Nutrastop | Fat Burner | 90 Capsules

Hi-Tech Pharmaceuticals Fat Burner is a stimulant-forward thermogenic capsule built around a simple core idea: create a noticeable increase in energy and drive with enough adjunct ingredients to support appetite control, lipolysis, and a more aggressive cutting-phase feel than a basic caffeine-only fat burner. This is not a broad-spectrum health formula and it is not pretending to be one. It is a high-stim capsule designed for users who want a fast, compact thermogenic effect.

The fully disclosed portion of the label tells you where the formula starts. Caffeine anhydrous at 100mg provides rapid central nervous system stimulation through adenosine receptor antagonism, which increases alertness, perceived energy, and training readiness. On its own, 100mg is moderate. In this formula, though, it is paired with 2-aminoisoheptane HCl at 100mg, a stimulant commonly discussed as DMHA. DMHA is used in fat burners and pre-workouts for its sharper, more urgent stimulant profile, often described as more mood-elevating and forceful than caffeine alone. Human clinical data are limited compared with caffeine, so the evidence base is not as mature, but in practice this pairing is designed to feel materially stronger than 100mg caffeine would suggest by itself.

Garcinia cambogia extract at 200mg standardized to 60% hydroxycitric acid yields 120mg HCA. Garcinia is typically positioned for appetite support and carbohydrate handling through inhibition of ATP-citrate lyase, an enzyme involved in de novo lipogenesis. That mechanism is plausible, but this 120mg HCA yield sits below the more common research intakes often used in the several-hundred-milligram to gram range of HCA per day. In other words: it contributes to the formula concept, but it is not the star.

The undisclosed proprietary portion contains the ingredients that define the formula’s identity: Bauhinia purpurea, Bacopa monnieri, walnut bark extract, Cirsium oligophyllum, and rauwolscine extract. Bauhinia and Bacopa are often included in body composition formulas for metabolic and cognitive support. Bacopa has stronger evidence in nootropic contexts than in acute fat-burning contexts, where it is not typically a headline ingredient. Rauwolscine, however, matters. As an alpha-2 adrenergic antagonist, rauwolscine is commonly used in high-stim thermogenics to support lipolysis and create a more intense, edgy stimulant feel, especially when stacked with caffeine. Walnut bark extract in this category is often associated with stimulant alkaloid positioning, though exact activity depends on the extract profile. Cirsium oligophyllum has also appeared historically in body-composition products for lipolytic support.

The synergy is straightforward: caffeine increases alertness and thermogenic output, DMHA intensifies the stimulant experience, and rauwolscine adds a harder thermogenic edge that many experienced users specifically seek during a cut. The botanical support ingredients appear intended to broaden the formula beyond raw stimulation, but because their doses are hidden, their true contribution cannot be verified.

That leads directly to the transparency assessment. This is only partially transparent. Three actives are disclosed with exact amounts; the rest sit in a proprietary blend with hidden doses. In the fat-burner category that is common, but it still limits dose-by-dose analysis. Day 1, most users will notice energy, urgency, and reduced appetite before they notice anything else. Over 2-4 weeks, the practical value comes from better adherence to a calorie deficit, more productive cardio or training sessions, and less reliance on willpower alone. The formula’s strength is its aggressive stimulant architecture. Its limitation is that several key ingredients are impossible to fully evaluate because the label does not disclose their amounts.
