Fertility Preservation / TRT Adjunct Weekly Protocol Guide

HCG 5000IU Protocol Guide

✓ Verified dosing (fact-checked against FDA labels / published trials): Route: the FDA label specifies intramuscular, but subcutaneous is widely used and accepted in fertility/TRT research practice (off-label, effective). Male hypogonadotropic hypogonadism: 500-1,000 USP Units IM 3x/week x3 wks, then 2x/week x3 wks; OR 4,000 USP Units IM 3x/week x6-9 mo, then 2,000 USP Units 3x/week x3 mo. Doses are in USP Units, reconstituted from 5,000 or 10,000-unit vials. The "2-3x per week" frequency is consistent with the male regimen, and the route is flexible — IM per label, or SubQ in common practice. This supersedes any conflicting figures shown elsewhere on this page; confirm with a licensed provider.

HCG is a naturally occurring hormone used in research for fertility preservation and as a TRT adjunct. It mimics luteinizing hormone (LH) to stimulate testicular function, supporting endogenous testosterone production and spermatogenesis during exogenous hormone protocols.

Protocol Overview

Compound
HCG 5000IU (Human Chorionic Gonadotropin)
Category
Fertility Preservation / TRT Adjunct
Vial Size
5000IU (5,000 IU)
Reconstitution
2mL bacteriostatic water (2,500 IU/mL)
Route
Subcutaneous injection
Frequency
3 days/week

Reconstitution Instructions

Using 2mL of bacteriostatic water results in a concentration of 2,500 IU/mL. Always use sterile techniques.

Materials Needed

  • 5000IU HCG 5000IU vial (lyophilized powder)
  • 2mL bacteriostatic water (sterile, preserved with 0.9% benzyl alcohol)
  • Sterile syringe and needle (18-22 gauge for drawing)
  • Alcohol swabs
  • Clean workspace

Step-by-Step Process

  1. Preparation: Allow the HCG 5000IU vial and bacteriostatic water to reach room temperature. Wipe the rubber stoppers of both vials with an alcohol swab.
  2. Draw the Water: Using a sterile syringe, draw up exactly 2mL of bacteriostatic water. Expel any air bubbles.
  3. Inject into Vial: Insert the needle through the rubber stopper at a slight angle, aiming toward the glass wall. Slowly inject the water down the side of the vial to avoid foaming.
  4. Mix Gently: Remove the needle. Gently swirl or roll the vial between your hands. Do not shake vigorously.
  5. Check for Clarity: The solution should be clear once fully reconstituted. Do not use if cloudy.

Administration Guidelines

  • Administer subcutaneously or intramuscularly as directed
  • Rotate injection sites between abdomen, thigh, and upper arm
  • Common protocol is 250-500IU 2-3x per week alongside TRT
  • Store reconstituted peptide refrigerated at 36-46F (2-8C)
  • Use reconstituted solution within 30 days
  • Never freeze reconstituted peptides
  • Document administration times and observations
