    How It Works

    HCG binds to the LH receptor in Leydig cells, stimulating intratesticular testosterone production. It maintains testicular volume and supports spermatogenesis during exogenous testosterone administration.

    Quick Start

    • Reconstitution: Add 2.0 mL of bacteriostatic water → 2,500 IU/mL.
    • Typical Range: 250–500 IU 2–3 times weekly.
    • Easy Measurement: At 2,500 IU/mL, 10 units = 250 IU.
    • Storage: 2–8 °C after reconstitution · use within 30 days.

    Reconstitution Steps

    1. Withdraw 2.0 mL of bacteriostatic water.
    2. Inject slowly down the side wall of the vial.
    3. Gently swirl until fully dissolved.
    4. Refrigerate at 2–8 °C · note the date.

    Protocol Overview

    • Goal: Maintain testicular function, support spermatogenesis, prevent atrophy during TRT.
    • Schedule: Continuous use alongside TRT or short PCT cycle.

    Dosing Protocol

    • TRT: 250 IU × 2–3/wk.
    • Fertility: 500 IU × 3/wk.
    • PCT: 1,000–1,500 IU × 3/wk for 2–3 weeks.
    • Break between cycles: For PCT: after 2–3 weeks, pause for 4–6 weeks. On TRT: used continuously alongside—no cycling required.

    Washout & Cycle Restart

    When can I restart?

    For PCT: after 2–3 weeks, pause for 4–6 weeks. On TRT: used continuously alongside—no cycling required.

    Minimum wait period: 4 weeks

    Storage Instructions

    • Lyophilized: 2–8 °C.
    • Reconstituted: 2–8 °C · use within 30 days.

    Important Notes

    • Do not exceed 1,500 IU per dose without medical supervision.
    • Monitor estradiol on high doses.
