Somatropin (HGH) research lyophilizate — wholesale from India

Regulatory positioning: Rx-only · Approved drug. Recombinant human growth hormone (Somatropin) is an approved drug in most jurisdictions. Rx-only and controlled in many markets. Subject to buyer compliance with applicable controlled-substance and Rx regulations.

Overview

Somatropin, also referenced as recombinant human growth hormone (HGH) or rhGH, is a 191-amino-acid recombinant protein that matches the sequence of endogenous human growth hormone. SPK Pharma India supplies Somatropin as a research-grade lyophilizate, positioned for in-vitro growth hormone receptor research, cell-based signalling studies, and analytical reference-standard work. The product is supplied in the raw lyophilized form, not as a finished pen kit or finished dosage form, and is intended for laboratory, analytical, and reference-standard buyers that require the bulk research material with full documentation.

Specifications

Research context

Somatropin is the reference-standard research reagent in growth hormone receptor biology. The growth hormone receptor (GHR) is a type I cytokine receptor that signals through the JAK2-STAT5 pathway, with downstream effects on IGF-1 production, cellular proliferation, and metabolic gene expression in defined cell-based systems. In-vitro receptor-binding assays, JAK2-STAT5 phosphorylation studies, and cell proliferation assays in GHR-expressing cell lines are the typical research applications.

The recombinant 191-amino-acid form supplied by SPK Pharma India matches the published somatropin sequence, and the lot-matched COA includes peptide mapping, N-terminal sequencing, and size-exclusion chromatography data to confirm identity and structural integrity. SPK Pharma India does not make therapeutic, clinical, diagnostic, or dosing claims for this product. The compound is supplied strictly for in-vitro research, analytical method development, and reference-standard work, and is not supplied as a finished pen kit or finished dosage form.

For researchers new to the compound, the standard analytical reference points are CAS 12629-01-5, the 191-amino-acid backbone, the approximate molecular weight of 22,124 g/mol, the lyophilized powder form, and the documented purity threshold (≥99% HPLC). The full amino acid sequence and the peptide map are disclosed on the lot-matched COA and on the product specification sheet.

Packaging and supply

• 10 IU research vial — for method development, receptor-binding assays, and reference-standard qualification. Standard MOQ: 5 vials.
• 50 IU research vial — for ongoing research programmes with higher per-assay demand. Standard MOQ: 2 vials.
• 100 IU research vial — for recurring programmes and reference-standard stock. Standard MOQ: 2 vials.
• Bulk pack — on application, for annual supply contracts and recurring orders.

Distributor pricing is available on application. Annual supply contracts with scheduled recurring dispatch are available for repeat buyers. Lead time for in-stock SKUs is typically 5 business days from purchase order confirmation; lead time for scheduled production is typically 4 to 6 weeks.

Quality and documentation

Every lot of Somatropin ships with a lot-matched Certificate of Analysis documenting identity (mass spectrometry, peptide mapping, N-terminal sequencing), purity (HPLC — both size-exclusion and reverse-phase), appearance, lot number, and synthesis batch reference. A representative sample of every lot is independently verified by a third-party analytical laboratory before release. MSDS is supplied with every shipment. The COA template, the lot-traceability workflow, and the third-party verification scope are documented on the Quality page.

Storage and handling

• Store at 2°C to 8°C in the original sealed container. Do not freeze.
• Protect from light.
• Allow the sealed container to reach room temperature before opening, to avoid condensation.
• Reconstitute in sterile, low-endotoxin research-grade water or in a mild buffer at the working concentration required by the assay.
• Do not refreeze once reconstituted; aliquot and store at working concentration.
• For protein work, avoid vigorous vortexing; allow gentle dissolution to minimise aggregation.

Shipping

Somatropin is shipped lyophilized in sealed vials within temperature-validated packaging (2°C to 8°C) with cold-chain handling. International lanes are routed through dedicated life-science logistics partners with continuous temperature monitoring. Standard dispatch is within 5 business days of purchase order confirmation. SPK Pharma India ships to the United States, the European Union, the United Kingdom, Canada, MENA, APAC, and LATAM. Full export documentation, including commercial invoice, packing list, certificate of origin, COA, and MSDS, is included with every shipment. Destination-specific documentation is supported on request.

Compliance

Recombinant human growth hormone (Somatropin) is an approved drug in most jurisdictions. Rx-only and controlled in many markets. Subject to buyer compliance with applicable controlled-substance and Rx regulations. SPK Pharma India does not make therapeutic, clinical, diagnostic, or dosing claims for this product. The buyer is responsible for end-use classification in the destination jurisdiction, for the appropriate Rx / licence / controlled-substance documentation, and for ensuring that downstream handling is consistent with the regulatory positioning stated above.
