- Product Description
High-purity pregnenolone powder, providing scientific-grade hormone precursors for global health and functional formulations
Shaanxi Hongda, one of China's most professional raw material suppliers, provides high-quality pregnenolone powder. This product is a white crystalline powder with a purity ≥98% (HPLC). Pregnenolone, as a common precursor to all steroid hormones (such as DHEA, progesterone, and cortisol), is known as the "mother of hormones" and is an important intermediate in the synthesis of drugs such as progesterone and finasteride. It is also used in the synthesis of steroidal drug intermediates and steroidal drugs.
Shaanxi Hongda utilizes its core "plant-derived directed biotransformation + multi-stage recrystallization" technology to ensure a purity greater than 99.0% (HPLC). We provide not only raw materials, but also the best raw materials for the "menopausal management" and "biohacking cognitive enhancement" markets. Furthermore, Shaanxi Hongda's products possess authoritative certifications such as cGMP, FDA, and EU organic certification, and can be directly sold to major markets such as the United States, the European Union, Canada, and Australia.

Advantages of Pregnenolone:
1. Extremely High Biohomogeneity and Molecular Chirality: Hongda performs batch-to-batch optical rotation and LC-MS verification to ensure that the molecular configuration is completely consistent with naturally secreted hormones in the human body.
2. Ultra-micro Modification for Neuroprotection: We have developed an "ultra-micro powder" specification, which improves the efficiency of crossing the blood-brain barrier by 40% compared to ordinary particles, making it particularly suitable for developing high-end formulations targeting cognitive improvement and mood regulation.
3. 100% Plant-Based and Solvent-Free: Hongda insists on targeted conversion from natural diosgenin, non-petrochemical synthesis. Adhering to the latest ICH Q3C standards, it completely eliminates harmful solvent residues such as benzene and methanol, helping your brand easily pass European and American "clean label" audits.
4. Comprehensive Testing: Each batch of product includes HPLC, GC-MS, and 1H-NMR test reports to ensure batch uniformity.
5. Multiple international certifications: All our products have obtained FDA, EU organic certification, cGMP, ISO9001, ISO22000, ISO14001, Halal certification and Kosher certification.

FAQs:
Q: Does your pregnenolone come from nature or synthetically?
Our semi-synthetic technique uses diosgenin from wild yam and targeted biotransformation. Molecular structure is 100% identical to genuine human hormones (biohomogeneous), and industrial supply is stable and large-scale.
Q: How do you improve the stability of pregnenolone in oil-based formulations (such as soft capsules)?
A: Hongda can provide you with an "oil-pre-soluble grade" solution. We suggest your R&D team use light-protected encapsulation technology to ensure that the activity does not decrease during storage.
Q3: How are the purity and test reports of the product guaranteed?
Each batch of our pregnenolone includes an HPLC report, GC-MS component spectrum, and 1H-NMR structural confirmation from a third-party lab in a GMP-certified facility, indicating ≥98% purity.
Q4: Are there additives or fillers?
100% pure pregnenolone crystalline powder, no fillers, sweeteners, or preservatives.
Q5: Suitable formulations?
Powder fineness ≤12µm, suitable for various processes such as capsule filling, tablet compression, functional beverage emulsification, and skincare matrix emulsification.
Q6: What is the minimum order quantity?
Bulk order minimum 1kg, also available in 25kg paper drums or customized small packaging.
Q7: How can I obtain samples for formulation verification?
A 100g free sample is provided (subject to subsequent large orders), accompanied by a complete test report.
Q8:What if the batch doesn't fulfill quality standards?
Following the report, our technical support staff will investigate within 48 hours. After confirmation, we will replace the batch or refund and send a quality analysis report.
