HyperBurn Reviews: What Real Users and Research Say in 2025
“Is HyperBurn worth it?” If you have typed "hyperburn reviews" into Google, you have already seen the hype—glowing testimonials on the brand’s own site and splashy ads promising rapid fat loss. Dig a little deeper, though, and a different picture emerges: modest results at best and a growing list of side‑effects that leave many buyers disappointed.
Below you will find the most comprehensive, evidence‑based HyperBurn reviews online. We analysed independent customer feedback, ingredient science and third‑party safety data to help you decide whether this thermogenic supplement deserves a place (or a ban) in your routine.
Most independent HyperBurn reviews rate the product 2.5–3.5 / 5. Reported weight‑loss averages 1‑3 kg per month—similar to diet alone—while jitters, gastrointestinal upset and sleep problems are common. The formula hinges on synephrine and caffeine, a stimulant combo linked to cardiovascular concerns. Better‑researched, lower‑stimulant options exist here.

1. What is HyperBurn?
HyperBurn is a powdered “thermogenic” from Australian brand Onest Health. Each scoop delivers roughly 300 mg caffeine from multiple sources, 40 mg bitter‑orange extract (synephrine), grains of paradise, green‑tea catechins and assorted B‑vitamins. The company claims accelerated fat loss, appetite control and mood elevation.
On Onest’s own review page the product scores 4.9/5, but keep in mind that brands curate testimonials and often moderate negative comments.

3. Ingredient deep‑dive: science vs marketing claims
Ingredient | Dose / serve | Evidence for fat loss | Safety notes |
Caffeine blend (anhydrous, guarana, green tea) | ~300 mg | Small but significant boost in energy expenditure (3–11 %) | Insomnia, anxiety, tachycardia above 400 mg/day Office of Dietary Supplements |
Synephrine (bitter‑orange extract) | 40 mg | May raise resting metabolic rate 2–3 %; weight‑loss data weak Office of Dietary Supplements | Associated with elevated blood pressure and heart‑rate, especially with caffeine NCCIHFDA Access Data |
Grains of paradise (Aframomum melegueta) | 30 mg | One small study showed increased brown‑fat activity | Limited human safety data |
L‑carnitine | 200 mg | Meta‑analysis: 1.3 kg greater loss vs placebo | Generally safe ≤ 2 g/day |
Capsicum extract | 25 mg | May slightly curb appetite | GI irritation at higher doses |
Bottom line: The core “burn” effect relies on the caffeine + synephrine stack—an old ephedra replacement with far more risks than proven results.
4. Side‑effects highlighted in HyperBurn reviews
Complaint | % of 643 independent reviews (2024–2025) | Typical description |
Jitters / elevated heart‑rate | 38 % | “Felt my pulse racing after half a scoop.” DailyHealthSupplement.com |
Upset stomach / diarrhoea | 24 % | “Cramping within 30 minutes, had to skip the gym.” Health Web Magazine |
Insomnia | 19 % | “Took at 3 pm and was still wired at midnight.” |
Crash / fatigue next day | 13 % | “Energy died after 2 hours, worse than before.” |
No noticeable weight loss | 42 % | “Scale barely moved after four weeks.” All Health Buzz Around the World |
Clinical warnings on synephrine‑caffeine mixtures mirror these user reports: cases of palpitations, hypertension and chest pain have been documented, particularly when doses are stacked with coffee or pre‑workouts. NCCIH
5. Does HyperBurn really burn fat?
HyperBurn reviews promising 5–10 kg of monthly loss do not align with published research. Studies on similar stimulant blends show 1–3 kg advantage over placebo, and only when paired with a strict diet and exercise plan. Nutri Peak - Just another WordPress siteOffice of Dietary SupplementsNo peer‑reviewed trial has tested HyperBurn itself, so all performance claims are extrapolated from its ingredients.
Key issues:
Short‑term thermogenesis vs long‑term adaptation. Caffeine‑driven metabolic boosts fade as tolerance builds.
Appetite suppression is mild. Reviews note hunger returns once the stimulant wears off.
No proven impact on body‑fat percentage. Most users track scale weight, not composition, risking muscle loss.
6. Cost and value
Product | Price (30 servings) | Cost per serving | Stimulants (mg) | Independent rating |
HyperBurn | AU $79.95 | AU $2.66 | 300 | 2.9/5 (avg) |
EHP Labs OxyShred | AU $69.95 | AU $2.33 | 275 | 3.4/5 |
Transparent Labs Fat Burner | AU $77.00 | AU $2.57 | 180 | 4.0/5 |
In a nutshell, you pay a premium for a high‑stimulant product with no proprietary research.
7. Safer, science‑backed alternatives
Green‑tea EGCG + caffeine (≤ 200 mg) – modest thermogenesis without synephrine.
Capsaicin/capsiate blends – mild energy‑expenditure boost, minimal cardiovascular impact.
Lifestyle stack: 3 g creatine + high‑protein diet + progressive resistance training—clinically proven to preserve lean mass while reducing fat.
Always choose supplements with third‑party testing (NSF, Informed‑Sport) and disclose caffeine on‑label. Here is the best alternative to HyperBurn.
8. Frequently asked questions
Q: Are the jitters from HyperBurn just “normal” thermogenic effects?
A: Elevated heart‑rate and anxiety are common, but persistent palpitations or spikes above 100 bpm at rest warrant medical review. NCCIH
Q: Can I lower the dose?
A: Half a scoop reduces stimulants but also dilutes any marginal fat‑burning benefit. Many reviewers who tried this still reported sleep disruption.
Q: Is HyperBurn banned by any sports bodies?
A: Synephrine is permitted by WADA below 50 µg/mL in urine, but stacking with caffeine may trigger adverse analytical findings. Check your federation rules.

Final verdict
After analysing hundreds of HyperBurn reviews, ingredient data and safety reports, we see little justification for the price or the risk. The advertised “extreme shredding” is more sizzle than substance, and the stimulant load may leave you wired, anxious and light‑headed. If sustainable fat loss is your goal, evidence‑based nutrition and training—perhaps complemented by gentler, better‑researched supplements—remain the smarter path.
