HMG Hormone

1. Product Nature

HMG (Human Menopausal Gonadotropin) is a natural hormone preparation extracted from the urine of postmenopausal women, containing two key components:

FSH (Follicle-Stimulating Hormone)

LH (Luteinizing Hormone)
75IU indicates that each vial contains 75 International Units (standard ratio FSH:LH = 1:1) and requires subcutaneous or intramuscular injection.

2. Primary Medical Uses

For Men: Treatment of hypogonadotropic hypogonadism (HH) leading to oligospermia/azoospermia.

For Women: Ovulation induction (IVF or polycystic ovary syndrome treatment).

3. Potential Fitness Applications and Benefits

(1) Possible Uses for Male Athletes

Testicular Function Recovery:

Useful for testicular atrophy caused by long-term steroid use. HMG's FSH stimulates sperm production, while LH supports testosterone secretion (more effective when combined with HCG).

Compared to HCG: HCG mimics only LH, whereas HMG contains both FSH and LH, offering more comprehensive spermatogenic recovery.

Mild Testosterone Boost:

LH stimulates testosterone production, though weaker than direct testosterone or HCG use. May assist in PCT (Post-Cycle Therapy).

(2) Theoretical Advantages (Limited Evidence)

Preserves Fertility:

Long-term steroid use may cause infertility; HMG+HCG combinations are used in reproductive medicine to restore sperm quality.

Reduces Gonadal Suppression:

Low-dose HMG (e.g., 75IU twice weekly) during steroid cycles may mitigate hypothalamic-pituitary-gonadal (HPG) axis suppression.

4. Practical Limitations

High Cost, Limited Efficacy:

Testosterone-boosting effects are far weaker than direct testosterone or HCG use, requiring prolonged administration (typically 3-6 months for results).

Side Effect Risks:

Men: Elevated estrogen (requiring AI like anastrozole), testicular discomfort.

Women (Absolute Contraindication): Risk of ovarian hyperstimulation (OHSS) unless used for medical ovulation induction.

Non-Standard in Fitness:

HCG or SERMs (e.g., tamoxifen) are preferred for PCT; HMG is reserved for severe spermatogenic impairment.

5. Typical Fitness-Related Protocols

Post-Steroid Spermatogenesis Recovery:

HMG 75IU 3x weekly + HCG 500IU 2x weekly (minimum 12 weeks).

Controversial PCT Adjuvant:

HMG 75IU 2x weekly + Tamoxifen 20mg/day (lacks robust clinical support).
