Stanozolol API Supplier India | CAS 10418-03-8 | Bulk Steroid API

Stanozolol is structurally unusual among steroid APIs: a pyrazole ring is fused to the A-ring in place of the 3-keto group found in most of this class. That substitution makes the molecule practically insoluble in water and unusually stable, which is why it survives oral formulation where many steroid APIs do not.

Stanozolol Specifications

Quality Documentation — What to Request

Because Stanozolol is practically water-insoluble, dissolution and particle size matter more than they do for oil-soluble esters. Request particle size distribution alongside the standard assay by HPLC, loss on drying, sulphated ash and related substances. If the material is intended for an aqueous suspension, the particle size specification should be agreed before the order rather than after delivery.

Import, Licensing & Logistics

Controlled in the majority of markets. Import licensing is required in most destinations and rests with the buyer. Confirm your national classification before requesting a commercial quotation, as requirements differ substantially between the EU, North America and Asia.

Who Buys Stanozolol API

Licensed pharmaceutical manufacturers producing oral or suspension preparations under appropriate authorisation.

Micronised Grade Selection

The 5 micron grade is specified where dissolution rate governs performance, typically aqueous injectable suspension, because the finer particle gives a more consistent suspension with less settling. The 30 micron grade flows better through a tablet press and reduces capping risk in oral solid dose. Converting between grades requires re-milling and re-testing, so specify the grade at enquiry rather than after delivery.

Stability, Storage & Retest

Esterified anabolic APIs are chemically stable as dry powders but hydrolyse slowly in the presence of moisture, which regenerates the parent steroid and shifts the release profile of the finished preparation. Store sealed with the original desiccant, and do not decant into secondary containers before use. Retest intervals are typically set at 24 to 36 months depending on the ester, and the retest date rather than a manufacture date should appear on the Certificate of Analysis.

Export Process & Lead Time

Controlled substance consignments require an import licence issued in the destination country before despatch, and in most cases a matching export authorisation from the Indian authorities. Build four to eight weeks into your schedule for this, since the export authorisation cannot be applied for until the import licence is issued. Air freight is standard; sea freight is rarely used for controlled APIs because of the extended chain-of-custody exposure.

Incoming Goods Inspection

Your incoming goods check should cover appearance against the specification, identification by IR or HPLC retention time against a reference standard, and assay. For esters, free parent steroid content is worth running on first receipt from any new source even if the Certificate of Analysis reports it, because this is the parameter that most often differs between the certificate and the material.

Frequently Asked Questions

What documentation comes with Stanozolol API?

Batch Certificate of Analysis, product specification and SDS where available for the specific source, plus export documentation including country of origin certificate for international consignments.

What is the minimum order quantity?

MOQ depends on specification, packaging and destination. Send your requirement and we will confirm the applicable minimum with your quotation.

Can you ship Stanozolol API to my country?

Import permissions differ by destination and several markets restrict this material. Confirm your national requirements before ordering and we will advise whether we can supply into that territory.

How is pricing determined?

Pricing reflects quantity, specification, packaging and destination. Send your full requirement rather than a quantity alone so the quotation is accurate.
