HCG Dosage & Reconstitution Guide

Research and educational use only — not medical advice, and not for human consumption. The figures below are summarized from public sources, product labeling, and community reports, and are not a prescription or a substitute for a qualified clinician.

Typical dose
250 IU
Route
Subcutaneous injection
Frequency
2–3 injections weekly
After mixing
2500 IU/mL

Reconstitution

HCG ships as a freeze-dried (lyophilized) powder that has to be mixed with bacteriostatic water before use. Draw 2 mL of bacteriostatic water into a syringe and add it to a 5000 IU vial, letting the stream run down the inside wall of the glass rather than blasting the powder directly. Swirl gently — never shake — until the solution is clear, then keep it refrigerated.

Worked example. 2 mL into a 5000 IU vial gives a concentration of 2500 IU/mL. A 500 IU dose then works out to 0.2 mL = 20 units on a U-100 insulin syringe. Scale the water volume up or down to make your target dose land on an easy-to-read mark (1 unit = 0.01 mL).

  1. Wipe both vial stoppers (peptide and bacteriostatic water) with an alcohol swab and let them dry.
  2. Draw 2 mL of bacteriostatic water into a syringe.
  3. Inject it slowly against the inside wall of the peptide vial.
  4. Swirl gently until fully dissolved; do not shake.
  5. Label the vial with the contents, concentration, and date, and store it in the refrigerator.

Dosing schedule

Phase Dose Volume Insulin units (U-100) Notes
TRT support 250 IU 0.1 mL 10 units 2–3× weekly
Standard 500 IU 0.2 mL 20 units 2–3× weekly
Fertility protocols 1000 IU 0.4 mL 40 units 2–3× weekly, clinician-guided

Timing & cycling

Spread evenly (e.g. Mon/Wed/Fri). Subcutaneous with an insulin syringe is standard now; IM works too.

Cycle length. Runs alongside TRT continuously, or in short blocks for fertility/recovery protocols under bloodwork.

Storage & handling

Keep the lyophilized (unmixed) vial refrigerated at 2–8 °C (36–46 °F) in a dry, dark place — it tolerates short periods at room temperature during shipping. Once reconstituted, store it at 2–8 °C, never frozen, and use it within about 2–4 weeks (sooner if the solution turns cloudy or discolored). Swab the stopper before every draw and use a fresh needle each time.

Supplies you'll need

  • HCG vials — about 5 for an 8-week run at the upper dose
  • Bacteriostatic water — 2 mL per vial (a 10–30 mL multi-dose bottle covers several vials)
  • U-100 insulin syringes (0.3–0.5 mL / 30–50 unit barrels are easiest to read) — roughly 24 for 8 weeks, plus spares
  • Alcohol swabs — one per injection and one per vial draw
  • Sharps container for safe needle disposal

Key points

  • Dosed in International Units, not mg — reconstitution math runs on IU/mL.
  • Reconstituted hCG is less stable than most peptides: refrigerate and use within ~30 days, sooner if it turns cloudy.

What to monitor

Testosterone and estradiol — hCG raises both; estrogen-type sides (moodiness, nipple sensitivity) mean the dose or aromatization needs attention.

Legal & prescription status

Yes. This is an FDA-approved prescription medication (human chorionic gonadotropin (brands such as Pregnyl, Novarel)), so a legitimate, human-grade version is available only through a licensed prescriber and pharmacy. The lookalike 'research chemical' versions sold online are unapproved, not quality-controlled, and labelled 'not for human consumption.'
