What a supplement price comparison covers
ScoopSignal compares retailer listings for identified supplement variants in India. The comparison starts with product identity, then records the retailer, price, check time and available stock information. This lets you distinguish a current matched offer from an older amount kept for reference.
Our catalog currently contains 101 product variants across 19 brands, with links to 23 retailers. Coverage varies by product. We do not cover every seller, pack, flavour or temporary promotion, so “best price” on the site means the lowest eligible current price among our matched offers for that product. It is not a lowest-price guarantee across the whole market.
Use the catalog to inspect a product’s retailer rows, or compare two products to examine their prices and label-based metrics together.
Product identity comes before the price
The brand, product line, pack size and flavour need to match the product being compared. A check for a different variant does not count as a current offer. Known variant mismatches and unavailable listings are also excluded from displayed price fallbacks.
This distinction matters when a retailer page switches its default flavour or pack, redirects to another listing, or shows several sizes under one address. A familiar product photograph alone is not sufficient evidence that the selected variant is the same.
When browsing whey protein, creatine, mass gainers, pre-workout or fermented yeast protein, open the specific product to review its matching retailer offers.
What a checked price means
A fresh price comes from a successful matched retailer check within the configured 70-minute freshness window. The amount must be a positive number, and a future-dated check is not accepted as fresh. Each displayed amount carries its retailer and source state so you can see what it represents.
The freshness window is an expiry rule, not a promise that every retailer will be checked successfully on that schedule. A listing may be blocked, inaccessible or awaiting another check. Once its successful check is too old, that price stops qualifying as a current deal.
A verified price describes a retailer listing at the recorded time. It does not verify supplement quality, laboratory results, product authenticity or suitability. Shipping, pincode eligibility, seller, selected variant and conditional discounts still need checking with the retailer.
Why an older price may remain visible
Fresh price: a successful exact-variant check within the freshness window. An explicitly out-of-stock offer can be shown with its stock state, but it cannot win the current-deal ranking.
Last verified: the most recent recorded successful amount, with its date, when a current price is unavailable. It records what was observed previously; it does not establish the retailer’s price today.
Catalog price: an amount from the imported catalog, shown with its source date when available. It is a fallback when neither a current nor a usable last-verified amount is available. It does not count as a current retailer check.
Fresh amounts take display priority over historical amounts. Within each source tier, offers not marked out of stock are shown before explicitly out-of-stock offers, then by ascending price. Last-verified amounts precede catalog fallbacks. Read the label before comparing a number across products: a price sort can include displayed fallbacks as well as fresh prices.
How current deals and stock are treated
Current-deal rankings use fresh matched prices that are not explicitly marked out of stock. The lowest eligible amount is the product’s best current price. Equal amounts can share that distinction. Partnership links do not change this price order.
Unknown stock is different from confirmed stock. A checked price can appear while local delivery availability remains unconfirmed; it does not establish that the retailer will deliver to your pincode. Stock alerts require an offer with confirmed in-stock status.
The Scoop Check price checker uses fresh eligible offers. If none are available, it cannot give a current price comparison from that product’s older amounts. You can still review the product page’s labelled price history or fallback information where available.
A worked example: cost per gram of protein
The following figures are hypothetical. They demonstrate the arithmetic and do not describe an actual offer, brand or product recommendation.
Imagine a 1,000 g pack costing — with a 32 g serving containing 24 g of declared protein. Calculate the pack’s serving count from its weight: 1,000 ÷ 32 = 31.25 servings. Its total declared protein is 31.25 × 24 = 750 g.
Cost per gram of declared protein = displayed price ÷ (net weight ÷ serving size × protein per serving). For this example: — ÷ 750 g = — per gram of protein. Cost per serving is — ÷ 31.25 = —; cost per gram of powder is — ÷ 1,000 = —
Use grams for the weight, serving and protein inputs. When net weight and serving size are available, we use their ratio rather than rounding the serving count printed on a pack. Where those inputs are unavailable, a declared serving count can be used if present.
These calculations use the displayed price and declared label figures, so their meaning depends on both sources. A result based on a dated last-verified price is dated too. Missing inputs leave a metric unavailable; protein cost is not useful for a product with no declared protein. The calculation is not a measure of absorption, quality, effectiveness or individual suitability.
Where the nutrition figures come from
Where available, we use recorded manufacturer sources for nutrition facts and serving information. The evidence includes a source name and link, the verification date and the basis of the figures. Check this information on the product page before using a nutrition comparison.
Products without that manufacturer evidence can retain imported catalog label data, identified separately. If nutrition information is missing, we do not fill the gap with figures from an unrelated product. Product formulas and flavours can differ; the relevant label is the one for the exact item being considered.
We do not independently laboratory-test supplements. A manufacturer-source nutrition label and a verified retailer price are separate pieces of evidence. Neither is an independent certification of the powder delivered to you.
Coverage limits and corrections
Retailer access, matching and data availability limit what we can show. A price may change after checking, a retailer may withdraw a listing, and delivery or coupon conditions may depend on your account or location. The retailer’s final checkout takes precedence.
Historical observations only show checks we actually recorded. Gaps between checks are not evidence that the price stayed constant, and an incomplete record cannot establish an all-time low. We do not manufacture price-history points to fill those gaps.
To report an issue, contact ScoopSignal with the product link, retailer URL, exact pack and flavour, and the amount or label detail you believe is incorrect. Include the time you saw it. If the issue concerns delivery, payment or a return, contact the retailer directly.
