How much creatine to take before the drug test

PMID: 3013406 DOI: 10.1s3400072

Creatine helps to pass a drug test by restoring the creatinine level in the urine. Creatinine levels will be checked during the drug test.

If it is out of the normal range, your sample will be rejected and you’ll have to retake the test.

We’ll tell you why you even need to restore creatinine levels and give you instructions on how to take creatine.

Why do I need to raise creatinine levels?

If you are trying to pass the test using the flushing/dilution method, then you need to drink a lot of water.

Drinking water will make you pee frequently and flush THC from your bladder. But it will flush all other components of the urine too. So your urine will be diluted.

The lab technician will reject such a sample. This is why you need to restore the creatinine level and other urine parameters.


  • Take 10 grams of creatine ethyl ester 3 hours before the test


  • Take 10 grams of creatine monohydrate 12 hours before the test.

Creatine ethyl ester vs monohydrate

The difference between these two types of creatine is that creatine ethyl ester is actually less stable than creatine monohydrate and is converted into the waste product creatinine at a much faster rate.

Creatine monohydrate, on the other hand, has a bio-availability of nearly 100%, meaning that the body will absorb pretty much all of it.

But the main purpose of taking creatine in our case is to raise the creatinine levels. So if you are short on time, use ethyl ester.

Can you use natural sources of creatine?

Creatine can be derived from a wide variety of natural sources.

Foods rich in creatine include red meat, salmon, beef, lean meat, tuna, poultry, legumes, dairy products (milk, cheese), pumpkin, sesame, walnuts, pine nuts, almond, beans, pea, seaweed, pistachio, spirulina, spinach, watercress, eggs, tofu, Brazil nuts, quinoa, white beans, etc.

The levels of creatinine in the urine can also be increased via exercise. Mild jogging, hiking, swimming, cycling, or any other cardio exercises will aid the body’s utilization of the available creatine and metabolize it into creatinine.

So it may sound logical that eating high creatine food and exercising will help to keep normal creatinine levels in the urine while trying to pass the test.

That’s partly true. You can raise creatinine to high levels by eating food with high creatine content and exercising. Then, when you’ll be using the flushing method, creatinine levels will drop to normal values.

But you should track the levels of creatinine with the test strips to make sure they are high enough before the drug test.

Why is creatine in drinks for a drug test

During the drug test, the first what will be checked are the basic urine parameters (pH, creatinine levels, urine color, specific gravity)

The reason for this is to determine if you tried to manipulate the results of the test. So if any of these basic parameters are not within the accepted range the sample won’t be accepted.

This is how most amateurs who just gulp lots of water to dilute their samples before going for a test get caught. The water won’t just flush out unwanted metabolites.

Other key parameters checked for will also be changed. Thus any lab technician with a brain will figure out what you’ve been up to.

All methods of passing drug tests entail the consumption of lots of water. And as mentioned earlier, one of the basic parameters checked for during a drug test is the level of creatinine in the urine.

Consuming lots of water reduces specific gravity and dilutes your creatinine levels, Hence, it is imperative that before you just gulp lots of water to flush out metabolites, run a test to know the level of creatinine in your urine.

How to track your creatinine levels

Creatinine levels are determined by muscle mass, so someone with more muscles is expected to possess higher levels of creatinine. Another factor that impacts creatinine levels is gender.

The average creatinine level in males is between 0.6mg/dl and 1.2mg/dl, while in females is between 0.5mg/dl and 1.1mg/ml

So you need to get some urine test strips and track the creatinine levels before the drug test.

The best option is to test the flushing method using urine test strips and a home drug test. Doing such dry runs will help you to estimate the exact amount of water and creatine required to pass the test with confidence.
