why does GHK-Cu sting?
A: The copper ion in the complex is highly reactive. If the concentration is too dense (e.g., 50mg in only 2mL), it can irritate the subcutaneous layer. Always aim for a dilution of at least 10mg/mL (5mL of water per 50mg vial).
Q: Can I stack GHK-Cu with BPC-157?
A: Yes. In research models, GHK-Cu provides the collagen blueprint while BPC-157 provides the vascular "highway" to deliver repair materials. They are highly synergistic for deep tissue and musculoskeletal research.
Q: My solution has blue flakes at the bottom. What do I do?
A: This is incomplete dissolution. Do not shake. Place the vial in a warm (not hot) area for 5 minutes and gently swirl. If the flakes persist, the vacuum seal may have been compromised.
