SuperHD is the fat burner you've actually seen before — Cellucor is one of the most established names in mainstream sports nutrition, and this is its long-running thermogenic flagship. The evidence core deserves genuine credit: a sensibly moderate 160 mg of caffeine disclosed right on the front, GreenSelect green tea phytosome (a branded, absorption-focused catechin extract) and Capsimax cayenne — which is to say, the two ingredients that actually carry this category's evidence, plus its most defensible minor player, at a fair price in a convenient single-capsule serving. Why it sits at #6 rather than in the top half comes down to the two habits our methodology penalizes. First, transparency: several ingredients live inside a named 'Sensory Blend' with one combined weight, so part of the label can't be audited — better than a fully-hidden formula, worse than the fully-disclosed picks above it. Second, stimulant stacking: alongside the caffeine, SuperHD includes yohimbe and rauwolfia, which push the real stimulant load well past what the 160 mg suggests and buy side-effect risk (anxiety, racing heart, blood pressure) rather than proven fat loss. A reasonable buy for the stimulant-tolerant Cellucor loyalist; a step down from the transparent, cleaner-stim tools above it. Here's the full breakdown.

Read the complete Weight Loss guide →A split verdict: the headline actives — 160 mg caffeine, the GreenSelect and Capsimax components — are disclosed, which beats the category's worst habits. But several supporting ingredients share one combined weight inside the named 'Sensory Blend,' so part of the label can't be audited or compared to studied doses. Partial opacity on our heaviest-weighted criterion is what most separates SuperHD from the top five.
The core is genuinely good: moderate caffeine (the category's best-evidenced ingredient, Tabrizi 2019), GreenSelect green tea phytosome (a branded catechin extract — the second-best, Hursel 2009), and Capsimax (the most defensible minor thermogenic). The deduction is for the yohimbe and rauwolfia: stimulants that add side-effect load without adding evidenced fat loss — exactly the trade our methodology marks down.
Cellucor is a large, established mainstream brand with real manufacturing QA and enormous market exposure — problems would surface fast at its volume, which is meaningful indirect assurance. Branded actives (GreenSelect, Capsimax) add supplier-level standardization. The gaps: no named independent certification for this SKU, and the blend structure limits what even good QA lets a buyer verify.
Fair mid-range value: 60 capsules at single-capsule servings works out to a reasonable per-serving cost, and wide retail availability means it's often discounted. It loses ground to Burn-XT's category-best pricing and to the fact that part of what you're paying for (the blend contents, the yohimbe) is either unauditable or unwanted.
“160 mg caffeine per serving with green tea extract and Capsimax.”
The headline doses are disclosed on the listing and label: 160 mg caffeine per serving alongside GreenSelect green tea phytosome and Capsimax cayenne. These are the formula's evidence-bearing components and they're stated plainly — the best part of the label.
“Thermogenic fat burner / weight-loss support.”
Supported at ingredient level by the category's standard modest evidence — caffeine (Tabrizi 2019, PMID 30335479) and green tea catechins (Hursel 2009, PMID 19597519) show small, real effects on weight and fat. As for every product in this lineup: a marginal aid on top of a calorie deficit, not a driver.
“Enhanced energy and sensory experience.”
The caffeine plus yohimbe/rauwolfia stack will absolutely be felt — that part is true. The honest translation is that the 'sensory' intensity comes from extra stimulant load, which for many users means jitters, anxiety and a racing heart rather than a benefit. Real effect, misleading framing of what causes it.
“Supports appetite control.”
Caffeine and Capsimax both have modest appetite-blunting data, so the claim has a plausible basis. But several appetite-adjacent ingredients sit inside the Sensory Blend at undisclosed doses, making the claim unauditable at the product level — the recurring cost of partial label opacity.
Strip SuperHD to its disclosed actives and you have close to a model thermogenic: 160 mg of caffeine is the sensible-moderate zone our dosage guide recommends, GreenSelect is a branded green-tea phytosome designed for catechin absorption, and Capsimax is the best-supported minor thermogenic. That trio is more evidence-literate than most of the category manages. SuperHD's problem was never its core — it's everything wrapped around the core: the blend that hides supporting doses and the stimulant hitchhikers that raise the cost of taking it. A cleaned-up SuperHD would contend for the top three; this one earns exactly the 7.6 it gets.
Yohimbine is the category's most predictable source of bad experiences — anxiety, racing heart, elevated blood pressure — and rauwolfia (a related alkaloid source) compounds the same axis. Neither carries fat-loss evidence remotely comparable to caffeine's, so their inclusion buys intensity, not results: the formula feels stronger without being better. Our methodology explicitly demotes this trade, and it's half the reason SuperHD sits at #6. Practical rule: if you've ever had a bad reaction to a pre-workout or an energy drink, this is not your product — and even tolerant users should dose early and never stack it with other stimulants.
SuperHD's label sits exactly between the category's poles. Unlike the worst offenders, it discloses its headline doses — you know the caffeine number and the branded actives. Unlike the best, it parks several supporting ingredients in a named blend with one combined weight, so you can't verify their doses or compare them to any study. In a ranking whose heaviest weight (35%) exists precisely because dose-hiding is the category's core sin, a half-transparent label gets a half-credit score: 7.2, the gap that keeps an otherwise-competitive product out of the top five. The fix would cost Cellucor one label redesign.
There's a real buyer for SuperHD: someone who trusts Cellucor from years of mainstream availability, wants a single-capsule serving at a fair, frequently-discounted price, tolerates stimulants without drama, and doesn't weight full label auditability the way our methodology does. For that buyer it will do its modest job — caffeine-driven energy and mild appetite support on top of whatever calorie deficit is actually producing their results. Run it early in the day, count the 160 mg (plus the yohimbe intensity) against your total stimulant budget, and hold the same three-to-four-week honest review as any burner: energy and adherence up, sleep intact, or drop it.
SuperHD earns its place in the lineup with a genuinely evidence-literate core — moderate disclosed caffeine, a branded green-tea phytosome, Capsimax — from a brand whose scale is its own quality signal, at a price and availability the boutique picks can't match. If the fat-burner aisle at a mainstream retailer is where you're shopping, this is the most defensible thing in it. But our ranking exists to compare against the best, and against the best SuperHD gives back points in exactly the two places that matter most: the 'Sensory Blend' makes part of the label unauditable in a category whose defining sin is dose-hiding, and the yohimbe/rauwolfia additions turn a sensible 160 mg formula into a hotter stimulant stack that trades side-effect risk for zero proven gain. The picks above it — Phoenix's total transparency, Burn-XT's clean value, QuadraLean's disclosed focus stack — all deliver the same evidence core without one or both of those costs. Consider SuperHD if brand and convenience decide it for you; buy upward if the label or your stimulant tolerance decides it.

SuperHD's disclosed 160 mg sits in the sensible-moderate band — the evidence supports the caffeine, not the yohimbe/rauwolfia stacked on top of it.
Meta-analysis of 11 trials: green tea catechins (usually with caffeine) produced roughly ~1.3 kg of extra weight loss/maintenance. The basis for SuperHD's GreenSelect phytosome inclusion — the formula's second evidence-bearing component, modest like everything in this category.
