"175 mg caffeine provides energy and focus"
Clinical trials use 200mg; 175mg is slightly below but still produces measurable improvements in strength and alertness.
PubMed: caffeine performance meta-analysis -
"3g creatine monohydrate improves strength"
3g is part of the standard 3-5g daily maintenance dose. Clinical trials confirm strength and power gains at this dose.
PubMed: creatine monohydrate strength studies -
"Beta-alanine supports endurance performance"
1.6g per serving is only 1/3 of the 4.8-12g daily dose used in clinical trials. Requires multiple servings daily to be effective.
-
"Proprietary blend formula"
Supporting ingredient doses are hidden; impossible to verify if they're therapeutic or just filler at token amounts.
Consumer advice
Check the label for the full ingredient list and verify you're not sensitive to beta-alanine (causes harmless tingling). If you're new to pre-workouts, start with one scoop to assess tolerance. Consider buying creatine, caffeine, and beta-alanine separately if budget is tight—you'll get the same effects for less money. This product is legitimate, but you're paying a brand premium.

Why the chain breaks for this product
Most ingredients below have real research behind them. The problem isn't the ingredients — it's the doses. 8 of 14 are hidden inside a proprietary blend, so the product can claim the benefits without delivering the chain that gets you there.
Caffeine
Stimulant that boosts exercise power, fat burning during workouts, and may reduce migraine risk with habitual use.
Research-backed dose: 3-6 mg/kg body weight daily based on study doses
In this product: Dose not disclosed
Well-researched sports supplement that boosts explosive power, sprint performance, and muscle mass.
Research-backed dose: 3-20g daily (3-5g maintenance; 20g/day loading phase)

In this product: 12.5 mcg
Thiamin (as Thiamin Hydrochloride)
Essential minerals that regulate hydration, nerve function, and muscle contraction. Critical for recovery after heavy exercise.

Safety & side effects
What NIH says about the ingredients in this product. This describes the ingredients, not tests of this product, and it is not medical advice. Ask a doctor or pharmacist first if you take medication, are pregnant or nursing, or have a health condition.
Vitamin D
Vitamin D toxicity is almost always caused by excessive supplement intake. It can raise blood calcium and, in extreme cases, lead to kidney failure and death. The adult upper limit is 100 mcg (4,000 IU) a day.
Possible side effects
- High blood calcium from vitamin D toxicity can lead to nausea, vomiting, muscle weakness, and other symptoms.
Serious risks
- Toxicity can cause high blood and urine calcium. In extreme cases it may lead to kidney failure, soft tissue calcification, heart rhythm problems, and death.
- Toxicity is almost always caused by taking too much vitamin D through supplements.
Avoid or ask a doctor first if
- The source says people on regular medications should talk with their health care providers about vitamin D intake and status.
Medication interactions
- Vitamin D supplements may interact with orlistat, statins, steroids, and thiazide diuretics.
- Taking calcium supplements with vitamin D supplements may raise the risk of certain adverse effects.
Upper limit: 100 mcg a day for adults 19+. This label lists 12.5 mcg.
Source: NIH Office of Dietary Supplements, Vitamin D: Fact Sheet for Health Professionals
Thiamin
The body excretes excess thiamin in the urine. The FNB set no upper limit because adverse effects from high intakes (50 mg/day or more) haven't been reported, though it noted that excessive intakes could still have adverse effects.
Serious risks
- No adverse effects have been reported from high thiamin intakes, but the FNB noted that excessive intakes could still have adverse effects.
Avoid or ask a doctor first if
- People who take certain medications regularly should talk with their health care providers about their thiamin status.
Medication interactions
- Thiamin isn't known to interact with any medications, but certain medications can have an adverse effect on thiamin levels.
Source: NIH Office of Dietary Supplements, Thiamin: Fact Sheet for Health Professionals
Vitamin B12
The source says vitamin B12 has no tolerable upper intake level because of its low potential for toxicity, and it is generally considered safe even at large doses. Some medications can affect B12 levels, and supplements may interact with certain medications.
Serious risks
- The Food and Nutrition Board set no upper limit for B12 because its potential for toxicity is low.
Avoid or ask a doctor first if
- People who regularly take certain medications are told to talk with their health care providers about their B12 status.
Medication interactions
- B12 supplements may interact with some medications. Gastric acid inhibitors and metformin may affect B12 levels.
- Several types of medications might adversely affect B12 levels.
Source: NIH Office of Dietary Supplements, Vitamin B12: Fact Sheet for Health Professionals
Pantothenic Acid
The FNB could not set a Tolerable Upper Intake Level for pantothenic acid because there are no reports of toxicity in humans at high intakes. Some people taking large doses of supplements develop mild diarrhea and gastrointestinal distress. No clinically relevant medication interactions are known.
Possible side effects
- Some people taking large doses of pantothenic acid supplements develop mild diarrhea and gastrointestinal distress. The cause is not known.
Serious risks
- The FNB found no reports of pantothenic acid toxicity in humans at high intakes.
Medication interactions
- Pantothenic acid is not known to have clinically relevant interactions with medications.
Source: NIH Office of Dietary Supplements, Pantothenic Acid: Fact Sheet for Health Professionals
Carnitine
Carnitine has no established tolerable upper intake level. Doses of about 3 g/day of supplements can cause digestive upset and a fishy body odor, and some research links gut bacteria's breakdown of unabsorbed carnitine to possible CVD risk, though the implications are not well understood.
Possible side effects
- About 3 g/day of carnitine supplements can cause nausea, vomiting, abdominal cramps, diarrhea, and a fishy body odor.
Serious risks
- Some research indicates gut bacteria turn unabsorbed carnitine into TMAO and gamma-butyrobetaine, which might increase CVD risk; the implications are not well understood.
- Carnitine can cause seizures in people with seizure disorders.
Avoid or ask a doctor first if
- People with uremia can get muscle weakness, and people with seizure disorders can have seizures, from carnitine.
Medication interactions
- Several types of medications have the potential to interact with carnitine supplements.
- People taking medications regularly should discuss their carnitine intake with their healthcare providers.
