Cellucor SuperHD Thermogenic Fat Burner
160mg caffeine, Capsimax cayenne extract, green tea extract, Slimpro protein hydrolysate, N-Acetyl-L-Tyrosine for focus. Moderate-stim formula with nootropic edge. ~$0.83/serving. 60 capsules.
- Combines fat burning with nootropic focus ingredients
- Moderate 160mg caffeine suits those who dislike high-stim
- Capsimax and green tea provide legitimate thermogenic support
- Well-known brand with wide retail availability
- Some ingredients in proprietary blend with undisclosed doses
- Higher cost per serving than Burn-XT (~$0.83 vs $0.67)
Quick Verdict
Cellucor SuperHD is a solid thermogenic fat burner that distinguishes itself by blending fat-burning ingredients with nootropic compounds for mental focus. The moderate 160mg caffeine dose is a good fit for men who find high-stim fat burners (like Burn-XT’s 270mg) too aggressive. The Capsimax, green tea, and Slimpro ingredients have research backing, and the addition of N-Acetyl-L-Tyrosine adds a genuine focus component you won’t find in most competitors. However, the partial use of proprietary blends and the higher price per serving keep it from taking the top spot. 4.1/5.

What Is Cellucor SuperHD?
Cellucor is one of the most recognized names in sports nutrition, best known for its C4 pre-workout line. SuperHD is their flagship fat burner, and it’s been through several reformulations since its original launch. The current version positions itself as a “high-definition” thermogenic — the idea being that it doesn’t just help you lose fat, it helps you stay mentally sharp and focused while doing it.
This is a meaningful differentiator. Most fat burners dump in as much caffeine as possible and call it a day. SuperHD takes a more nuanced approach, combining moderate-dose thermogenic ingredients with nootropic compounds designed to support mental clarity, mood, and focus during a calorie deficit. Anyone who’s dieted hard knows that cognitive function and mood tend to suffer when calories are low — SuperHD attempts to address that directly.
Cellucor is owned by Nutrabolt, a major player in the supplement industry with distribution in over 150 countries. SuperHD is manufactured in cGMP-certified facilities and is widely available both online and in brick-and-mortar retailers like GNC, Walmart, and The Vitamin Shoppe. The brand’s retail presence is one of the broadest in the fat burner category.
However, transparency is where SuperHD falls short of competitors like Jacked Factory. While some ingredients list their exact doses, others are grouped into proprietary blends with undisclosed individual amounts. This is a common practice in the industry, but it’s a step backward from the full transparency that products like Burn-XT offer. We’ll break down exactly what’s disclosed and what isn’t in the ingredient section below.

Ingredient Breakdown
Caffeine Anhydrous (160mg): This is one of the few individually disclosed doses in SuperHD, and it’s a deliberate choice. At 160mg, it’s roughly equivalent to one and a half cups of regular coffee. This sits firmly in the moderate-stimulant zone — enough to increase energy expenditure, boost alertness, and enhance workout performance, but significantly less than the 250–300mg found in high-stim competitors. Research shows caffeine’s thermogenic effect is dose-dependent, so 160mg will produce less metabolic increase than 270mg. The tradeoff is better tolerance, fewer side effects, and more flexibility to consume caffeine from other sources throughout the day.
Capsimax (Cayenne Pepper Extract): The same patented beadlet-form capsaicinoid extract found in Burn-XT. Capsimax delivers its active compounds in the intestine rather than the stomach, avoiding gastric irritation. Research supports capsaicinoids for increasing energy expenditure (roughly 50 additional calories per day) and enhancing fat oxidation. The issue with SuperHD is that Capsimax’s exact dose is not individually disclosed — it’s part of a proprietary blend. Without knowing the precise amount, we can’t confirm whether it’s at the clinically studied dose of 100mg or a lower, potentially less effective amount.
Green Tea Extract (EGCG): Another ingredient shared with most quality thermogenic formulas. EGCG increases fat oxidation and works synergistically with caffeine to enhance thermogenesis. Meta-analyses support the caffeine-plus-catechin combination for modest increases in energy expenditure. Like Capsimax, the exact dose of green tea extract in SuperHD is not individually listed, making it difficult to compare directly with Burn-XT’s transparent 450mg dose.
Slimpro (Protein Hydrolysate): This is a more unique inclusion. Slimpro is a proprietary protein hydrolysate derived from potato protein that has been studied for its effects on appetite regulation. Research published in the Journal of the American College of Nutrition found that Slimpro supplementation led to reduced calorie intake by promoting satiety hormone release (specifically CCK, cholecystokinin). The idea is that Slimpro helps you feel fuller on fewer calories, making it easier to maintain a deficit. It’s a smart inclusion for a fat burner, addressing the behavioral side of dieting rather than just the metabolic side.
N-Acetyl-L-Tyrosine (NALT): This is the nootropic ingredient that gives SuperHD its “focus boost” identity. Tyrosine is a precursor to dopamine, norepinephrine, and epinephrine — neurotransmitters involved in focus, motivation, and mood. The N-acetyl form is more water-soluble, though there’s debate about whether NALT is actually better absorbed than standard L-tyrosine. Research shows tyrosine supplementation can improve cognitive performance under stress, including the stress of calorie restriction. During a hard cut, when mental sharpness tends to decline, this ingredient provides a genuine benefit.
Pros & Cons
What We Like
- Focus-enhanced formula: The combination of moderate caffeine, N-Acetyl-L-Tyrosine, and the overall formula design creates a noticeable boost in mental clarity and focus. During a calorie deficit — when brain fog and irritability are common — this cognitive support is genuinely valuable. Most fat burners ignore this entirely.
- Moderate caffeine dose: At 160mg, SuperHD provides stimulation without overwhelming the system. You can still have a cup of coffee in the morning and take SuperHD before your afternoon workout without exceeding 400mg total daily caffeine. This flexibility is a real advantage for men who don’t want to structure their entire caffeine intake around a fat burner.
- Slimpro for appetite control: The inclusion of a clinically studied appetite-regulating ingredient addresses one of the biggest challenges of fat loss — hunger. This is a thoughtful addition that demonstrates Cellucor actually considered the real-world dieting experience, not just thermogenic metrics on paper.
- Wide retail availability: SuperHD is available at GNC, Walmart, The Vitamin Shoppe, Amazon, and most supplement retailers. If you prefer buying in person, seeing the label before purchasing, or returning to a physical store, SuperHD is far more accessible than online-only brands.
What Could Be Better
- Proprietary blends: This is the biggest issue. While caffeine is individually disclosed at 160mg, several key ingredients (Capsimax, green tea extract, NALT) are grouped into blends with only the total blend weight listed. You don’t know if you’re getting 100mg of Capsimax or 10mg. In 2026, when competitors like Jacked Factory fully disclose every dose, this lack of transparency is a competitive disadvantage and a legitimate concern.
- Higher price per serving: At ~$0.83 per serving, SuperHD costs roughly 24% more than Burn-XT ($0.67) while arguably delivering less thermogenic potency due to its lower caffeine and undisclosed ingredient doses. The focus ingredients and brand premium account for some of this, but it’s still a harder value proposition.
How It Compares
The most natural comparison is with Jacked Factory Burn-XT, the #1 pick in our fat burner rankings. Burn-XT delivers 270mg caffeine, fully disclosed doses of Capsimax (50mg), green tea extract (450mg), ALCAR (700mg), and BioPerine (5mg) for ~$0.67 per serving. SuperHD counters with its focus ingredients (NALT, Slimpro) and a more moderate caffeine dose, but at a higher price with less transparency. For pure thermogenic fat-burning potency and value, Burn-XT wins. For men who want a milder stimulant experience with nootropic focus support, SuperHD has a legitimate niche.
Against Jacked Factory Lean-XT, the comparison is about stimulant tolerance. Lean-XT is completely stimulant-free, making it ideal for caffeine-sensitive users or evening dosing. SuperHD’s 160mg caffeine is moderate, but it’s still a stimulant product. If you’re looking for a middle ground between Burn-XT’s high-stim and Lean-XT’s no-stim approaches, SuperHD occupies that space.
Compared to other branded fat burners like Hydroxycut Hardcore Elite, SuperHD offers a more thoughtful formula with the addition of focus-oriented ingredients. Hydroxycut leans heavier on caffeine (270mg) with a simpler thermogenic formula. SuperHD provides a more well-rounded experience at the cost of some raw thermogenic intensity.

Who Should Buy Cellucor SuperHD
- Men who want fat-burning support combined with mental focus and clarity during a calorie deficit
- Anyone who finds 250–300mg caffeine fat burners too stimulating but still wants some caffeine-driven energy
- Lifters who value the cognitive side of supplementation and experience brain fog or mood dips during cuts
- Those who prefer buying from major retail stores (GNC, Walmart, Vitamin Shoppe) rather than online-only brands
- Men who are moderate caffeine consumers and want a fat burner that integrates easily into their existing caffeine intake
Who Should Skip It
- Men who demand full label transparency and exact doses for every ingredient — the proprietary blends are a dealbreaker for informed consumers who want to know precisely what they’re taking
- Budget-conscious buyers who can get better value and transparency from Burn-XT at $0.67 per serving
- Anyone who is completely stimulant-free — even 160mg of caffeine is still a stimulant (see Lean-XT instead)
- Men who want maximum thermogenic intensity — the lower caffeine and undisclosed thermogenic doses mean SuperHD likely generates less metabolic heat than Burn-XT

Check Current Price on AmazonFrequently Asked Questions
Is 160mg of caffeine enough for a fat burner to work?
Yes, 160mg is within the range shown to increase metabolic rate in research studies. The thermogenic effect is dose-dependent, so you’ll get less metabolic boost than from a 270mg product like Burn-XT. However, 160mg still provides meaningful energy, alertness, and calorie-burning enhancement. For many men, the slightly lower effect is worth the better tolerance and fewer side effects.
What does Slimpro actually do?
Slimpro is a proprietary protein hydrolysate (derived from potato protein) that has been shown in clinical studies to stimulate the release of CCK (cholecystokinin), a satiety hormone that signals fullness to the brain. The practical effect is reduced appetite and calorie intake at subsequent meals. Think of it as an appetite management tool rather than a thermogenic — it helps you eat less by making you feel fuller.
Why doesn’t Cellucor disclose all ingredient doses?
Cellucor uses proprietary blends for some ingredient groupings, disclosing the total blend weight but not individual ingredient doses. The company’s stated reason is formula protection — preventing competitors from copying exact ratios. However, many consumers and reviewers (ourselves included) view this as a transparency issue. Competitors like Jacked Factory fully disclose all doses, and their formulas haven’t suffered from being “copied.” We’d like to see Cellucor move toward full transparency in future reformulations.
Can I take SuperHD with C4 pre-workout?
Be cautious. Cellucor C4 Original contains 150mg caffeine per serving. Combined with SuperHD’s 160mg, you’d be at 310mg — within the FDA’s 400mg daily guideline but potentially too much for moderate caffeine users. If you stack them, avoid additional caffeine from coffee or energy drinks. Alternatively, use a stimulant-free pre-workout on days you take SuperHD.
How does SuperHD compare to SuperHD Fire and other SuperHD variants?
Cellucor has released several SuperHD variants over the years, including SuperHD Fire (a liquid capsule version) and SuperHD Xtreme. The standard SuperHD capsule reviewed here is the core product and typically the best value. The variants add or modify ingredients but often at a higher price point without dramatically different results. We recommend starting with standard SuperHD before exploring variants.
When should I take SuperHD?
Take 2 capsules with water, ideally 30–60 minutes before a workout or in the morning with breakfast. The 160mg caffeine is moderate enough that early-afternoon dosing (before 2 PM) shouldn’t disrupt sleep for most people, but individual caffeine sensitivity varies. Start with 1 capsule to assess tolerance before moving to the full 2-capsule dose.
Is SuperHD safe for long-term use?
The individual ingredients in SuperHD (caffeine, green tea, cayenne, tyrosine) have all been studied with acceptable safety profiles for ongoing use. However, most fat burners — including SuperHD — are designed for use during cutting phases rather than year-round supplementation. A common approach is 8–12 weeks on, followed by 2–4 weeks off to prevent caffeine tolerance buildup and give your system a reset. This cycling approach maintains effectiveness and reduces the risk of caffeine dependency.
Final Rating: 4.1/5
Cellucor SuperHD is a well-conceived fat burner that offers something genuinely different from the high-stim crowd. The focus-enhancing nootropic ingredients address a real problem — cognitive decline during calorie restriction — and the moderate caffeine dose makes it accessible to men who don’t want to feel like they’ve mainlined espresso. The Slimpro appetite-control ingredient is a thoughtful addition that most competitors overlook.
Where SuperHD falls short is transparency and value. The proprietary blends are an outdated practice that makes it impossible to verify whether key thermogenic ingredients are clinically dosed. And at $0.83 per serving, it’s notably more expensive than Burn-XT, which offers full transparency and stronger thermogenic doses for less money. SuperHD isn’t a bad product — it’s a good product that could be great if Cellucor embraced full label disclosure. For men who specifically want moderate caffeine with focus support, it’s a solid choice. For everyone else, Burn-XT remains our top recommendation.
