How should I take SIRE Testosterone Support?2023-02-10T15:30:21+08:00

Oral use. The recommended dose is 2 capsules in the morning and 2 capsules in the evening. Best taken with food.

What is testosterone?2023-02-10T15:30:21+08:00

Testosterone is the major sex hormone in males and is most associated with sex drive and sperm production. 

It also plays an important role in bone and muscle health and mood. 

What causes low testosterone levels?2023-02-10T15:30:21+08:00

The most common cause is aging. As men age, testosterone levels drop very gradually, about 1-2% each year after the age of 30. 

However, there are other factors such as genetic conditions, alcohol abuse, chronic health conditions (e.g. kidney disease) or certain medical treatments (e.g. chemotherapy) that can contribute to low testosterone levels.

How will I know if I have low testosterone?2023-02-10T15:30:21+08:00

Some symptoms include reduced sex drive, erectile dysfunction, low mood, lower energy levels and loss of armpit and pubic hair. If you suspect you might have low testosterone, you should consult a doctor. 

Here at SIRE, we offer a simple blood test to check your testosterone levels.

Can I take more than 4 capsules a day?2023-02-10T15:30:20+08:00

It is not recommended to do so as it may increase the risk of experiencing side effects. Always speak to your doctor for advice.

What are the possible side effects?2023-02-10T15:30:20+08:00

Possible side effects may include mild digestive upset, including nausea or stomach cramps. If this happens to you, try taking smaller doses of the supplement throughout the day and see if it helps.

Some other side effects may include restlessness and insomnia. We suggest taking the second dose earlier in the evening. Avoid taking the supplement before bedtime. 

If you are experiencing any serious side effects or have a side effect that is bothersome to you, stop taking the supplement immediately and consult our doctor for an evaluation.

Who should not take SIRE Testosterone Support?2023-02-10T15:30:20+08:00

SIRE Testosterone Support is contraindicated in people with a known hypersensitivity to any ingredient of the product.

Use with caution in patients with a recent heart attack.

Use in caution in patients with renal impairment.

Use with caution in patients with seizure disorders or in those at risk of seizures.

Avoid in people with guanidinoacetate methyltransferase deficiency (GAMT). People with this inherited condition are unable to convert arginine and other similar chemicals into creatine. To prevent complications from this condition, avoid L-arginine supplements.

Keep out of the reach of children.

Will my body still be able to produce testosterone on its own if I stop taking SIRE Testosterone Support?2023-02-10T15:30:20+08:00

Yes. SIRE Testosterone Support is not a testosterone replacement therapy which directly introduces the hormone to your body. Instead, it contains a blend of ingredients that aim to support your body’s natural production of testosterone. This means that SIRE Testosterone Support does not suppress your body’s ability to produce testosterone in any way.

Is SIRE Testosterone Support vegetarian?2023-02-27T09:53:25+08:00

No, certain ingredients are from animal origins. If you require details or would like to indicate interest for a vegetarian option, please write in to us here.

How long does SIRE Testosterone Support take to work?2023-02-10T15:30:19+08:00

As with all supplements, it takes time to understand how your body reacts to it. We would recommend taking it regularly for a trial period of 1-3 months to assess whether you feel any real benefits.

Can I use SIRE Testosterone Support with PDE-5 inhibitors (e.g. Viagra)?2023-02-10T15:30:48+08:00

Yes, we formulated SIRE Testosterone Support as a possible complement to PDE-5 inhibitors like Viagra. 

Ingredients were carefully selected based on a comprehensive set of considerations. One such consideration is the availability of evidence supporting an improvement in ED symptoms. 

Available studies support best results when supplements are taken together with medications and lifestyle changes. Always speak to your doctor for advice.

Can I use SIRE Testosterone Support with other medications?2023-02-10T15:31:10+08:00

SIRE Testosterone Support may lower blood pressure, blood sugar and may slow blood clotting.

If you are on medications for blood pressure, blood sugar and/or blood clotting, it is advisable to speak to your doctor before starting on this supplement. 

SIRE Testosterone Support may affect the absorption of certain antibiotics such as quinolone and tetracycline antibiotics. This can be managed by spacing the antibiotics apart from the supplement. Always speak to your doctor if you are taking antibiotics with this supplement.
