2DG Dosage: A Practical Guide for Everyone

2-Deoxy-D-glucose (2DG) is usually taken orally, but in clinical settings, it may also be administered intravenously or through metronomic dosing devices, similar to an insulin pump.

The concept of 2-DG is intriguingly simple: “Cheat the Cheater.” Imagine tackling cancer with a strategy as cunning as it is simple: starving the disease without starving yourself.

This innovative approach targets cancer’s insatiable craving for glucose by masquerading as the very sugar it desires. Cancer cells, fooled by this clever disguise, eagerly absorb it, only to find their growth stopped.

This versatile treatment can support you on your journey, whether you use it as a:

This tool offers detailed instructions on how to use 2-deoxy-glucose for your daily needs and provides information for using 2DG as a standalone treatment or in combination with other therapies.

Additionally, it offers a downloadable treatment plan that you can conveniently display in your home or save on your mobile device or computer.

Convenient Oral Administration and Dosage

Most people worldwide prefer taking 2DG orally due to its convenience. The powder form of 2DG is dissolved in 100-250 mL of potable water, adjusted for body weight. This method allows for easy administration at home or anywhere with access to a glass of water.

Taking 2DG is straightforward and convenient. For quick and accurate dosing, use a pre-measured scoop available from some of the suppliers, or measure the powder with a digital pocket scale or kitchen scale. Mix the 2DG powder with 100-250 ml of room-temperature water to ensure proper dilution and effectiveness.

To take your 2DG, start by dissolving the desired amount of 2-deoxy-glucose in room-temperature water. First, calculate your daily morning and evening doses. Use a digital scale that measures to at least a tenth of a gram (0.1g) to weigh the powder accurately. Place the measured powder in a cup and dissolve it in room-temperature water.

Your 2DG solution is ready for use. If you can’t take it immediately, store the solution in a cool, dark place to avoid direct sunlight until you are ready to drink it. It’s a good idea to stir the solution just before drinking to ensure that the 2DG is fully dissolved and evenly distributed.

For optimal results, the recommended daily dosage of 2-Deoxy-Glucose (2DG) is 30 mg/kg (13.6 mg/lb) of body weight), split into two doses. Take 20 mg/kg in the morning after an overnight fast, and 10 mg/kg in the evening, at least three hours after your last meal. The morning dose should make up 66% of the total calculated dose, while the evening dose should account for the remaining 34%.

Fasting and Dosing Schedule

For optimal effectiveness, 2DG should be taken on an empty stomach. Patients are advised to fast overnight (except for clear fluids) for at least six hours before the morning dose. The evening dose should be taken no sooner than 12 hours after the morning dose, with at least three hours of fasting before the evening administration.

Each oral dose of 2DG should ideally be taken one hour before any meal. It is important to avoid taking 2DG within three hours after strenuous exercise, as exercise can cause the body to deplete calories and absorb 2DG into muscles instead of targeting the cancer cells.

Dosing Cycle

2DG is typically taken on a daily schedule, twice daily, for a week (Monday to Sunday) in an intermittent pattern. This involves a cycle of seven days on, followed by seven days off. This intermittent approach ensures optimal efficacy.

You should continue taking 2DG alongside other treatments until you achieve sustained positive progress and remission.

2DG Protocols for Optimal Cancer Treatment

Taking 2DG as part of your cancer treatment involves a structured schedule for maximum effectiveness.

Stand-Alone 2DG Treatment

For single treatment, take 2DG for 7 days, followed by a 7-day break, and repeat until remission. Regular follow-up scans and tumor marker tests every 3-6 months are essential to monitor your situation.

Preventing Cancer Recurrence After Achieving No Evidence of Disease

To prevent recurrence after achieving No Evidence of Disease (NED) for at least 5 years, follow the same 7-day on, 7-day off schedule and maintain regular check-ups.

2DG and Other Alternative Treatments

When combining 2DG with other alternative treatments, continue following the 7-day cycle as prescribed, without the need to alter your regular dosing schedule. Use all of the information provided in the calculator.

2DG and Chemotherapy

If you are undergoing chemotherapy, pause 2DG 7 days before beginning your treatment. Resume taking it 24 hours after finishing your chemotherapy session, continuing for at least 7 days before taking a break. After completing chemotherapy, continue taking 2DG to maintain remission or further reduce cancer until you achieve NED.

2DG Alongside Immunotherapy and Targeted Therapy

For immunotherapy, discontinue 2DG 2 days before starting your treatment and resume 24 hours after the final dose of immunotherapy medication. Take 2DG for 7 days, followed by a 7-day break, and continue 2DG until you attain positive progress.

2DG and Radiotherapy

Continue taking 2DG according to your usual ‘Single Treatment’ schedule until one week before your planned radiotherapy, then pause for one week. Once radiotherapy begins, take 2DG 60-120 minutes after each session from Monday to Friday, with a break on weekends, and continue this until your radiotherapy course is complete.

After completing radiotherapy, switch back to the ‘Single Treatment’ schedule, maintaining the 7-day on, 7-day off pattern until you achieve No Evidence of Disease (NED).

2DG and Surgery

Before surgery, begin the 7-day on, 7-day off cycle as soon as the procedure is scheduled, and discontinue 2DG two days before the surgery. After your operation, resume 2DG four weeks after hospital discharge, and continue the treatment until full remission is confirmed.

Effective Monitoring and Discontinuing 2DG in Successful Cancer Treatment

Regular monitoring through follow-up scans and tumor marker tests every 3-6 months will help ensure the treatment’s effectiveness.

While taking 2DG, regular blood tests and imaging scans are essential to monitor the treatment’s effectiveness. We recommend having the following tests every 2-6 months: a complete blood count (CBC), a basic metabolic panel, and tumor marker tests.

These biomarkers can help track the progress of your therapy, indicating changes in cancer levels. Additionally, it is beneficial to undergo a CT scan or MRI at least once in half a year, with sonography as an alternative, to observe any size changes in the tumor. This comprehensive monitoring ensures you stay informed about your treatment’s impact.

If you remain cancer-free for 5 years, you can stop taking 2DG.

Important Notes for Using 2DG with Diabetes or Chronic Kidney Disease

If you have diabetes, it is advisable to test your blood sugar levels before taking 2DG to ensure safety and effectiveness.

Patients with chronic kidney disease stage 3 or higher should monitor their creatine levels either avoiding 2DG or reducing the dose by 50% to ensure safety and efficacy. Due to reduced kidney function, 2DG is eliminated more slowly from the body, necessitating a dosage reduction for safe and effective treatment.

By following these guidelines, you can effectively incorporate 2DG into your routine while ensuring its maximum benefits.
