Creatine hydrochloride is a form of creatine, a compound that supports muscle strength and athletic performance. The product is also formulated with vegetarian capsule shells and titanium dioxide as inactive ingredients.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Muscle strength, power, and sports performance.
  • We looked for evidence on: Athletic performance, Muscle strength, Physical performance, Muscle breakdown, Postoperative recovery, Sarcopenia — and 4 related terms.
  • The strongest evidence on file: Creatine is rated "Possibly Effective" for Athletic performance (Natural Medicines).
  • Also on file: Creatine is rated "Possibly Effective" for Muscle strength, Sarcopenia.
  • Also on file: Fenugreek is rated "Insufficient Reliable Evidence To Rate" for Athletic performance, Muscle strength.

The fenugreek extract in this product is rated Possibly Effective for sexual dysfunction and sexual arousal, and Possibly Effective for dysmenorrhea and diabetes support based on available evidence. Creatine hydrochloride is rated Possibly Effective for muscle strength and athletic performance, and Possibly Effective for sarcopenia (age-related muscle loss) and cerebral creatine deficiency syndromes.

It is rated Possibly Ineffective for Huntington disease and osteopenia.

The evidence, ingredient by ingredient Fenugreek Creatine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Fenugreek is generally well tolerated in food amounts, but supplement doses may cause side effects. The most common are abdominal pain, bloating, diarrhea, indigestion, gas, low blood sugar (hypoglycemia), and nausea.

Rare serious allergic reactions including swelling (angioedema), airway constriction (bronchospasm), and shock have been reported. Fenugreek may affect the uterus and should be avoided during pregnancy.

If fenugreek reaches a baby through breast milk or prenatal exposure, it can cause an unusual body odor that might be mistaken for maple syrup urine disease, though this doesn't appear to cause long-term harm. Creatine is generally well tolerated in healthy adults.

Common side effects are dehydration, diarrhea, stomach upset, muscle cramps, and water retention. Rare serious effects include kidney inflammation, kidney failure, severe muscle breakdown (rhabdomyolysis), and blood clots.

People with kidney problems should be cautious. Safety in pregnancy has not been established, so it's best avoided; there also isn't enough safety information for nursing mothers.

Testofen Fenugreek seed extract9 drug types · 389 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, fenugreek might have additive effects when used with anticoagulant or antiplatelet drugs.
Some of the constituents in fenugreek have antiplatelet effects in animal and in vitro research. However, common fenugreek products might not contain sufficient concentrations of these constituents for clinical effects. A clinical study in patients with coronary artery disease or diabetes shows that taking fenugreek seed powder 2.5 grams twice daily for 3 months does not affect platelet aggregation, fibrinolytic activity, or fibrinogen levels .

Likelihood Unlikely Evidence B
Antidiabetes Drugs

Theoretically, fenugreek seed might have additive hypoglycemic effects when used with antidiabetes drugs.
Clinical research shows that fenugreek seed can reduce fasting blood glucose and 2-hour postprandial glucose levels in adults with type 2 diabetes.

Likelihood Probable Evidence B
Clopidogrel (Plavix)

Theoretically, fenugreek seed might alter the clinical effects of clopidogrel by inhibiting its conversion to the active form.
Animal research shows that fenugreek seed 200 mg/kg daily for 14 days increases the maximum serum concentration of clopidogrel by 21%. It is unclear how this affects the pharmacokinetics of the active metabolite of clopidogrel; however, this study found that concomitant use of fenugreek seed and clopidogrel prolonged bleeding time by an additional 11%.

Likelihood Possible Evidence D
Metoprolol (Toprol)

Theoretically, fenugreek seed might have additive hypotensive effects when used with metoprolol.
Animal research shows that fenugreek seed 300 mg/kg daily for 2 weeks decreases systolic and diastolic blood pressure by 9% and 11%, respectively, when administered alone, and by 15% and 22%, respectively, when given with metoprolol 10 mg/kg.

Likelihood Probable Evidence B
Phenytoin (Dilantin)

Theoretically, fenugreek might decrease plasma levels of phenytoin.
Animal research shows that taking fenugreek seeds for 1 week decreases maximum concentrations and the area under the curve of a single dose of phenytoin by 44% and 72%, respectively. This seems to be related to increased clearance. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Sildenafil (Viagra)

Theoretically, concurrent use of sildenafil and fenugreek might reduce levels and therapeutic effects of sildenafil.
Animal research shows that taking fenugreek seeds for 1 week reduces maximum concentrations and the area under the curve of a single dose of sildenafil by 27% and 48%, respectively. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Theophylline

Theoretically, fenugreek may reduce the levels and clinical effects of theophylline.
Animal research shows that fenugreek 50 grams daily for 7 days reduces the maximum serum concentration (Cmax) of theophylline by 28% and the area under the plasma drug concentration-time curve (AUC) by 22%.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, fenugreek might have additive effects with warfarin and increase the international normalized ratio (INR).
Some fenugreek constituents have antiplatelet effects, although these might not be present in concentrations that are clinically significant. In one case report, a patient taking warfarin experienced an increased INR when starting to take fenugreek in combination with boldo.

Likelihood Possible Evidence D
Antihypertensive Drugs

Fenugreek may also have an additive effect on blood pressure-lowering medications. Studies on animals have shown that fenugreek seed can decrease both systolic and diastolic blood pressure by up to 22% when combined with metoprolol. Therefore, it is essential to monitor your blood pressure regularly if you are taking fenugreek and metoprolol together or any other antihypertensive drugs.

Con-Cret + Test by CON-CRET: Common Questions

Does Con-Cret + Test by CON-CRET interact with any medications?
Yes. Based on its ingredients, Con-Cret + Test has a known interaction with 389 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Con-Cret + Test contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is fenugreek safe during pregnancy?
No. Supplement amounts of fenugreek may affect the uterus, so medicinal use is advised against during pregnancy. If a baby is exposed to fenugreek during pregnancy or through breast milk, it can cause an unusual body odor—though this doesn't appear to cause lasting harm. Talk with your doctor before use if you're pregnant or planning to become pregnant.
Can I take this product while breastfeeding?
Fenugreek is often used to boost milk supply, but the evidence is limited and you should discuss it with your provider first. Creatine safety information for nursing mothers is not established, so it's best avoided. Contact your doctor or pharmacist for personalized guidance on both ingredients.
What side effects might fenugreek cause?
The most common are abdominal pain, bloating, diarrhea, indigestion, gas, low blood sugar, and nausea. Rare serious allergic reactions—including swelling of the throat, airway constriction, and shock—have been reported. If you experience signs of an allergic reaction, seek immediate medical help.
What side effects might creatine cause?
Common side effects are dehydration, diarrhea, stomach upset, muscle cramps, and water retention. Rare serious effects include kidney problems and severe muscle breakdown. If you have kidney disease or concerns, talk to your pharmacist before taking this product.
Does fenugreek actually help with sexual function?
Fenugreek extract is rated Possibly Effective for sexual dysfunction and sexual arousal based on available evidence. This means some research supports its use, but the evidence is not conclusive. Results vary between individuals.
Does creatine really improve muscle strength and athletic performance?
Creatine is rated Possibly Effective for muscle strength and athletic performance. The evidence supports its use in these areas, though results will vary depending on your training, diet, and other factors.
