About CompareWhey
An independent protein comparison site focused on data transparency
CompareWhey is an independent protein comparison site created to solve a simple problem: it's incredibly difficult to compare protein powders based on what actually matters.
We aggregate publicly available data from official brand websites and product labels to help consumers make informed decisions. Our unique focus on leucine content—the most important amino acid for muscle protein synthesis—sets us apart from generic comparison sites.
Started in 2024, CompareWhey was born from frustration. Despite protein powder being a multi-billion dollar industry, there was no single resource that:
- •Compared products by leucine content (the key trigger for muscle growth)
- •Showed complete amino acid profiles for all products
- •Calculated cost per gram of leucine, not just protein
- •Was transparent about missing data instead of hiding it
So we built it ourselves. We're not backed by any supplement company. We're not pushing a particular brand. We're just trying to make protein comparison better.
Data Collection
We manually collect data from official brand websites, product labels, and certificates of analysis. This is time-consuming but ensures accuracy.
Transparency First
When data isn't available, we show it. About 30% of products lack complete amino acid profiles—we mark these clearly rather than estimating.
Regular Updates
We update our database as we discover new information. Prices are checked periodically (not real-time yet). Found an error? Please let us know.
Revenue Model
We earn commission from affiliate links when you purchase products. This doesn't affect our rankings—products are sorted by data, not commissions. Higher-commission products don't get preferential treatment.
Leucine Focus
We're the only site that prominently displays and compares leucine content—the most important amino acid for triggering muscle protein synthesis.
No Fake Data
We never make up numbers. Missing data is clearly marked. You'll see "N/A" often—that's us being honest.
Complete Profiles
When available, we show all 19 amino acids, not just the BCAAs that brands like to advertise.
Real Calculations
Our calculators use peer-reviewed research formulas, not marketing hype. Every calculation is referenced.
We believe in being upfront about what we can't do:
- •We're not real-time: Prices and availability are updated periodically, not instantly.
- •We can't test products: We rely on brand-provided data. We can't independently verify protein content.
- •We're incomplete: We're building our database. Many products still need data added.
- •We're a small project: Response times may be slow. Updates happen when we have time.
CompareWhey is an independent project focused on data transparency in the supplement industry. We're not a big company—just a small team passionate about making protein comparison better.
We don't have fancy offices or venture funding. What we do have is a commitment to providing accurate, unbiased information to help you make better supplement choices.
Want to contribute? We welcome corrections, additional data, and feedback. If you work for a brand and want to ensure your products have complete data, please get in touch.
Help Us Improve
Found incorrect data? Know of amino acid profiles we're missing? Have suggestions for new features? We genuinely want to hear from you.
