Methenolone Enanthate API Supplier India | CAS 303-42-4 | Bulk Steroid API
Methenolone Enanthate API Supplier & Exporter — India
CAS 303-42-4 | Bulk sourcing for pharmaceutical companies, distributors and qualified importers.
Methenolone Enanthate, widely referenced by the brand name Primobolan, is the enanthate ester of methenolone. It is a 1-methylated dihydrotestosterone derivative, and the 1-methyl group is what prevents the hepatic breakdown that affects unmodified DHT derivatives.

Quality Documentation — What to Request
Standard documentation covers assay by HPLC, related substances and residual solvents. The practical issue with this molecule is not analysis but authenticity: Methenolone Enanthate is among the more frequently substituted steroid APIs in the grey market, commonly with cheaper testosterone esters. Insist on a batch-specific CoA traceable to the named manufacturer and, for first orders, consider independent verification.
Import, Licensing & Logistics
Genuine Methenolone Enanthate has materially more constrained availability than common steroid esters, and lead times are longer as a result. Confirm current sourcing before building it into a production schedule. Controlled substance classification applies in most markets.
Who Buys Methenolone Enanthate API
Licensed pharmaceutical manufacturers formulating injectable oil-based preparations.
Supply Constraint and Substitution Risk
Genuine methenolone enanthate has materially tighter availability than common steroid esters, and lead times reflect that. The scarcity drives substitution: this is one of the more frequently adulterated compounds in the grey market, usually with cheaper nandrolone or testosterone esters. For a first order from any source, independent verification against a reference standard is worth the cost, and the batch certificate should trace to a named manufacturer.
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.
