Transparency is core to WheySearch. This page explains how we collect data, calculate rankings, and present product comparisons. No black boxes, no hidden scores.
1. Data Collection
We source product information from Amazon.com listings, official brand websites, and nutrition labels. Key data points include:
- Product name, brand, and variant (flavour, size)
- Price and number of servings per container
- Protein, carbs, fat, sugar, fibre, and calories per serving
- Key active ingredients (creatine content, caffeine, BCAAs, etc.)
- Diet type (vegetarian, vegan, non-veg) where applicable
We update our database regularly. Prices on WheySearch are indicative -- always confirm the current price on Amazon.com before purchasing.
2. Price-Per-Serving Calculation
Price-per-serving is the single most important metric for comparing supplement value. We calculate it as:
This normalises products of different sizes into a single comparable number. A 1 kg tub and a 2 kg tub can be compared directly when you know what each serving costs.
3. How We Rank Products
Default sort order on category and comparison pages considers:
- Price per serving -- lower is generally ranked higher within the same category.
- Nutritional profile -- protein content per serving, sugar content, and active ingredient dosage are factored in.
- Brand reputation -- established brands with third-party testing tend to rank higher when other factors are equal.
You can always re-sort by price, protein, or other metrics using the filters on each page. We provide the data -- you decide what matters most.
4. What We Don't Do
- We do not accept payment from brands for higher placement or better scores.
- We do not let affiliate commissions influence rankings. Every product links to Amazon.comequally.
- We do not provide medical or nutritional advice. WheySearch is a comparison tool, not a substitute for professional guidance.
5. Blog & Editorial Content
Our blog posts are written with the same data-first approach. Product picks in articles are based on nutritional value and price -- not sponsorships. When we link to a product, it is always an affiliate link, which we disclose on our Affiliate Disclosure page.
6. Corrections & Feedback
