Products Description
Enclomiphene Citrate 25mg is an orally administered, potent nonsteroidal estrogen receptor antagonist, belonging to the pure trans isomer of clomiphene. This product works by selectively blocking estrogen receptors in the brain, relieving negative feedback inhibition and prompting the pituitary gland to secrete more luteinizing hormone (LH) and follicle-stimulating hormone (FSH), thereby stimulating the natural production of endogenous testosterone in the testes. Unlike traditional testosterone replacement therapy, the 25mg dose of enclomiphene increases testosterone levels while maintaining normal sperm concentration, making it ideal for men who wish to improve symptoms of low testosterone (such as fatigue, low libido, and muscle loss) and who desire fertility. Common dosages range from 12.5mg to 25mg.

Product Features
I. Precise Action, Natural Efficacy
Enclomiphene citrate 25mg is the pure trans isomer of clomiphene, eliminating the cis isomer component in traditional clomiphene that is prone to causing side effects. It promotes the natural production of endogenous testosterone by stimulating the body to produce luteinizing hormone and follicle-stimulating hormone.
| Parameter | Data |
|---|---|
| Onset of Action | Significant improvement observed after 14 days of continuous use |
| Maintenance Range | Serum total testosterone maintained at 400-700 ng/dL |
2.Preservation of Fertility
Unlike traditional testosterone replacement therapy, this product maintains sperm concentration within the normal range while increasing testosterone levels. Studies have confirmed that sperm parameters in patients using enclomiphene are not negatively affected, while patients using testosterone gel experience significant inhibition of spermatogenesis. This characteristic makes it particularly suitable for men who wish to increase their fertility.
3. Reversible Effect After Discontinuation
The half-life of this product is approximately 10 hours, and its effects are reversible. After discontinuation, hormone levels typically return to pre-treatment levels naturally within a few weeks, without the long-term suppression seen after discontinuation of traditional testosterone replacement therapy. One study showed that testosterone levels returned to baseline within 28 days after discontinuation.
4. Oral Dosage Form, Stable Blood Concentrations
It is administered orally in capsule form once daily. Studies show that a stable blood concentration can be achieved at a dose of 25 mg, and compared to testosterone gel, enclomiphene citrate 25mg does not cause an abnormal increase in dihydrotestosterone, maintaining a more balanced hormone conversion ratio.

Supply Chain Advantage
1. Standardized Management of Raw Materials
We implement strict standardized management of raw material harvesting (production) batches:
- Production Batch Control: Each batch of raw materials has a unique batch number, recording production time, process parameters, and other information to ensure traceability.
- Active Ingredient Control: Raw material purity is required to reach 99% or higher, and the cis isomer (Z-isomer) content is controlled below 0.10%. This is the core indicator for raw material release.
- Quality Inspection Release: Each batch of raw materials must pass multiple tests, including HPLC purity testing, loss on drying, residue on ignition, and heavy metal testing, before being put into storage and used.
2.Storage and Preservation:
Enclomiphene citrate has strict requirements for storage conditions, mainly affected by high temperature, humidity, and light. We take the following measures:
| Measure | Specific Requirements |
|---|---|
| Low Temperature Storage | Raw materials are stored in a 2-8°C refrigerated environment upon receipt; long-term storage can be kept at -20°C or below |
| Dryness Control | Warehouse maintains a low-humidity environment; use sealed containers equipped with desiccants to prevent moisture absorption |
| Light Protection Packaging | Use light-protective packaging materials such as amber glass bottles or aluminum foil bags to prevent photodegradation |
| Seal Management | Immediately seal after opening; solution forms can be aliquoted for storage to reduce repeated sampling |
3.Traceability System
We have established a full-process batch traceability system:
- Raw Material Batch Traceability: Each batch of raw materials is registered upon entry into the warehouse with the supplier's batch number, production date, and COA number, allowing traceability back to the source of production.
- Quality Inspection Record Preservation: COA test reports for each batch of products are archived for future reference, including data on purity, impurities, moisture, etc.
- Sample Retention Management: Samples of each batch of raw materials are retained for retesting within their expiration date.
- Document Support: A complete set of quality documents, including batch records, COA analysis certificates, and MSDS, can be provided.

4.Addressing Core Customer Concerns
| Customer Concern | Our Solution |
