GHK-Cu dosage chart for a 100 mg vial, including 3 mL reconstitution, U-100 syringe calculations, research protocol tables, supplies, and citations.
GHK-Cu Dosage Chart
This GHK-Cu dosage chart explains a 100 mg vial prepared to a final volume of 3.0 mL for a concentration of 33.33 mg/mL. The GHK-Cu dosage protocol examples below cover 1.0 mg, 1.5 mg, and 2.0 mg amounts, with matching U-100 syringe units, reconstitution steps, supplies, and research context.
Reconstitute: Prepare the 100 mg vial to a final volume of 3.0 mL for a concentration of 33.33 mg/mL.
Research protocol range: The tables below cover 1.0 mg, 1.5 mg, and 2.0 mg using the standard and alternative research-use schedules.
Easy measuring: At 33.33 mg/mL, 1 U-100 unit = 0.01 mL = approximately 333.3 mcg.
Quick conversions: 1.0 mg = 3 units, 1.5 mg = 4.5 units, and 2.0 mg = 6 units.
GHK-Cu, or glycyl-L-histidyl-L-lysine copper complex, is a naturally occurring copper peptide studied for collagen-related pathways, tissue remodeling, antioxidant defense, and skin repair[7][8]. This educational GHK-Cu dosage protocol presents the same research-use schedule for the 100 mg vial, with calculations adjusted for its concentration.
Research context: For evidence on mechanisms, human and preclinical research, limitations, and safety, read GHK-Cu Peptide: Benefits, Uses, Side Effects, Dosage, and Research.
Dosing & Reconstitution Guide
Educational guide for reconstitution and common dosing patterns
Standard / Conservative Approach (3 mL = 33.33 mg/mL; 5 days/week)
{"order":19,"rows":[["Week/Phase","Dose per Injection","Units (per injection) (mL)"],["Weeks 1-4","1.0 mg (1000 mcg)","3 units (0.03 mL)"],["Weeks 5-8","1.5 mg (1500 mcg)","4.5 units (0.045 mL)"],["Weeks 9-12+","2.0 mg (2000 mcg)","6 units (0.06 mL)"]],"skip_markdown":false,"type":"table"}
Frequency: Once daily, 5 days per week, progressing from 1.0 mg to 1.5 mg and then 2.0 mg as shown above. At 33.33 mg/mL, those doses equal 3, 4.5, and 6 U-100 units[18]. Use a U-100 syringe with markings that clearly display every value in the table.
Reconstitution Steps
Draw 3.0 mL of the protocol-specified sterile diluent with a sterile syringe.
Add it slowly down the vial wall to reduce foaming.
Gently swirl or roll until dissolved. Do not shake.
Label the vial with the 33.33 mg/mL concentration, preparation date, and storage instructions.
Alternative Protocol (3 mL = 33.33 mg/mL; 3 times weekly)
{"order":27,"rows":[["Week/Phase","Dose per Injection","Units (per injection) (mL)"],["Weeks 1-12+","2.0 mg (2000 mcg)","6 units (0.06 mL)"]],"skip_markdown":false,"type":"table"}
Frequency: 2.0 mg three times per week, such as Monday, Wednesday, and Friday. At 33.33 mg/mL, each injection equals 6 U-100 units (0.06 mL), for approximately 6 mg per week[18].

Protocol Overview
Concise summary of the GHK-Cu dosage protocol and 100 mg vial calculations.
Goal: Present GHK-Cu research dosage, reconstitution, supplies, and measurement context in one consistent protocol.
Schedule: The standard table uses 5 days per week; the alternative table uses 3 times per week.
Amount Range: 1.0 to 2.0 mg per administration within the research protocol examples.
Reconstitution: A final volume of 3.0 mL produces 33.33 mg/mL.
Measurement: 1.0 mg equals 3 units, 1.5 mg equals 4.5 units, and 2.0 mg equals 6 units.
Dosing Protocol
Research-use protocol examples with verified 100 mg vial conversions.
Standard model: Weeks 1 to 4 use 1.0 mg or 3 units; weeks 5 to 8 use 1.5 mg or 4.5 units; weeks 9 to 12+ use 2.0 mg or 6 units.
Alternative model: 2.0 mg or 6 units, three times per week.
Route context: The tables present subcutaneous research-use calculations.
Cycle context: The main table covers 8 to 12+ weeks, while the Supplies Needed section also provides totals through 16 weeks.
Protocol source: These schedules reflect practice conventions summarized by a compounding source[18]. Published evidence is summarized lower on the page.
Storage Instructions
Storage requirements should match the exact GHK-Cu preparation.
Dry material: Follow the vial and batch documentation for temperature, moisture, and light protection[13].
Prepared solution: Stability depends on concentration, pH, diluent, sterility, container, preservatives, and temperature.
Handling: Minimize unnecessary light, moisture exposure, and repeated freeze-thaw cycles[13][14].
Recordkeeping: Record the preparation date, concentration, storage temperature, and applicable disposal date.
Important Notes
Practical considerations for consistent research preparation and recordkeeping.
Use new sterile equipment for each preparation or administration and use a suitable sharps container[17].
Follow the written protocol for site selection and rotation[15].
Use aseptic technique and allow skin antiseptic to dry before administration[16].
Document the amount, date, preparation identifier, and site used.
Research Evidence Context
Published human GHK-Cu research has primarily evaluated topical and wound-care formulations[1][2][3][4][5], while local administration in an animal wound model provides additional preclinical context[6]. The subcutaneous schedules above are research-use practice conventions[18], so findings should be interpreted according to route and formulation. Current clinical-trial and FDA materials provide additional topical, compounding, and regulatory context[9][10][11][12].
How This Works
GHK-Cu is a naturally occurring copper-binding tripeptide studied in extracellular-matrix signaling, collagen-related pathways, antioxidant defense, and tissue remodeling[7][8]. Human studies provide topical and wound-care context[1][2][3][4][5], while an animal wound model provides local-administration context[6].
Potential Benefits & Observed Effects
Findings reported in the GHK-Cu research literature.
Supports research into collagen-related signaling, extracellular-matrix remodeling, and tissue repair[6][7][8].
Human topical and wound-care studies have examined skin and tissue outcomes in formulation-specific settings[1][2][3][4].
Human-skin penetration research provides additional topical-delivery context[5].
Observed findings depend on route, formulation, concentration, and study design; the supporting context is summarized in Important Notes above.
Lifestyle Factors
Complementary approaches to support tissue health and regeneration.
Maintain adequate protein intake to support collagen synthesis and tissue repair processes.
Ensure sufficient hydration and micronutrient status (particularly copper, zinc, vitamin C) for optimal connective tissue metabolism.
Prioritize sleep quality and stress management to support regenerative biological processes.
Consider combining with appropriate skincare or wound-care protocols as relevant to individual goals.
Injection Technique
General subcutaneous technique references are included for preparation and measurement context[15][16][17].
Follow aseptic technique and use new sterile equipment for each administration.
Use the protocol-specified site, angle, and device; the CDC job aid illustrates general subcutaneous technique[16].
Rotate sites systematically and document each administration[15].
Dispose of used sharps immediately in an appropriate container[17].
