1. Consultation & Custom Formulation
Work with our R&D team to develop a unique sports supplement formula. Our sports scientists evaluate your target market’s training needs and performance goals, whether for strength athletes, endurance competitors, or general fitness enthusiasts. We determine optimal ingredient combinations based on training phase (pre-workout, intra-workout, post-workout) and recommend clinically effective dosages that deliver noticeable results without unnecessary fillers.
2. High-Quality Ingredient Sourcing
We source premium performance ingredients with documented sports applications and verified certificates of analysis. Our procurement team secures pharmaceutical-grade proteins with specified amino acid profiles, instantized BCAAs for superior mixability, and patented performance compounds with research validation. Each ingredient undergoes stringent testing for heavy metals, microbiological contaminants, and athletic banned substances before entering production.
3. Manufacturing & Quality Testing
Your sports nutrition supplements are produced using specialized equipment designed for the unique challenges of performance ingredients. Our protein processing preserves native protein structures through low-temperature handling, while our pre-workout manufacturing implements precise microdosing of stimulants and performance compounds. Each batch undergoes sports-specific quality testing including protein content verification, amino acid quantification, dissolution rate analysis, and stimulant verification.
4. Branding & Packaging
We offer athletic-focused packaging solutions including nitrogen-flushed protein containers that maintain freshness, specialized pre-workout tubs with humidity control, and performance-minded single-serve sachets for on-the-go training. Our packaging experts help develop appropriate serving size recommendations, exercise timing instructions, and performance-focused benefit statements that resonate with fitness consumers.
