Two Scores,Two Questions
Every recommendation on Super Achiever Club rests on two branded scores. One tells you whether a substance actually works for your goal. The other tells you which specific product to buy. They answer different questions on purpose — and this page defines both, in full.
One measures the substance. The other measures the product.
It’s the difference between “does creatine build muscle?” and “which tub of creatine should I actually buy?” Those are two separate decisions, so we give them two separate scores on two deliberately different scales — you can never confuse a 76 for a 9.2. Tap either card to jump to its full breakdown.
SAC Efficacy Score™
0–100Does this substance actually work for this goal?
Scores a substance against a goal— how much it actually moves the needle. Shown on goal pages and substance hubs.
- Effect size
- Evidence strength
- Reliability across people
SAC Product Score™
0–10Is this specific product the right one to buy?
Scores a specific productwithin its category — the exact formula, brand and dose. Shown on reviews, listicle picks and the Market Report.
- Form & standardisation
- Dose vs clinical range
- Third-party testing & transparency
- Value per effective dose
- Real-world fit & adherence
SAC Efficacy Score™
Does this substance actually work for this goal?
The SAC Efficacy Score™ answers one question and only one: does this substance actually work for this specific goal?Not whether a product is well made — that’s the other score — but whether the ingredient itselfearns its place in your routine for the result you’re chasing. Creatine for strength. Tongkat ali for testosterone. The same substance can score high for one goal and low for another, which is exactly why the score is always tied to a goal, never floated on its own.
We score it on a 0–100 indexon purpose. A 0–100 number reads instantly as a “how strong is the case” index — like a confidence percentage — and it keeps it from ever being mistaken for the product’s 0–10 rating sitting next to it. Two scales, zero confusion: if you see a number in the 70s or 80s, you know you’re looking at a substance, not a tub on a shelf.
- 01Effect sizeHow big the result is in the trials — a 30% improvement counts for far more than a statistically-significant 2% nudge.
- 02Evidence strengthHow trustworthy the proof is — large human RCTs and meta-analyses outrank small studies, animal data and anecdotes.
- 03Reliability across peopleHow consistently it works from person to person — a substance that helps almost everyone beats one that works for a lucky few.
How the composite is formed
We blend those three components — Effect size, Evidence strength, Reliability across people— into a single weighted editorial figure on the 0–100 scale. A large, reliable effect backed by strong human trials pushes the number up; a small or shaky effect, or evidence that’s mostly animal or anecdotal, pulls it down.
Then the community half kicks in. Once a substance passes 20 verified community ratings, the final score becomes 50% editorial and 50% community— the editorial figure and the verified-member figure carry equal weight. Below 20 ratings we show the editorial half only and mark it clearly; we won’t pretend a handful of reviews is a community consensus.
SAC Product Score™
Is this specific product the right one to buy?
The SAC Product Score™ answers a completely different question: once you’ve decided a substance is worth taking, which specific product should you buy? A substance can be brilliant and still sold in a badly dosed, untested, overpriced tub. This score judges the execution— the exact formula, brand, dose and price in front of you — not whether the ingredient works in general.
We score it on a 0–10 ratingon purpose. A 0–10 figure reads the way people already read product ratings — a 9.2 feels like a near-perfect buy, a 6.4 like a compromise — and the smaller scale instantly sets it apart from the substance’s 0–100 index. You will never mix up “the substance scores 82” with “this product scores 8.2”, because the scales themselves tell you which question you’re looking at.
- 01Form & standardisationThe right, best-absorbed form of the active — a standardised extract or a bioavailable salt, not a cheap filler form riding on a famous name. The heaviest-weighted criterion (~30%).
- 02Dose vs clinical rangeWhether one real serving actually reaches the amount used in the studies — not an under-dosed sprinkle that could never reproduce the result (~25%).
- 03Third-party testing & transparencyIndependent lab proof of purity and identity, plus a fully open label — every active and its exact amount, no proprietary blend hiding how little you get (~20%).
- 04Value per effective doseWhat it truly costs per serving that does something — the price of an effective dose, not the sticker price on the tub (~15%).
- 05Real-world fit & adherenceWhether you will actually keep taking it — format, taste, pill burden and tolerance. A pleasant daily gummy you never skip beats a chalky horse-pill you abandon (~10%). On individual reviews this criterion appears under a category-specific name such as “Format & adherence” or “Real-world response” (and for fish/krill oils it becomes sourcing & provenance).
How the composite is formed
We blend those five criteria — Form & standardisation, Dose vs clinical range, Third-party testing & transparency, Value per effective dose, Real-world fit & adherence— into a single weighted figure on the 0–10 scale, with form and dose carrying the most weight. Every review shows its exact weighted breakdown, so you can see precisely how a product landed at its number and which criterion cost it points.
The exact labels and weights are tailored to each category, because the same question takes a different shape per product type. A krill oil is judged on its EPA+DHA content and IFOS oxidation testing; an ashwagandha gummy on its extract standardisation and its format & adherence(taste, sugar and how reliably you take it). Both are still measured against the same five questions above — only the wording on the review changes to fit the product.
The community half works identically to the efficacy score. Once a product passes 20 verified community ratings, the final score becomes 50% editorial and 50% community— equal weight, no editorial veto on the community number. Below 20 ratings we show the editorial half only and invite members to be the first to rate.
A 50/50 split — by design.
Both scores run on the same engine: half our editorial assessment, half verified community ratings. We control one half. The community controls the other. Neither half can stack the deck.
Editorial Science
What the evidence actually says, weighted by how strong that evidence is.
- 25%Quality of human-trial evidence. Randomised controlled trials and meta-analyses score highest. Animal data and self-reports score lowest.
- 10%Effect size vs placebo. A statistically significant 2% bump is not the same as a 30% bump. Magnitude matters.
- 10%Real-world experience reports. Patterns across the SAC community — what actually moved the needle for members running the protocol.
- 5%Safety, tolerability, cost. A supplement that works but costs $200/month or causes side effects in a third of users is penalised here.
Community Rating
What actually worked for verified members who ran the protocol. Equal weight to the editorial half — not a garnish.
- 30%“Did this actually work?” Verified-member ratings after they ran the mission for the recommended duration.
- 15%Star ratings on the listicle.Star rating left on the specific product pick — formula, brand, dose.
- 5%Mission-completion + re-runs.If members finish the protocol and run it again, that’s a strong signal. If they drop it halfway, that’s a strong signal too.
Community ratings unlock at 20+ verified reviews per supplement. Until that threshold, the composite shows editorial only and is marked accordingly — we won’t pretend three reviews are a community consensus.
The specifics that decide a ranking.
When we open a study, an ingredient panel, or a brand’s certificate of analysis, these are the six things we check first.
Human RCTs
Randomised, controlled, placebo-blinded trials in humans — not rats, not in-vitro, not survey data dressed up as a study.
Standardisation
The active compound listed on the label, at a specified percentage, matched to the extract used in the studies we cite.
Clinical Dosing
The dose on the bottle matches the dose in the trials. Under-dosing is the easiest way for a brand to claim a study without earning it.
Third-Party Testing
Certificate of analysis from an independent lab. Heavy metals, microbiological contamination, and identity verification all visible to the customer.
Real-World Reports
Patterns across the SAC community and trusted external forums — what consistently shows up, what consistently doesn’t.
Safety Profile
Tolerability across trials, known interactions, and the shape of the side-effect curve at the recommended dose.
The anti-patterns we’ll never play along with.
- Paid placements.A brand cannot buy a ranking. Affiliate links exist on this site — they attach after the ranking is decided, never before, and never on the order of picks.
- Brand-funded studies as primary evidence. We will cite them — transparency demands it — but they cannot be the load-bearing study behind a top ranking. Independent RCTs do that work.
- “Natural” without proof. Natural is not an argument. Mercury is natural. A supplement gets credit for trial data, not for the herb it came from.
- Ambassador deals before review.Editorial review happens first, in isolation. Commercial relationships — if any — come strictly after, and never change a ranking that’s already published.
Why we wait for 20 verified ratings.
The community half of either score isn’t a five-star widget at the bottom of a product page. It’s a structured rating gated behind real use.
A rating only counts if the member ran the corresponding mission — the protocol that includes the dose, duration, and stack — and submitted their review after the post-mission window. Drive-by stars and first-day reviews don’t hit the score.
We unlock the community half at 20 verified ratings. Under that threshold, the composite shows editorial only and the card explicitly marks the community half as “Be the first to rate.” Three reviews aren’t a consensus — twenty are the floor where the average starts behaving like one.
Once unlocked, the score is live. As new ratings come in, the composite shifts and the ranking re-sorts on the next render. There’s no editorial veto on the community number — the math runs the same way for every pick.
Rankings update automatically. So do corrections.
Rankings re-sort on every page render. A new study lands, the editorial score moves. Twenty more verified ratings come in, the community half kicks in or shifts. The page you read today may not be the page you read in six months — and that’s the point.
If we make a factual error — a misread study, a wrong dose, an outdated safety note — we fix it, re-score, and disclose the change in the article’s edit log. Quiet edits are how trust gets eroded. We don’t do quiet edits.
