Compare 3,000+ protein powders by actual protein per dollar. Filter by protein type (whey/plant), diet (vegan/keto), flavors, price range, ratings. Real Amazon prices updated daily. See all sizes/flavors grouped together. Find your best deal instantly.

Hey hunters! 👋

I used to create a spreadsheet manually to compare protein powders every time I was going to buy. When friends started asking to use my spreadsheet, I realized this needed to be a more scalable system that could be shared and always stay up to date.

So I built PricePerProtein - it automatically pulls prices from Amazon daily and calculates the actual protein per dollar for 3000+ products. No more manual spreadsheets, no more outdated data.

I also shipped an MCP server for this project. It exposes the data as a MCP tool, so your LLM client can query the data directly (and do filtering / sorting). Totally unnecessary for most users, but it’s fun to use. mcp.priceperprotein.com

Would love your feedback! What would make your protein shopping easier?

Price per gram of protein is the metric that matters. Smart to group all sizes/flavors together. Do you calculate based on serving size protein or total container protein?

Also launching today (ZenTrack) - upvoted!

@grainoI calculate using total protein per container, not per serving, because serving sizes vary by brand. Thanks. Checked out your product, good luck today.

@batuhan_usluel Thanks for checking out ZenTrack, Batuhan!

Total container makes way more sense - eliminates the serving size manipulation some brands do. This is going to save so many people from overpaying!
