Ingredients Label

Active Ingredients

Chromium

Chromium is a mineral that’s been shown to assist with fat-loss.

This happens primarily through its abilities to regulate blood sugar levels and blunt hunger (1, 2).

An effective dose is about 500-1,000 micrograms.

Caffeine

The popular stimulant caffeine is well-known for improving energy levels, but can also boost metabolic rate.

This means your body can burn off extra body fat, even at rest (3).

The effective dose for fat-burning is usually around 200g.

Theacrine

Theacrine is another stimulant, which is similar in structure and function to caffeine (4).

It is thought to be quicker-releasing than caffeine, but shorter-lasting.

Theanine

Theanine is an amino acid with calming effects.

Research shows that it’s effective for increasing relaxation and focus, and is often combined with caffeine to reduce jitters or anxiety (5).

The effective dose is about 100-200mg.

CLA

Conjugated linoleic acid, or CLA, is a fatty-acid which may aid with fat-loss.

Studies have found its fat-burning effects to be small and unreliable, but it may be quite effective for increasing lean body mass (6, 7).

The effective dose is 3-6g daily, taken with meals.

MCTs

MCT stands for medium chain triglyceride.

It’s a type of fat which can be found naturally in coconut oil.

Although it’s a fat itself, it has been shown to promote the loss of body-fat, and may also suppress appetite (8).

Who Takes It?

Athletes wanting to boost their energy levels and fat-loss while dieting may benefit from using SST.

How to Take

Take 1 serving (2 capsules) in the morning, on an empty stomach.

Side Effects

The stimulants in SST could trigger rapid or irregular heartbeat in those who are stimulant-sensitive.

Pros

Stimulants improve energy and metabolic rate
May blunt hunger
Includes black pepper extract to improve absorption of the other ingredients.

Cons

Some ingredients aren’t all that effective, and some are included in very small doses
Could include more fat-burning ingredients.

Conclusion

SST may look like a very potent, clinical fat-burner, but it may fall very short of expectations.

It contains a strong dose of stimulants which will boost your energy and metabolic rate, but aside from this it doesn’t include many reliable fat-burning ingredients.

Doses of virtually all the other ingredients are well below their clinically-effective doses, and will have minimal effects, if any.
