Where to buy tesamorelin online, and how to check the seller
Lyra Vital sells tesamorelin as a lyophilized research peptide in 10mg, 15mg single vials from $64 (down to $5.93 per mg), shipped from Orlando, Florida. 6 Janoshik Analytical certificates are on record, measured purity 99.17% to 99.70%, each with its verification key. The 10mg lot was also tested in Lyra Vital's own name by Accurate Test Labs (ISO/IEC 17025:2017): 10mg 99.91%, endotoxin passed. For research use only.
How to check any tesamorelin seller, including us
- 01
The report verifies at the laboratory.
A certificate image proves nothing by itself. A Janoshik report carries a task number and key that return the lab's own copy at janoshik.com/verification/; other labs confirm by report number. If the seller cannot tell you how to verify it, treat it as unverified.
- 02
The lot matches your vial.
The batch code on the report should be the batch code on the tesamorelin vial you receive. A certificate for a different lot, or a different size filled from an untested lot, does not describe your material.
- 03
You know who ordered it.
The client line says who sent the sample. A manufacturer's test is useful; a test the seller ordered on its own retail stock, or one a buyer ordered, is stronger. Ask which you are looking at.
- 04
Identity, not just purity.
HPLC purity says how clean the sample is; mass spectrometry says it is tesamorelin at all. A purity figure without an identity result is half a test.
- 05
Endotoxin, if it matters to your work.
Bacterial endotoxin is a separate panel from purity and identity, and most research-peptide certificates do not include it. Ask for it by name.
- 06
No human-use claims.
Research peptides are sold for laboratory research. A seller that offers dosing protocols, before-and-after claims or medical advice is telling you how it treats every other rule.
What tesamorelin is sold as
Tesamorelin is a 44-amino-acid GHRH analogue with a trans-3-hexenoyl group on its N-terminus, research code TH9507. Suppliers list it under its own name; the CAS number and molecular formula on the certificate are what identify it.
Tesamorelin is a longer peptide than most in the growth-hormone category, which gives more room for truncated or deletion sequences. Purity by HPLC and identity by mass spectrometry together are the minimum; a lab report in the seller's own name, with endotoxin, is stronger.

How Tesamorelin compares
Side-by-side against the compounds researchers most often weigh it against, with price per milligram and the published certificate for each.
AOD-9604 vs Tesamorelin
An hGH fragment selected to exclude growth signaling, against a GHRH analog that deliberately drives the full axis.
CJC-1295 (no DAC) vs Tesamorelin
Truncated GHRH(1-29) against full-length GHRH(1-44). Sequence length is the whole distinction and it is routinely glossed over.
IGF-1 LR3 vs Tesamorelin
Direct IGF-1 receptor agonism versus upstream GHRH stimulation — acting at opposite ends of the same axis.
Ipamorelin vs Tesamorelin
