# Leucine Peptide Protein Powders Infinis Adds Two Classic Flavors to Protein Peptide L5 By Adam Harrie | Written with AI assistance | Published 2026-10-15 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/leucine-peptide-protein-powders References: [stack3d](https://www.stack3d.com/2026/10/infinis-protein-restock-new-flavors)  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.
