Product Specification

Ultra-High-Potency Leech Powder (Hirudo nipponica), 600 AT-U/g

The Pinnacle of Standardized Bioactive Leech Ingredient

Ⅰ. PRODUCT OVERVIEW

Introducing our flagship Ultra-High-Potency Leech Powder, a revolutionary ingredient that redefines the upper limits of standardized natural hirudin activity. Through proprietary breeding and breakthrough stabilization technology, we consistently achieve a guaranteed minimum of 600 Anti-Thrombin Units (AT-U) per gram. This product is engineered for visionary formulators seeking to create next-generation nutraceuticals where unprecedented bioactive concentration, scientific validation, and market leadership converge.

Ⅱ. KEY SPECIFICATIONS & QUALITY ASSURANCE

Ⅲ. CORE ADVANTAGES & INNOVATION

1. Unprecedented Bioactive Density
At 600 AT-U/g, this ingredient delivers the highest commercially available concentration of natural hirudin. This enables the development of exceptionally potent, low-dosage formats that offer a compelling efficacy story and superior cost-in-use for premium positioning.

2. Proprietary "Activity-Lock" Breeding & Processing
Our advantage stems from two pillars:

• Strain Selection: A proprietary, closed-cycle breeding program selectively enhances hirudin expression in Hirudo nipponica.

• Stabilization Technology: A multi-stage, low-energy process that captures and stabilizes the bioactive peptides immediately post-harvest, preventing enzymatic degradation and maximizing final yield.

3. Designed for Advanced Delivery Systems
The ultra-fine particle size and exceptional purity make this powder ideal not only for traditional capsules but also for advanced delivery systems such as orodispersible tablets (ODTs), nano-emulsions, and high-concentration liquid extracts, where solubility and clarity are paramount.

4. Complete Regulatory & Technical Support
We provide a comprehensive Technical Dossier including full characterization, safety data, and suggested GRAS (Generally Recognized As Safe) rationale for regulatory submissions in key markets, significantly reducing your product development timeline.

Ⅳ. TARGET APPLICATIONS

• Breakthrough Single-Ingredient Supplements: Create definitive "best-in-class" products (e.g., "Hirudin-600" capsules) for the most demanding consumers in cardiovascular and metabolic health niches.

• Pharmaceutical Intermediates: High-quality, standardized starting material for further purification or as an active pharmaceutical ingredient (API) in certain jurisdictions.

• Advanced Clinical Research: The optimal candidate for pilot studies and clinical trials requiring a precisely dosed, high-potency natural anticoagulant/anti-thrombotic agent.

• Biopharmaceutical Innovation: A key raw material for R&D in drug delivery, wound healing, and medical device coatings.

Ⅴ. PACKAGING & STORAGE

• Primary Packaging: 500g or 1 kg in high-barrier, nitrogen-flushed trilaminate foil pouches with integrated oxygen scavenger and desiccant.

• Storage Instructions: For optimal long-term stability, store frozen (-20°C) or refrigerated (2-8°C). Short-term storage at controlled room temperature (≤ 25°C) is acceptable.

• Shelf Life: 36 months from manufacture when stored frozen. 24 months when stored refrigerated.
