Research Protocol & Dosage
Source-reported examples · not treatment recommendations
- Amount
- 500 IU per administration; separate high-dose examples use 1,500–2,500 IU
- Frequency
- Three times weekly
- Cycle / observation period
- 8–16 weeks
- Route / research model

IU denotes biological activity, not syringe markings. Indication-specific prescribing and monitoring cannot be inferred from these examples.
Titration & progression
A dose range is not a titration schedule. No independently verified stepwise escalation has been established for this source-reported regimen.
Supply & Planning
Compare vial strengths here. A different vial size changes the available material, not the biological dose.
Diluent & formulation
Diluent compatibility is formulation-specific. A verified manufacturer instruction is still needed before bacteriostatic water or another diluent can be listed as suitable for this research material.

Material minimum only: round total material ÷ vial content up to a whole vial. Actual supply may be higher because of single-use packaging, discard dates, dead space or losses. No validated multi-use storage period is assumed.
Reported Research Results
Selected observations from the cited research. Each finding retains its study population, formulation and limitations.
- Coviello and colleagues randomized 29 men with normal reproductive physiology to testosterone plus placebo or different HCG exposures for three weeks. They measured intratesticular testosterone using testicular-fluid samples. HCG maintained this local hormone measurement in a dose-dependent fashion despite suppression of circulating gonadotropins. The study did not establish a pregnancy rate or validate a universal fertility-preservation protocol. [1]
- An older study followed 18 males with hypogonadotrophic hypogonadism during combined HCG and HMG treatment. Hormonal and semen responses differed substantially between those with isolated gonadotropin deficiency and those who had undergone hypophysectomy. Improvements in sperm measures did not translate uniformly into fertility; the authors reported fertility in three participants. [2]
- They are distinct interventions in the cited combination study. Do not treat the study as evidence that their names, actions or clinical roles are interchangeable. [2]
