Every chart you need for copper peptide protocols organized in one comprehensive resource.

The tables below cover injectable protocols from 1mg to 3mg daily, topical applications from 0.5% to 4% concentration, and reconstitution calculations for both 50mg and 100mg vials.

Each section includes specific numbers for different goals, whether you are targeting skin rejuvenation, hair restoration, wound healing, or general anti-aging benefits. SeekPeptides created this as the definitive chart reference for GHK-CU protocols.

Master GHK-CU Dosage Chart by Goal

Different objectives require different approaches. The chart below provides complete dosage recommendations organized by your primary goal, including administration method, dose range, frequency, and expected cycle duration.

This master chart provides your starting point. The dosing calculations below will help you translate these ranges into specific injection volumes based on your vial size and reconstitution method. For detailed injection-specific protocols, the numbers above serve as your baseline reference.

Weight-Based GHK-CU Dosage Calculations

While most GHK-CU protocols use flat dosing rather than weight-based calculations, understanding how body weight affects dosing helps you fine-tune your approach.

Research in animal models shows activity at approximately 0.5mcg/kg, though human protocols typically use standardized doses in the 1-3mg range regardless of body weight.

Flat Dosing Reference Chart

The table below shows standard flat dose recommendations without weight adjustment, which represents how most practitioners approach GHK-CU.

Weight-Adjusted Calculation Chart

For those who prefer weight-based calculations, the following chart provides dosing ranges based on body weight using the common mcg/kg approach. These calculations use 15-30mcg/kg as the reference range.

Most practitioners find that flat dosing works perfectly well for GHK-CU. The weight-adjusted approach matters more for peptides with narrow therapeutic windows or those where body composition significantly affects distribution.

For GHK-CU, research shows effectiveness across a wide range, making precise weight calculations less critical than consistent administration.

50mg Vial Reconstitution Charts

Proper reconstitution determines your dosing accuracy.

The charts below show exactly how much bacteriostatic water to add and how many units to draw for your target dose from a 50mg vial.

Reconstitution Volume Options for 50mg Vial

50mg Vial Injection Volume Chart (2.5mL BAC Water)

Using 2.5mL of bacteriostatic water is the most common approach for 50mg vials. This creates a 20mg/mL concentration where 10 units equals 2mg. The chart below shows exact injection volumes for various doses.

Quick Reference Formula

For any reconstitution calculation, use this formula:

Units to draw = (Desired dose in mg / Total mg in vial) × Total units of BAC water added × 100

Example: For 2mg from a 50mg vial reconstituted with 2.5mL (250 units) BAC water:

(2mg / 50mg) × 250 units = 10 units

This formula works for any vial size and any reconstitution volume, making it essential for accurate peptide dosing.

100mg Vial Reconstitution Charts

Larger vials offer better value but require careful storage consideration since reconstituted peptides should be used within 30 days.

The charts below help you choose the right reconstitution volume for your protocol.

Reconstitution Volume Options for 100mg Vial

100mg Vial Injection Volume Chart (3.0mL BAC Water)

Adding 3.0mL to a 100mg vial creates a 33.3mg/mL concentration.

This is a practical choice that keeps injection volumes small while fitting within standard vial capacity.

Note that 100mg vials at daily 2mg dosing provide 50 days of product, which exceeds the 30-day reconstituted stability recommendation. Consider splitting the powder into two sterile vials before reconstitution if using lower doses, or choose 50mg vials for protocols requiring less than 2mg daily. SeekPeptides recommends matching vial size to your protocol duration for optimal potency.

Topical GHK-CU Concentration Guide

Topical copper peptide concentrations vary significantly based on application area and goal. The chart below provides complete guidance on selecting the right concentration for your needs.

Concentration by Application Area

Concentration Effectiveness Chart

Research supports specific concentration ranges for different skin benefits.

The following chart shows what you can expect at various concentrations based on available clinical evidence and user experiences documented across the peptide research community.

The 2-4% range represents the optimal balance between effectiveness and tolerability for most users. Higher concentrations may accelerate results but increase risk of temporary irritation. The general principle with copper peptides is that excessive application can break down tissue faster than regeneration occurs, so more is not always better.

Cycle Length Reference Charts

Cycling GHK-CU helps maintain receptor sensitivity and prevents potential copper accumulation.

The charts below provide cycle recommendations based on your goals and experience level.

Cycle Duration by Goal

Progressive Dosing Schedule

Many researchers prefer a titration approach that starts conservatively and increases over time. This chart shows a standard progressive protocol for a 12-week cycle.

This progressive approach helps identify your optimal dose while minimizing potential side effects. Some users find they respond well to lower doses and never need to reach the peak phase amounts. Others require the full 2mg daily for noticeable results. Starting low and titrating up remains the safest approach.

Administration Frequency Charts

How often you administer GHK-CU affects both results and practicality. The charts below compare different frequency protocols and their typical outcomes.

Injectable Frequency Comparison

Optimal Timing Chart

The timing of your GHK-CU administration can influence results, though the peptide is relatively flexible compared to growth hormone releasing peptides.

For most users, evening administration provides the best balance of effectiveness and convenience. The body does most tissue repair during sleep, making evening dosing physiologically advantageous. However, consistency matters more than timing. Pick a time that works for your schedule and stick with it.

Stacking Reference Charts

GHK-CU combines well with several other peptides for enhanced results.

The charts below show common stacking combinations and their synergistic benefits.

Popular GHK-CU Stack Combinations

The Glow Stack Protocol

One of the most popular combinations is the Glow Stack, which combines GHK-CU with TB-500 for comprehensive skin and tissue benefits.

When stacking multiple peptides, use the peptide stack calculator to manage total volumes and timing.

Most stacks can be administered in the same injection if using the same delivery method, though some practitioners prefer separating them by several hours.

What Not to Stack

While GHK-CU is generally safe to combine with most peptides, certain combinations require caution or are not recommended.

For guidance on combining copper peptides with retinoids, start with alternating days before progressing to same-day use. This approach from SeekPeptides protocols minimizes irritation while maximizing benefits.

Side Effects Monitoring Chart

GHK-CU has an excellent safety profile, but monitoring for potential effects helps optimize your protocol. The chart below lists what to watch for and when to adjust.

Common Side Effects Reference

When to Adjust Protocol

The vast majority of GHK-CU users experience no significant side effects. Studies note that copper peptides have "a long history of safe use in wound healing and skin care" and are active at very low concentrations. The lethal dose in humans would be approximately 21,000mg for a 70kg person, making the 1-3mg daily doses used in typical protocols extremely safe from a toxicity standpoint.

Frequently Asked Questions

What is the standard GHK-CU dose for beginners?

Beginners typically start with 0.5-1mg administered subcutaneously 3-5 times per week. This allows assessment of tolerance before increasing to standard therapeutic doses of 1-2mg daily.

How do I calculate units to draw from my syringe?

Use the formula: (Desired dose ÷ Total peptide in vial) × Total BAC water units × 100. For example, for 2mg from a 50mg vial with 2.5mL BAC water: (2÷50) × 250 = 10 units. The reconstitution calculator automates this calculation.

Can I use GHK-CU topically and by injection simultaneously?

Yes, many protocols combine both methods for comprehensive benefits. The injectable form provides systemic effects while topical application targets specific areas directly.

How long until I see results from GHK-CU?

Initial changes like improved skin hydration often appear within 2-4 weeks. More significant results for anti-aging typically require 8-12 weeks, while hair restoration often needs 16-24 weeks of consistent use.

What happens if I miss a dose?

Missing occasional doses does not significantly impact results. Simply continue with your next scheduled dose, do not double up. Consistency over weeks matters more than perfect daily adherence.

Is GHK-CU safe for long-term use?

Current evidence supports excellent safety for long-term use with appropriate cycling. The peptide occurs naturally in the body and has decades of research supporting its safety profile.

What concentration of topical GHK-CU should I use?
