Infinis is expanding 'Protein Peptide L5' with 'Milk Chocolate' and 'French Vanilla,' giving people who use protein powder for muscle growth and recovery two staple tastes alongside its earlier dessert-led menu. The powder uses a whey-based blend with 'Lacprodan BLG-100' beta-lactoglobulin isolate and 'PepForm' leucine peptides to support training recovery and muscle growth.
Each serving provides 25g of protein and 5g of leucine, keeping the formula centered on muscle protein synthesis. The two new flavors arrive this Friday on the Infinis website, where the previous dessert options also return in the same restock.
At $64.99, the powder broadens its appeal by pairing an ingredient-forward formula with the two most familiar shake flavors. That move widens Protein Peptide L5 beyond novelty-led buying and makes it easier for repeat users to keep the same formula in a daily rotation.

What's Driving This Trend
- Functional Flavor Familiarity
- Classic flavor profiles are becoming a bridge between advanced sports nutrition formulas and everyday repeat consumption, creating room for performance products that feel less niche.
- Leucine-forward Formulas
- Higher-emphasis leucine dosing reflects growing interest in muscle protein synthesis as a visible product differentiator within crowded protein powder categories.
- Ingredient-led Fitness Nutrition
- Clinically recognizable inputs such as beta-lactoglobulin isolates and peptide blends are reshaping consumer expectations around efficacy, transparency, and premium positioning.
Who This Affects Most
- Sports Nutrition
- Protein powders with targeted recovery ingredients are expanding the category beyond general supplementation into more specialized daily training support.
- Functional Foods
- Performance-oriented powders with familiar sensory cues show how functional formats can become more habitual when efficacy and taste are balanced.
- Health and Wellness Retail
- Direct-to-consumer supplement launches centered on restocks and flavor expansion highlight opportunities for loyalty-driven merchandising in premium wellness products.
