Injectable GHK-Cu is typically dosed at 200 to 500 mcg per day subcutaneously, while BPC-157 is dosed at 250 to 500 mcg per day, with both peptides used alongside topical GHK-Cu applied once or twice daily. Dosing varies by treatment phase, specific skin concern, and whether you are using injectable, topical, or combined administration routes.

GHK-Cu Dosage: Injectable

Subcutaneous Injection

• Starting dose: 200 mcg per injection
• Standard therapeutic dose: 200-500 mcg per injection
• High dose: 500-1000 mcg per injection (used in some aggressive skin repair protocols)

Frequency by Phase

• Intensive phase (weeks 1-4): Once daily
• Optimization phase (weeks 5-8): 3-5 times per week
• Maintenance phase (ongoing): 2-3 times per week

Injection Site Selection

For general skin rejuvenation, inject subcutaneously in the abdomen. For localized concerns (facial aging, specific scars), some practitioners inject near the target area. GHK-Cu has systemic effects, so abdominal injection benefits skin throughout the body.

GHK-Cu Dosage: Topical

Serum or Cream Application

• Concentration: 0.01% to 1% GHK-Cu in serum or cream form
• Application: Apply a thin layer to clean, dry skin
• Frequency: Once or twice daily (AM and/or PM)
• Target areas: Face, neck, decolletage, hands, or any area of concern

Topical GHK-Cu does not require cycling and can be used continuously as part of a daily skincare routine.

Post-Microneedling Application

When used immediately after microneedling, GHK-Cu serum penetrates deeper through the micro-channels. Apply liberally to the treated area immediately post-procedure and continue twice-daily application during the healing period. Some practitioners use GHK-Cu as the "glide serum" during the microneedling procedure itself.

BPC-157 Dosage for Skin Applications

Subcutaneous Injection

• Standard dose: 250-500 mcg per injection
• Frequency (intensive): Once or twice daily
• Frequency (maintenance): Once daily or 3-5 times per week

Injection Placement for Skin Goals

• General skin rejuvenation: Abdomen (systemic distribution)
• Specific scar treatment: Near the scar site
• Wound healing: Near the wound perimeter (not into the wound)
• Post-surgical skin repair: Near the incision site

BPC-157's effects are strongest locally, so injection near the target area is preferred for localized concerns. For whole-body skin improvement, abdominal injection is practical and effective. BPC-157 injection placement

Reconstitution and Volume Calculations

GHK-Cu

GHK-Cu typically comes in 5 mg or 10 mg vials. For a 5 mg vial reconstituted with 2 mL of bacteriostatic water:

• Concentration = 2.5 mg/mL (2500 mcg/mL)
• 200 mcg = 0.08 mL (8 units on an insulin syringe)
• 300 mcg = 0.12 mL (12 units)
• 500 mcg = 0.2 mL (20 units)
• One 5 mg vial provides 25 doses at 200 mcg or 10 doses at 500 mcg

BPC-157

BPC-157 commonly comes in 5 mg vials. Reconstituted with 2 mL of bacteriostatic water:

• Concentration = 2.5 mg/mL (2500 mcg/mL)
• 250 mcg = 0.1 mL (10 units)
• 500 mcg = 0.2 mL (20 units)
• One 5 mg vial provides 20 doses at 250 mcg or 10 doses at 500 mcg

Storage

• Store reconstituted vials in the refrigerator (36-46 degrees F / 2-8 degrees C)
• Do not freeze reconstituted peptides
• Use reconstituted peptides within 3-4 weeks
• Unreconstituted powder can be stored at room temperature short-term or frozen for long-term storage
• Topical GHK-Cu products: follow manufacturer storage instructions (usually room temperature, away from direct sunlight)

Dose Adjustment Guidelines

When to Consider a Higher Dose

• Minimal visible improvement after 4-6 weeks at standard doses
• Severe skin damage, deep scarring, or significant photoaging
• Larger body size (over 200 lbs)
• Good tolerance with no side effects at current dose

When to Consider a Lower Dose

• Any skin irritation or sensitivity (uncommon but possible)
• Smaller body size (under 130 lbs)
• During maintenance phase when goals are being met
• Budget constraints requiring longer treatment duration at lower cost

Cost at Different Dose Levels

• Standard intensive: $150-300/month
• Aggressive scar/wound protocol: $250-400/month

Frequently Asked Questions

What is the minimum effective dose of GHK-Cu for skin benefits?

For injectable GHK-Cu, 200 mcg per injection administered 2-3 times per week is generally considered the minimum effective dose for visible skin benefits. Topically, concentrations as low as 0.01% have shown measurable effects on collagen production in studies, though higher concentrations (up to 1%) may produce faster results.

Should I use higher doses for deeper wrinkles?

Deeper wrinkles may benefit from higher GHK-Cu doses (400-500 mcg) and longer treatment duration rather than just standard doses. However, consistency and duration of use typically matter more than dose intensity. A standard dose used consistently over 3-6 months often outperforms a high dose used inconsistently.

Can I use topical GHK-Cu alone without injections?

Yes. Topical GHK-Cu alone provides meaningful skin benefits and is the most accessible form of copper peptide therapy. It is effective for surface-level improvements in skin texture, firmness, and tone. Adding injectable GHK-Cu and BPC-157 provides deeper, systemic support that amplifies topical results. topical peptide skincare

How do I calculate my dose from a reconstituted vial?

Divide the total peptide amount by the volume of water used to reconstitute. For example: 5 mg peptide in 2 mL water = 2.5 mg/mL = 2500 mcg/mL. For a 250 mcg dose, draw 0.1 mL (10 units on a standard 100-unit insulin syringe). For a 500 mcg dose, draw 0.2 mL (20 units). peptide dosing calculator
