Key Ingredient Breakdown

What Each Ingredient Supports

Thermo-Z Ephedra
25mg · Energy & Thermogenic Support
Thermo-Z brand ephedra extract is the headline ingredient in Stimerex-ES.† It supports the product’s high-stimulant energy and thermogenic profile, making it best suited for experienced stimulant users rather than beginners.†
Senegalia Berlandieri
Thermo-Rx · Stimulant Alkaloid Support
The official Hi-Tech page describes Stimerex-ES as built around a Thermo-Rx stimulant-based configuration of phenylethylamine alkaloids from Senegalia Berlandieri.† This supports the product’s energy, alertness, and weight-management positioning.†
Caffeine
Energy & Alertness Support
Caffeine supports alertness, energy, and intensity.† Because Stimerex-ES is already stimulant-heavy, users should not combine it with coffee, energy drinks, stimulant pre-workouts, or other caffeine-containing products.
Green Tea
Metabolic & Antioxidant Support
Green tea is commonly used in thermogenic and weight-management formulas to support metabolic activity and antioxidant wellness.† In Stimerex-ES, it helps round out the diet and energy support profile.†
Citrus Aurantium
Thermogenic Support
Citrus aurantium is included as part of the stimulant and thermogenic support system.† Users should avoid stacking it with other products containing synephrine, phenylephrine, ephedrine, pseudoephedrine, or similar stimulant ingredients.
Yohimbe
Advanced Stimulant Support
Yohimbe is commonly used in stimulant-based weight-management formulas.† Sensitive users should approach yohimbe carefully because it may feel strong and may not be appropriate for users with blood pressure, anxiety, or stimulant sensitivity concerns.
Theobromine
Smooth Energy Support
Theobromine is included to support smoother energy, alertness, and stimulant feel.† It helps round out the energy profile beyond caffeine and ephedra alone.†
5-HTP
Mood & Appetite Support
5-HTP is included as part of the formula’s mood and appetite-support profile.† Users taking antidepressants or other serotonergic medications should not use this product unless cleared by a physician.
5-Methoxytryptamine
Mood-Support Compound
5-methoxytryptamine is listed on the official source page as one of the active ingredients associated with the formula.† It contributes to the broader energy and mood-support positioning of Stimerex-ES.†
Phenylethylamine
Focus & Drive Support
Phenylethylamine is included to support alertness, focus, and training drive.† It is one of the reasons Stimerex-ES should be treated as an advanced stimulant formula, not a casual daily energy capsule.
