Anatomy of a buying decision
Three readings from one real product. This is what every page on SuppSignal is built around.
Clean Signal
Label transparency + testing + sourcing simplicity.
Dose Signal
Effective ingredient, in a studied range, in a real serving.
Value Signal
What it actually costs per dose, not per tub.
Deal watch · ticketed
Set a target price per effective serving. We'll alert you when a clean, well-tested product actually becomes a good deal. Sticker discounts don't qualify on their own.

The teardown · How to read SuppSignal
Every Product Passport is a small audit. Ten parts. Each one answers a real buying question. Here's the legend.

Live example · ranked #2 in creatine monohydrate
Total Signal
→ Top right of the passport
The overall score, 0 to 100. Weighted: Clean × 0.4, Dose × 0.3, Value × 0.3. Higher is better. 80+ is 'strong', 60-79 is 'mixed', below 55 is 'avoid'.
Clean Signal
→ First signal bar
Label transparency, third-party testing posture, sourcing clarity, and absence of red flags like proprietary blends or artificial colors. Weighted most heavily.
Dose Signal
→ Second signal bar
Whether the primary active is dosed in a commonly-studied effective range. A label saying '5g creatine monohydrate' beats a 'proprietary matrix' on this every time.
Value Signal
→ Third signal bar
Real cost per effective serving compared to the category median, plus coupon availability and retailer competition. Not just sticker price.
Effective $ per serving
→ First receipt row
What this product actually costs per dose, not per tub. Adjusted for whether the effective dose requires one serving or multiple. The single most useful commercial number on the page.
Testing status
→ Receipt row · Testing
Reads 'Verified third-party' only when a specific batch or registry entry has been independently confirmed. 'Brand-claimed only' means we trust the brand says so, but we can't link the proof.
COA status
→ Receipt row · COA
Whether a specific Certificate of Analysis matching this product family is publicly posted. Brands often publish general COA libraries; we don't promote to 'verified' until we link a real batch.
Claim confidence
→ Verdict stamp sub-label
The mono sub-label under the verdict stamp reads 'VERIFIED', 'CERT CLAIMED', 'TESTING CLAIMED', or 'MIXED SIGNALS' depending on actual evidence state. Never overclaims.
Watch-out
→ Red bullet above the verdict
The single most important caution we surfaced about this product. If a product has multiple watch-outs, we show the most material one here and link out to the full list on the product page.
Deal Watch trigger
→ Effective $/serving
The number you'd benchmark a Deal Watch threshold against. Set a target below this price and we'll alert you the moment it clears, gated by minimum Clean Signal.
The contract
Three rules · always
Scores cannot be bought
No brand has ever paid to change a Clean, Dose, or Value Signal.
Affiliate links do not affect ranking
Paid links use rel=sponsored. Ranking math is identical with or without.
Educational, not medical advice
Talk to a clinician before starting any supplement that affects medication.
