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.

Verification
Does Tesamorelin come with a COA?
Yes — every box. Each batch of Tesamorelin is analysed by Janoshik Analytical or Freedom Diagnostic. The certificate confirms identity by mass spectrometry and purity by HPLC, and is tied to the batch number printed on the vial label. You can ask to see it before you order.

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 $16.07 per vial, sold in boxes of 10 vials at $160.71 per box (about £126.96). 2 strengths available: 10 mg, 20 mg. There is no minimum order.
What purity is your Tesamorelin?
All batches test at 99%+ purity. Every box ships with a batch-specific Certificate of Analysis from Janoshik Analytical or Freedom Diagnostic, confirming identity by mass spectrometry and purity by HPLC.
Is there a minimum order for Tesamorelin?
No. You can order a single box of 10 vials. There is no trade account, bulk commitment or minimum spend.
How is Tesamorelin shipped?
Tracked and in discreet, plain packaging, dispatched within 1–3 working days. Delivery estimates are UK 5–7 working days, EU 8–10, USA 5–8 and rest of world 10–12. Full detail is on the shipping page.
