HCG (Human Chorionic Gonadotropin) 5000IU

When it comes to Testosterone Replacement Therapy (TRT), Human Chorionic Gonadotropin (HCG) isn’t just an ajuvant – it’s a vital component for maintaining hormonal health.

If the goal of TRT is to replicate the body’s natural hormone production as closely as possible, then HCG should be considered an essential part of every protocol. I explore this in more detail in a separate article: The Benefits of using HCG with TRT.

What is HCG?

Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone, often dubbed the “pregnancy hormone”, produced by the placenta. In men, it mimics luteinising hormone (LH), acting on Leydig cells in the testes to stimulate testosterone and sperm production.

Types of HCG

• Recombinant hCG (rHCG): DNA-engineered, available in the UK as brands like Ovitrelle. Less practical for TRT due to single-use vial format
• Urinary-derived hCG (uHCG): Purified hCG derived from the urine of pregnant women.

Pharmokokinetics: Absorption & Half-Life

With an average half-life of ~2.3 days⁽¹⁾, HCG reaches stable blood levels in about 10 days.

---

HCG vs LH: Lab Testing Differences

HCG binds to LH receptors but differs enough at the molecular level⁽²⁾ that it’s not detected as LH in hormone blood tests.

---

Administration

Delivered via subcutaneous injection.

---

Unit Measurement

HCG is measured in international units (IU) which is a unit of measurement based on the particular chemical.

---

Storage & Preparation

Powdered hCG can remain at room temperature.

When reconstituting, bacteriostatic saline (not the plain saline it comes with) should be used to maintain sterility. This is essential if multi dosing.

Store in the refrigerator and discard after 30 days due to protein fragility.

Why Use HCG in TRT?

Depending on the volume of bacteriostatic saline you are supplied with, you can using the following as a guide:

1. Prevents Testicular Shrinkage: Maintains testicular volume by continuing natural hormone production.
2. Preserves Fertility: Supports intratesticular testosterone and sperm output while on testosterone therapy.
3. Boosts Libido & Sexual Health: Many men report stronger libido, better erections, and psychological well-being.
4. Eases TRT Transitions: Helps maintain hormonal balance during therapy breaks.

Safety & Side Effects

• Regarded as safe, including urinary-derived forms – no prion transmission risk noted⁽³⁾.
• Possible side effects:
  • Rare: nausea, blood clots, allergic reactions
  • Injection site irritation
  • Hormonal changes (e.g., elevated oestrogen)

Travelling With hCG

HCG is a Schedule 4 Controlled Drug (Class C) in the UK. When travelling:

• Carry a prescription or clinician’s letter detailing:
  • Full name
  • Dosage and quantity
  • Travel dates and destinations
  • Physician’s signature

---

Key Takeaways

• HCG is essential for a comprehensive TRT protocol aiming to replicate natural hormonal balance.
• Clinical evidence supports its use to maintain testicular function, fertility, and sexual health.
• Safe with proper protocols: refrigeration, bacteriostatic saline, lab monitoring, and specialist guidance are essential for good results.
