Standard reconstitution (10mg/ml) Most common protocol: 50mg GHK-Cu powder Add 5ml bacteriostatic water Creates 10mg/ml concentration Easy math for dosing How to calculate doses: 1mg dose = 0.1ml (10 units on insulin syringe) 2mg dose = 0.2ml (20 units) 3mg dose = 0.3ml (30 units) Total doses: 25 doses at 2mg each Why this concentration works: Simple calculations Easy to measure Standard for anti-aging protocols Fits insulin syringe well Alternative reconstitution (5mg/ml) More dilute option: 50mg GHK-Cu powder Add 10ml bacteriostatic water Creates 5mg/ml concentration Dose calculations: 1mg dose = 0.2ml (20 units) 2mg dose = 0.4ml (40 units) 3mg dose = 0.6ml (60 units) Total doses: 25 doses at 2mg each Why use 5mg/ml: Larger injection volume (some prefer) Easier to measure precisely Less concentrated (gentler on tissue) Good for beginners High concentration option (20mg/ml) Concentrated protocol: 50mg GHK-Cu powder Add 2.5ml bacteriostatic water Creates 20mg/ml concentration Dose calculations: 2mg dose = 0.1ml (10 units) 3mg dose = 0.15ml (15 units) 4mg dose = 0.2ml (20 units) When to use: Want smaller injection volume Using higher doses (3-5mg) Experienced users Prefer concentrated solutions Recommendation: Start with 10mg/ml (50mg + 5ml water) - simplest and most versatile
