Drostanolone API Supplier India | 2 Grades | Bulk Export

Aarise Pharmaceuticals supplies drostanolone propionate and drostanolone enanthate as bulk anabolic steroid APIs from India.

Available Drostanolone Grades

Choosing the Right Grade

Drostanolone is a 2-alpha methylated dihydrotestosterone derivative. The 2-alpha methyl group prevents metabolic reduction at that position, which is the structural feature distinguishing it from unmodified DHT derivatives. Propionate is the short-acting ester; enanthate extends release considerably.

Quality Documentation — What to Request

Request assay by HPLC, free steroid content, melting point range, related substances and residual solvents. As with other esterified anabolic APIs, free parent steroid content is the figure that determines whether the release profile of the finished preparation will match specification.

Import, Licensing & Logistics

Drostanolone esters are controlled substances in most jurisdictions. An import licence is required in the majority of destinations and obtaining it rests with the buyer.

2-Alpha Methylation

The 2-alpha methyl group on drostanolone blocks metabolic reduction at that position, which is the structural feature distinguishing it from unmodified dihydrotestosterone derivatives. Propionate and enanthate esters give short and extended release respectively. Free parent steroid content remains the figure that determines whether the finished preparation will match its intended release profile.

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 Drostanolone 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.
