HCG (5000 IU Vial): reconstitution reference for research laboratories. Includes the diluent volume and resulting concentration, syringe-unit conversion, vial and consumable planning, and storage guidance.
Quickstart
Reconstitute: Add 2.0 mL bacteriostatic water → 2,500 IU/mL concentration.
Typical dosing: 500 IU subcutaneous, 3× weekly (Mon/Wed/Fri) for testicular maintenance during TRT.
Easy measuring: At 2,500 IU/mL, 1 unit = 25 IU on a U‑100 insulin syringe.
Storage: Lyophilized: refrigerate at 2–8 °C (35.6–46.4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) for up to 60 days.
Notes
Practical considerations for safe and effective HCG administration. Sterile Technique: Use new sterile insulin syringes; wipe vial stopper with alcohol before each draw; never reuse needles [10]. Site Rotation: Rotate between abdomen (2+ inches from navel), outer thighs, and upper arms to prevent irritation and lipohypertrophy [10]. Injection Speed: Inject slowly; wait 5–10 seconds before withdrawing needle to ensure full dispersal. Monitoring: Consider periodic testosterone and estradiol testing; HCG can increase estradiol conversion in some individuals. Documentation: Track injection dates
