Tesamorelin API Supplier India | CAS 218949-48-5 | Bulk Peptide API

Tesamorelin is a 44-amino-acid synthetic analogue of human growth hormone-releasing factor. It is supplied as a lyophilized peptide and is among the more demanding peptide APIs to ship internationally because the cold chain cannot be broken.

Tesamorelin Specifications

Quality Documentation — What to Request

Because Tesamorelin is a long-chain peptide, purity assessment differs from small-molecule APIs. Procurement teams normally ask for HPLC purity, peptide content determined by amino acid analysis or nitrogen determination, acetate content, and a water content figure by Karl Fischer. The peptide content number matters commercially: a vial quoted on gross weight rather than net peptide content will not compare like-for-like against another supplier.

Import, Licensing & Logistics

Cold-chain shipment at -20°C with temperature logging is standard. Customs clearance for lyophilized peptides can be slower than for conventional APIs in several markets, so build clearance time into your production schedule. Confirm whether your destination classifies GRF analogues as a controlled or restricted import.

Who Buys Tesamorelin API

Peptide formulation developers, research institutions and pharmaceutical companies developing GRF analogue preparations.

Peptide Content Versus Gross Weight

Tesamorelin is a 44-amino-acid chain, long enough that peptide content and gross weight diverge significantly. Material quoted on gross weight can contain fifteen to twenty per cent counter-ion, residual solvent and water, none of which is active. Peptide content by amino acid analysis or nitrogen determination is the only figure that tells you what you have actually bought, and two quotations cannot be compared without it.

Stability, Storage & Retest

Lyophilized peptides are stable at minus twenty degrees Celsius but degrade measurably at ambient temperature over weeks rather than months. The cold chain must hold from despatch to receipt, and a temperature logger in the consignment is the only way to verify it did. Once reconstituted, stability is measured in days. Water content by Karl Fischer matters because residual moisture accelerates degradation during storage.

Export Process & Lead Time

Peptide consignments require cold-chain air freight with temperature logging, which restricts routing and carrier options and raises freight cost substantially relative to ambient shipment. Customs clearance for lyophilized peptides is slower than for conventional APIs in several markets because the classification is less familiar to inspectors, and a consignment held at ambient temperature during a clearance delay may arrive out of specification. Build clearance time into planning and confirm the destination classification before despatch.

Incoming Goods Inspection

Incoming checks should cover appearance, HPLC purity against the supplied chromatogram, peptide content and water content. Peptide content is the figure that determines what you have actually bought: material quoted on gross weight rather than net peptide content can differ by fifteen to twenty per cent from what the label implies, and that difference will not appear in a purity figure.

Frequently Asked Questions

What documentation comes with Tesamorelin 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 Tesamorelin 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.
