GHRH analogue research peptide

Tesamorelin GHRH Analogue | HPLC-Verified | Bio Mech

Tesamorelin is a stabilised analogue of growth-hormone-releasing hormone (GHRH(1-44)) with a trans-3-hexenoyl modification at the N-terminus that confers protection against DPP-4 degradation. This guide covers what tesamorelin is, how Bio Mech verifies every batch, and how to source tesamorelin reliably across Spain, the UK, Europe and the USA.

Reading this research reference

The information below concerns the research subject, not proof of the identity or performance of a supplied material. Check the original sources and your laboratory’s requirements; product documentation must be assessed separately for the exact batch.

What tesamorelin is and why it's studied

Tesamorelin is a 44-amino-acid synthetic peptide derived from native GHRH with a trans-3-hexenoyl group attached to the N-terminal tyrosine. The modification protects the peptide from DPP-4 cleavage and produces a substantially longer functional half-life than unmodified GHRH(1-29) or sermorelin.

Published preclinical and clinical research has explored tesamorelin in studies of visceral adipose tissue, lipid metabolism, IGF-1 axis modulation and the broader growth-hormone secretory pathway. It remains the gold-standard reference GHRH analogue in laboratory work.

How Bio Mech verifies every tesamorelin batch

No laboratory reports have yet been verified for publication against Bio Mech stock. Ask support about documentation for the exact production lot before ordering.

Janoshik Analytical is the default verification partner. Per-batch PDFs are downloadable from the lab reports page and traceable to the batch number printed on every vial cap.

Storage, reconstitution and laboratory handling

Lyophilised tesamorelin is supplied as a sterile white powder under inert atmosphere. Hold unopened vials at 2–8 °C; transfer to −20 °C only if reconstitution will not happen within 8 months. Reconstitute with bacteriostatic water for a two-month (60-day) in-use stability window under refrigeration; minimise light exposure to preserve the N-terminal tyrosine.

Most laboratories favour 2–5 mg/ml stock concentrations for ease of microlitre dispensing. Tesamorelin is sensitive to repeat freeze–thaw cycles — aliquot the full reconstituted volume before any freeze to preserve potency.

US buyers should confirm institutional research-purchasing policy before ordering. Tesamorelin is supplied strictly for research use only and is not approved for human consumption in any jurisdiction.

Tesamorelin vs CJC-1295 and ipamorelin

Researchers often compare tesamorelin with CJC-1295 (with and without DAC) and ipamorelin in growth-hormone secretory-axis panels. Tesamorelin is a stabilised GHRH analogue; CJC-1295 is a 30-residue GHRH analogue with optional DAC (drug-affinity-complex) modification for extended half-life; ipamorelin is a selective ghrelin/GHSR receptor agonist that acts on a different upstream pathway entirely.

Stocking the three from the same supplier keeps batch documentation and packaging consistent across a comparative growth-hormone secretory-axis study.

Quality signals to demand from a tesamorelin supplier

An honest tesamorelin supplier publishes a per-batch third-party COA that explicitly verifies the trans-3-hexenoyl N-terminal modification by mass spectrometry — a missing or incorrect modification is the single most common defect in cheap tesamorelin and cannot be detected by HPLC purity alone.

Frequently asked questions

What is tesamorelin?+

Tesamorelin is a stabilised 44-amino-acid GHRH analogue with a trans-3-hexenoyl modification at the N-terminus that protects against DPP-4 degradation.

Is tesamorelin safe for human use?+

Bio Mech tesamorelin is supplied strictly for in-vitro and preclinical research and is not approved for human consumption in any jurisdiction.

What HPLC purity should I expect?+

No laboratory reports have yet been verified for publication against Bio Mech stock. Ask support about documentation for the exact production lot before ordering.

How is tesamorelin reconstituted?+

With bacteriostatic water; refrigerate at 2–8 °C and use within 2 months. Aliquot before any freeze and minimise light exposure.

Do you ship tesamorelin to Spain?+

Yes — 5–18 day tracked delivery and 5–18 day Spain-wide tracked dispatch.

Do you ship tesamorelin to the UK?+

Yes, with 5–18 day tracked dispatch and VAT/customs handling included transparently at checkout.

Do you ship tesamorelin to the USA?+

Yes, with discreet tracked international dispatch in temperature-buffered packaging.

How is tesamorelin different from CJC-1295?+

Both are GHRH-axis peptides, but tesamorelin is a 44-residue stabilised analogue while CJC-1295 is a 30-residue analogue available with or without a DAC half-life extension.
