GHK-Cu IU Per Tick Insulin Syringe: Comparison of Concentrations

This source-based comparison does not add ratings or recommend a winner.

Before selecting a reconstitution volume, understand how concentration affects dosing precision and injection volume.
| Vial Size | Bacteriostatic Water Added | Final Concentration | Peptide Per Tick (0.01 mL) | 200 mcg Dose Volume | 500 mcg Dose Volume | Professional Assessment ||—|—|—|—|—|—|| 5 mg | 5 mL | 1 mg/mL | 10 mcg | 0.2 mL (20 ticks) | 0.5 mL (50 ticks) | Best for beginners. Larger volumes reduce measurement error and allow visual confirmation of dose accuracy || 10 mg | 2 mL | 5 mg/mL | 50 mcg | 0.04 mL (4 ticks) | 0.1 mL (10 ticks) | Requires precision. One-tick error equals 50 mcg variance; use only with calibrated 0.3 mL or 0.5 mL syringes || 10 mg | 5 mL | 2 mg/mL | 20 mcg | 0.1 mL (10 ticks) | 0.25 mL (25 ticks) | Middle-ground concentration balancing injection volume and dosing precision for multi-dose vials || 50 mg | 10 mL | 5 mg/mL | 50 mcg | 0.04 mL (4 ticks) | 0.1 mL (10 ticks) | High-throughput labs running 20+ injections per week. Minimises vial count but demands measurement discipline |
Concentrations above 5 mg/mL risk incomplete dissolution and peptide aggregation. GHK-Cu's copper chelation makes it more prone to precipitation at high concentrations than uncharged peptides like BPC-157. Concentrations below 1 mg/mL waste bacteriostatic water and require larger injection volumes that increase subcutaneous bolus size, which can affect local bioavailability in tissue repair models.
