Pepaid™ by HANFEI: The NEO Generation of Amino Acid Biostimulants

Pepaid™, a sub-brand of HANFEI Biotech, represents a new origin in fertilizer technology. Founded in 2005, HANFEI specializes in high-quality hydrolyzed collagen peptides for human nutrition. With 15,000 tons of annual capacity and pharmaceutical-grade quality control, we are now bringing this purity and precision to agriculture, redefining the source of crop nutrition.

NEO-Growth Bioactivation

Synergistic amino acids and peptides activate natural growth signals, enhancing root strength and stress resistance. This bio-activation mechanism ensures crops absorb nutrients faster and perform better under stress, delivering new efficiency that surpasses traditional fertilization methods.

Neo sustainability model of pepaid

NEO-Sustainability Model

Made from bio-based, biodegradable ingredients, Pepaid™ supports organic and regenerative farming. By protecting soil health and reducing chemical residues, we are building a new ecology for sustainable agriculture where productivity and environmental stewardship go hand in hand.

Together, these mechanisms form the three pillars of Pepaid™: New Ecology · New Efficiency · New Origin — the reason we call Pepaid™ the NEO generation of amino acid fertilizers.

Core Products

Modern agriculture needs more than NPK. Our amino acid fertilizers support stronger roots, plant defense, and better input efficiency.

Common Questions

Discover the science behind our NEO-generation technology and find answers to how plant-based nutrition can optimize your crop performance.

Pepaid™ represents the NEO-Generation of Amino Acid Fertilizer, developed around controlled enzymatic hydrolysis, peptide preservation, and application-oriented formulation.

Instead of offering generic amino acid inputs, Pepaid™ provides different product series based on raw material source, molecular weight, free amino acid profile, and target use. This allows formulators and distributors to choose the right solution for stress recovery, nutrient uptake, root development, soil health, or customized NPK and micronutrient blends.

Our focus is consistent quality, functional peptide activity, and flexible B2B formulation support for global agriculture markets.

Absolutely. Our FP90 fermentation product contains natural organic acids (lactic and acetic acid) that act as chelating agents. They help adjust soil pH and unlock fixed nutrients in the soil. This significantly improves the efficiency of your phosphorus fertilizer and potassium applications, ensuring crops absorb more nutrients with less waste.

Yes, stress resistance is a core benefit of our Amino Acid Biostimulants. For example, our soy-based EP60P is rich in natural isoflavones and arginine. These compounds function like “biological shields,” stimulating root development and enhancing the crop’s antioxidant capacity against drought, salinity, and UV damage.

Yes, Pepaid™ products are highly compatible. They work synergistically with macro-nutrients. For instance, mixing our amino acid formulas with a fertilizer with potash can enhance potassium uptake and transport within the plant. This synergy boosts overall crop performance, improving both fruit quality and yield.

As a leading Amino Acid Biostimulant China Supplier, Pepaid™ combines advanced biotechnology with reliable supply chain management.

We offer differentiated solutions—from root stimulation to soil conditioning—backed by strict quality control and professional technical support for global B2B partners.
