Enter the amount you want to measure. The vial buttons will highlight which vial strengths create cleaner syringe-unit measurements.

What amount do you need?

Type the target amount, then choose mg or mcg. Example: 2mg or 500mcg.

Spermatogenesis1,500–3,000 IU SC 2×/wkWith FSH

Label-accurate. The Simeons protocol line correctly carries its 'refuted' label: double-blind trials found no weight-loss effect beyond caloric restriction, and the FDA requires labeling that HCG is not effective for weight loss. The Coviello study showed even 125 IU every other day preserves intratesticular testosterone during steroid suppression.

Possible vial strengths: 5000IU, 10000IU

What Is It?

HCG

Human chorionic gonadotropin reference compound.

Bacteriostatic Water

Sterile water containing a bacteriostatic preservative, commonly used when preparing multi-use research vials.

How To Mix HCG

1
Clean

Use alcohol swabs to clean the tops of both vials.

2
Draw BAC Water

Draw the selected amount of bacteriostatic water.

3
Inject Slowly

Add the liquid slowly down the side of the vial.

4
Swirl Gently

Do not shake. Swirl gently until dissolved.

5
Store Properly

Store as directed and protect from heat and light.

Best Practices & Common Mistakes

Best Practices

  • Use sterile technique.
  • Protect from light and heat.
  • Store refrigerated when appropriate.
  • Use clean syringe-unit math before measuring.

Common Mistakes

  • Confusing milligrams with milliliters.
  • Choosing an option with awkward decimal units.
  • Using too little liquid for very small measurements.
  • Shaking the vial aggressively.

HCG Storage & Handling

Lyophilized Powder: −20°C (−4°F) for long-term storage (up to 24 months). Refrigeration 2–8°C (36–46°F) for short-term use (up to ~3 months). Original sealed vial in the freezer is safest.
Reconstituted Solution: 2–8°C (36–46°F), use within ~7–14 days. Keep sealed, avoid light, and do not repeat freeze-thaw cycles.

Frequently Asked Questions

An HCG calculator usually measures concentration in IU/mL after liquid is added to a vial. The basic math is total IU divided by final liquid volume, not medical dosing or treatment planning.
No. “HCG levels” usually refers to blood or urine hormone levels, often discussed in pregnancy testing. A reconstitution calculator deals with vial concentration, such as how many IU are present per mL after mixing.
Only partly. The calculator can show IU/mL based on vial strength and final liquid volume, but it should not explain injection technique, frequency, treatment use, or personal dosing.
Not exactly. HCG is better described as a glycoprotein hormone, so the calculator should use hormone concentration math, usually IU per mL. Calling it a peptide can confuse the unit system.
The useful inputs are the total IU on the vial and the final amount of liquid in mL. With those two numbers, the calculator can show IU/mL for research or documentation purposes only.
Practical takeaway: If your goal involves weight management, metabolic health, recovery, physical performance, cognitive function, appearance, or general well-being, discuss it with a licensed healthcare professional. They can help you evaluate approved, evidence-based options rather than relying on an unapproved or investigational compound. This calculator is intended only for transparent research-reference calculations and does not determine an appropriate amount, recommend use, or replace professional medical guidance.

About the author

· Pharmacist and Scientific Reviewer

Maria Hrabina is a pharmacist and scientific reviewer with a strong interest in peptide science, pharmacology, and emerging therapeutic compounds.

Her work focuses on understanding how peptide-based compounds interact with biological signaling pathways and how they are being investigated across areas such as metabolic health, dermatology, recovery, regenerative research, and pharmaceutical development.

Maria follows research on a broad range of peptides, from compounds used in approved medicines to experimental molecules still being evaluated in laboratory, preclinical, and clinical studies.

Her approach combines scientific curiosity with critical evaluation of evidence. She believes promising mechanisms and early research deserve attention, but should not be presented as established clinical benefits until they are supported by adequate human data.

Her areas of focus include scientific literature review, mechanisms of action, pharmacology, pharmacokinetics, safety, pharmaceutical formulation, and the overall quality of evidence behind peptide-based compounds.

She is particularly interested in the process of translating an experimental molecule into a reliable pharmaceutical product — including compound characterization, purity, stability, formulation, dose selection, safety assessment, and controlled clinical trials.

Maria believes peptide science has significant long-term potential, but that its progress depends on rigorous research, high manufacturing standards, transparent safety data, and responsible scientific communication.

Through her writing, she aims to help readers understand both sides of peptide research: what makes these compounds scientifically promising and what questions remain before their potential can be considered clinically established.
