Key Insights
Key Takeaway
For a lean-muscle-focused lifter, AI routes to a stable Optimum Nutrition, Transparent Labs, and Dymatize core, but the aggregate #1 split three ways this run (Transparent Labs for ChatGPT, Momentous for Claude, Optimum Nutrition for Gemini and Perplexity) rather than consolidating on one brand. A brand outside that core plus Momentous and Nutricost is effectively invisible at purchase intent unless the buyer names it.
Top Brands Summary
Optimum Nutrition is the most-mentioned brand overall (in all 12 responses) and the aggregate #1 for Gemini and Perplexity, but the top pick split this run: ChatGPT aggregate-leads Transparent Labs (its #1 in both P1 and P3) and Claude aggregate-leads Momentous (its #1 in P1 and P3). Transparent Labs and Dymatize are the locked premium and digestion picks across all four models. Momentous has consolidated as the premium-athlete pick (Claude #1, Perplexity #2). Nutricost is the universal budget concentrate. The long tail (Isopure, Ghost, Orgain, Levels, Kaged, Myprotein, NutraBio, Swolverine) is heavily model-specific.
