Fenbendazole capsules (444 mg) contain a high-purity antiparasitic benzimidazole compound widely used for experimental research applications. Manufactured in the USA under stringent quality control protocols, each batch undergoes rigorous third-party testing to verify purity (>99%) and consistency. Fenbendazole acts by selectively binding to β-tubulin in parasitic organisms, disrupting microtubule formation and cellular function.

Product Usage

This PRODUCT IS INTENDED AS A RESEARCH CHEMICAL ONLY. This designation allows the use of research chemicals strictly for in vitro testing and laboratory experimentation only. All product information available on this website is for educational purposes only. Bodily introduction of any kind into humans or animals is strictly forbidden by law. This product should only be handled by licensed, qualified professionals. This product is not a drug, food, or cosmetic and may not be misbranded, misused or mislabled as a drug, food or cosmetic.

Storage Instructions

Handling and Storage Tips:

  • Keep peptides cold and away from light once received.
  • For short-term use (days to weeks), refrigeration at 4°C (39°F) is acceptable.
  • Lyophilized peptides are typically stable at room temperature for several weeks, making it suitable for moderate-term storage.
  • For long-term storage (months to years), it’s best to freeze peptides at -80°C (-112°F). Freezing optimally preserves peptide stability for extended periods.

Heat Stability During Transit

We package our temperature-sensitive products to preserve stability throughout transit. Our packaging provides insulation to minimize the effects of heat exposure, so orders remain safe during shipping - including in warmer climates and throughout the summer months.

  • Liquid Sprays: Our liquid peptide sprays, while tolerant to short-term heat, can lose potency if exposed for too long. If delivered in temperatures up to 100°F, they remain stable for up to 6 hours. For conditions exceeding 100°F or with direct sun exposure, we recommend retrieving the package within 1–2 hours to ensure optimal quality.
  • Peptide Vials: All our vial products are lyophilized (freeze-dried) to remain 100% stable for 3–4 months during shipping. Once reconstituted (mixed with bacteriostatic water), peptides must be refrigerated and remain stable for up to 30 days.
