Typical Dosage Ranges
FDA-approved dosing for HCG varies by indication. For prepubertal cryptorchidism, referenced regimens include 4,000 USP units three times weekly for three weeks, or 5,000 USP units every second day for four injections. For selected cases of hypogonadotropic hypogonadism in males, 500 to 1,000 USP units three times a week for three weeks is referenced, followed by the same dose twice a week for three weeks. In non-medical bodybuilding contexts, HCG is commonly referenced at 250–500 IU every other day or 2–3 times per week, though such use falls outside approved indications and lacks FDA-approved human dosing data.

Reconstitution & Handling
HCG is supplied as a lyophilized powder requiring reconstitution with bacteriostatic water for injection. The recommended diluent is Bacteriostatic Water for Injection preserved with 0.9% benzyl alcohol. After reconstitution, the solution should be refrigerated and used within 30 days. Reconstitution should be performed gently by swirling rather than shaking to prevent denaturation.
For a 5,000 IU vial, reconstitution with 1 mL of diluent yields a concentration of 5,000 IU/mL. Reconstitution with 10 mL yields a concentration of 500 IU/mL for multiple-dose administration. The appropriate reconstitution volume depends on the intended dosing strategy.
Managing Side Effects
Reported adverse reactions with HCG include headache, irritability, restlessness, depression, fatigue, edema, precocious puberty, gynecomastia, and pain at the injection site. Hypersensitivity reactions both localized and systemic have been reported, including erythema, urticaria, rash, angioedema, and dyspnea.
In women undergoing ovulation induction with HCG and menotropins, the principal serious adverse reactions include ovarian hyperstimulation syndrome, rupture of ovarian cysts with hemoperitoneum, multiple births, and arterial thromboembolism. HCG should be used with caution in patients with cardiac or renal disease, epilepsy, migraine, or asthma due to potential fluid retention.
Post-Cycle Considerations
HCG is not a standard component of post-cycle therapy. In non-medical bodybuilding contexts, some references suggest HCG may be used during a cycle or in the weeks immediately following the last testosterone injection, prior to starting SERM-based PCT. However, this use is not FDA-approved and lacks clinical validation. Agents such as Clomid or Tamoxifen are more commonly referenced for PCT purposes.
