About Tesamorelin
What is Tesamorelin?
Overview
What is Tesamorelin?
Tesamorelin is a synthetic 44-amino-acid analogue of human growth-hormone-releasing hormone, modified with an N-terminal trans-3-hexenoyl group that improves resistance to enzymatic degradation. Supplied as a lyophilised powder, boxed in tens, for laboratory research use only. It is stocked in three strengths, a tesamorelin 5 mg, 10 mg and 20 mg vial, and the tesamorelin peptide on this page is the same compound described in the published trial literature.

These are catalogue target specifications, not batch results. The 99%+ purity figure is the specification we buy to. The authoritative figures for any particular box are the ones printed on that box’s Certificate of Analysis, which is lot-specific. What research grade actually means explains the difference. Terms such as HPLC purity and net peptide content are explained in the peptide glossary.
We make no “third-party verified” claim for a batch unless the matching report is supplied with it. Ask for the current COA for the lot in stock before you order — we will send it.

Storage & reconstitution
Handling
How should Tesamorelin be stored and reconstituted?
Sealed vials tolerate ambient temperature in transit and keep at −20 °C beyond that. Reconstitute slowly down the vial wall, swirl rather than shake, then refrigerate at 2–8 °C and aliquot before freezing.
Why each of those matters, and what a freeze–thaw cycle actually costs: peptide handling and storage reference. How long a mixed vial keeps: reconstituted peptide shelf life.
What it is researched for
Research Context
What is Tesamorelin researched for?
Below is a plain-English summary of what published research has investigated, and what it has found. These are descriptions of research activity and published results. They are not claims about what Tesamorelin does, and nothing here is a statement that it is safe or effective for any purpose.
Growth hormone axis stimulation
Tesamorelin is a full-length GHRH analogue, carrying the complete 44-residue signal rather than a fragment. The hexenoyl group on the N-terminus protects it from the enzyme that would otherwise clear it within minutes. 1
Visceral fat research
Its approved clinical use concerns reduction of excess visceral abdominal fat in a specific patient group, and the majority of the clinical literature sits there. 12
Comparative GHRH pharmacology
As the most complete GHRH analogue available, it serves as the reference point when studying shorter analogues such as CJC-1295 and Modified GRF 1-29.

Batch COA
Verification
Does Tesamorelin come with a COA?
Yes — every box. Each batch of Tesamorelin is analysed by an independent third-party laboratory, and the certificate is tied to the batch number on the vial label.

Questions & answers
Questions
Tesamorelin questions, answered
How does Tesamorelin differ from native GHRH?
Tesamorelin retains the full 44-residue GHRH sequence but adds a trans-3-hexenoyl group at the N-terminus. Native GHRH is rapidly cleaved by dipeptidyl peptidase-4; the added group slows that degradation considerably while preserving receptor binding.
How much does Tesamorelin cost?
Tesamorelin starts at $11.50 per vial, sold in boxes of 10 vials at $115.00 per box (about £86.16). 3 strengths available: 5 mg, 10 mg, 20 mg. There is no minimum order.
Can I buy Tesamorelin 10mg vials in the UK?
Yes. Tesamorelin 10mg comes in boxes of 10 vials at $160.71 per box ($16.07 per vial, about £120.40 per box), sent tracked to UK addresses. There is no minimum order.
Do you ship Tesamorelin to the US?
Yes, to all 50 states. Tesamorelin ships FedEx tracked from our UK stock or direct from our verified manufacturer, arriving 5 to 8 working days after dispatch, and is billed in US dollars from $11.50 per vial. We hold no US stock. If US customs seize an order, we reship it once at no cost. Our tesamorelin US guide covers FDA status and US shipping in full.
How is Tesamorelin shipped to the UK and USA?
Tracked to the UK, USA, EU and worldwide, in plain packaging, dispatched within 1–2 working days. Country-by-country estimates are on the shipping page.
