Stanozolol API Supplier India | 2 Grades | Bulk Export

Aarise Pharmaceuticals supplies stanozolol in two micronised grades, 5 micron and 30 micron, as bulk anabolic steroid API from India.

Available Stanozolol Grades

Choosing the Right Grade

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. The two micronised grades exist because particle size governs behaviour in the two main dosage forms.

Quality Documentation — What to Request

The 5 micron grade is specified where dissolution rate matters, typically aqueous suspension for injection, because the finer particle size gives a more consistent suspension and reduces settling. The 30 micron grade is generally preferred for oral tablet compression, where the coarser particle flows better through a tablet press and reduces the risk of capping. Specify the grade at enquiry rather than after delivery, since converting between grades requires re-milling and re-testing. Request particle size distribution, assay by HPLC, loss on drying, sulphated ash and related substances.

Import, Licensing & Logistics

Stanozolol is controlled in the majority of markets. Import licensing is required in most destinations and rests with the buyer. Requirements differ substantially between the EU, North America and Asia, so confirm your national classification before requesting a commercial quotation.

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.

Ordering Stanozolol API

Packaging runs from 250 g sealed aluminium bags to 5 kg drums, with larger commercial quantities quoted on request. Specify the grade, quantity and destination at enquiry so the quotation reflects the correct MOQ and documentation set. Mixed consignments across grades in this range ship as a single shipment.
