FAQS

• How is HCG used to trigger ovulation in ART/IVF

  A single injection of HCG (typically 5,000–10,000 IU) is administered to mimic the natural LH surge and trigger final oocyte maturation, with oocyte retrieval scheduled approximately 34–36 hours later. It is also used for luteal phase support and for male hypogonadism. Dosing should always be individualized by the treating physician.
• Is VBIO HCG urinary-derived or recombinant? How do you ensure purity and batch-to-batch consistency?

  Our HCG is extracted and highly purified from the urine of pregnant women, retaining the natural glycosylation profile that closely mimics endogenous hCG. It is manufactured under GMP-compliant conditions with full in-process controls — including in vivo bioactivity assay, sterility and endotoxin testing — ensuring high purity and consistent potency across batches.
• What are the recommended storage conditions and shelf life?

  Store the lyophilized powder at 2–8 °C, protected from light. Once reconstituted, the solution should be used promptly and not stored for reuse. The product remains stable throughout its labeled shelf life under the recommended conditions, and is shipped under validated cold-chain to preserve potency.
• What presentations are available, and what quality certifications does the product hold?

  HCG is supplied as a lyophilized powder with solvent, available in multiple potencies (e.g. 1,000–10,000 IU per vial), with packaging customizable upon request. It is produced under GMP certification, and we can provide a Certificate of Analysis (COA) and full technical/regulatory documentation to support your registration needs.
