πŸ’‰ HCG (Human Chorionic Gonadotropin): The Multifunctional Hormone for Hormone Balance, Fertility & Fat Loss

HCG, or Human Chorionic Gonadotropin, is a naturally occurring peptide hormone best known for its roles in fertility support, hormone regulation, and weight management. First identified in early pregnancy, HCG is now widely used in medical protocols for men and women, as well as in performance and hormone therapy research.

Whether the goal is testosterone preservation, ovulation support, or body recomposition, HCG has a wide range of potential uses supported by decades of clinical evidence.


🧬 What Is HCG?

HCG is a glycoprotein hormone produced in large amounts during early pregnancy to maintain progesterone levels and support embryo implantation. However, outside of pregnancy, HCG has become a valuable hormone therapy tool, particularly for:

  • Men on testosterone replacement therapy (TRT)
  • Women with ovulatory or fertility issues
  • Bodybuilders seeking post-cycle therapy (PCT)
  • Fat loss protocols like the HCG Diet

HCG works similarly to luteinizing hormone (LH), signaling the gonads (testes or ovaries) to produce more testosterone, estrogen, and progesterone.


βœ… Top Clinical Uses & Benefits of HCG

πŸ§” Male Hormone Support & TRT Enhancement

  • Preserves natural testosterone production during TRT
  • Prevents testicular shrinkage and maintains fertility
  • Often used in post-cycle therapy (PCT) to help the body resume endogenous testosterone production after anabolic steroid use

πŸ‘© Female Fertility & Ovulation Induction

  • Used to trigger ovulation in women undergoing fertility treatments (e.g. IVF or IUI)
  • Supports progesterone levels in the luteal phase of the cycle

βš–οΈ Weight Loss & Metabolism (HCG Diet)

  • Originally popularized by Dr. Simeons, the HCG Diet pairs low-dose HCG with a very low-calorie diet (VLCD) for rapid fat loss
  • Claims include reduced hunger, fat targeting, and preservation of lean muscle mass

⚠️ Note: The HCG Diet is controversial and not FDA-approved. Research use only.


πŸ”¬ How Does HCG Work?

  • In men, HCG mimics LH, stimulating Leydig cells in the testes to produce testosterone
  • In women, HCG mimics LH to cause follicular rupture and egg release
  • May also modulate metabolism and support fat-burning pathways through indirect hormonal mechanisms

πŸ’‘ Typical Research Use Guidelines

  • Form: Lyophilized powder, reconstituted with bacteriostatic water
  • Dose for TRT support (men): 250–500 IU 2–3x per week (research-based protocols)
  • Dose for fertility (women): 5,000–10,000 IU one-time injection during ovulatory cycle
  • Dose for HCG Diet: 125–200 IU daily with calorie restriction (research only)

⚠️ Important: HCG is a prescription drug in many countries and should only be used under medical supervision or for approved research purposes.

πŸš€ Conclusion: Is HCG Still Relevant in Modern Peptide Therapy?

Yes. Despite newer options emerging in hormone and peptide therapy, HCG remains a gold-standard tool for:

  • Preserving natural testosterone
  • Supporting fertility
  • Facilitating fat loss in structured protocols

Whether used in a TRT protocol, PCT regimen, or reproductive support plan, HCG is a versatile hormone that plays a critical role in maintaining hormonal balance and physiological integrity.
