About Tesamorelin (research peptide supply)
Tesamorelin is a synthetic 44-amino-acid peptide analog of growth hormone-releasing hormone (GHRH 1-44), modified with an N-terminal trans-3-hexenoyl group that improves stability against enzymatic degradation. Velora Research supplies tesamorelin as a lyophilized research peptide for in vitro and preclinical investigation by qualified laboratories and research professionals.
Every Tesamorelin 10mg vial supplied by Velora is independently verified by a third-party analytical laboratory using high-performance liquid chromatography (HPLC) and mass spectrometry. The batch-specific Certificate of Analysis is published on our COAs page and linked from this product page so researchers can confirm identity, purity, and molecular integrity before placing the compound into a study.
How tesamorelin behaves in research models
Published research describes tesamorelin as a GHRH receptor agonist that, in preclinical and clinical models, binds pituitary somatotroph cells and stimulates endogenous growth hormone (GH) secretion in a pulsatile, physiologic pattern. Downstream, this is associated with elevations in insulin-like growth factor 1 (IGF-1).
- Receptor target: GHRH receptor (GHRHR) on pituitary somatotrophs.
- Class: GHRH analog — distinct from growth-hormone secretagogues such as ipamorelin, GHRP-2, and GHRP-6, which act on the ghrelin receptor.
- Half-life: ~25–40 minutes in published clinical data, with sustained downstream effects on IGF-1.
- Discovery and development: Originally developed by Theratechnologies. Tesamorelin acetate is the active ingredient in EGRIFTA SV®, an FDA-approved injectable for the reduction of excess abdominal visceral adipose tissue in HIV-infected patients with lipodystrophy.
EGRIFTA SV® is a registered trademark of Theratechnologies. Velora Research’s Tesamorelin product is a research peptide supplied for in vitro and preclinical investigation only and is not affiliated with, endorsed by, or equivalent to EGRIFTA SV®. It is not for human use.

Tesamorelin cost & availability
Velora Research lists Tesamorelin 10mg at a transparent, single-tier price so research buyers can plan procurement without negotiating per inquiry:
| Vial size | Tesamorelin cost (USD) | Best for |
| 10mg | $60.00 | Pilot studies, receptor-binding assays, single-protocol pilots, and most preclinical research designs |
Tesamorelin cost can vary widely across research-peptide suppliers — from under $50 for vendors that don’t publish testing data, to several hundred dollars for clinical-grade Egrifta SV®. Velora’s $60 price reflects a research-grade compound that is independently HPLC- and mass-spec-verified at ≥99% purity, with a batch-specific COA accessible from the product page. Free US shipping applies on orders over $200, and most orders ship within 1–2 business days.
Why qualified researchers buy Tesamorelin from Velora Research
In a category where vendor quality varies dramatically, five things separate Velora Research from the field:
- Batch-level third-party COA. Each lot of Tesamorelin peptide is verified by an independent analytical lab using HPLC for purity and mass spectrometry for identity; the COA is downloadable from the product page and tied to the batch number printed on the vial.
- ≥99% HPLC-verified purity. Identity, purity, and molecular integrity confirmed before any batch is released for sale.
- Documented production protocols. Lyophilized under controlled conditions, sealed in inert atmosphere, traceable from synthesis through shipment.
- US-based 2-day shipping with cold-chain handling. Free over $200; orders processed within 1–2 business days.
- Compliance-first sales policy. Sales restricted to qualified laboratories, institutions, and research professionals. Research-use-only terms acknowledged at checkout.
Reconstitution & storage guidance (research use)
Velora Research’s Tesamorelin ships as a lyophilized powder. For in vitro studies, researchers typically reconstitute with bacteriostatic water (0.9% benzyl alcohol) at a concentration matched to the assay protocol. A common pilot ratio for a 10mg vial is 2 mL of BAC water, yielding a 5 mg/mL stock solution — adjust per your study design.
- Pre-reconstitution: store sealed at -20°C in a dry, dark environment. Avoid freeze-thaw cycles, which can degrade peptide integrity.
- Post-reconstitution: refrigerate at 2-8°C and use within the stability window established by the study protocol. Single-use aliquots reduce the risk of repeat exposure to room temperature.
- Handling: reconstitute and aliquot under sterile lab conditions with appropriate PPE.
Velora Research supplies bacteriostatic water as a separate product. Please refer to the peer-reviewed literature for protocol-specific reconstitution and handling parameters.
Tesamorelin vs. Sermorelin vs. Ipamorelin — research-context comparison
Researchers evaluating Tesamorelin for purchase often compare it to other growth-hormone-axis research peptides. Summary of how the three differ at the mechanism level, drawn from published research:
| Attribute | Tesamorelin | Sermorelin | Ipamorelin |
| Class | Stabilized GHRH (1-44) analog | Native GHRH fragment (1-29) | Selective GHRP (ghrelin receptor) |
| Receptor target | GHRH receptor | GHRH receptor | Ghrelin / GHS-R1a |
| Sequence length | 44 amino acids | 29 amino acids | 5 amino acids |
| Half-life | ~25–40 min | ~10–20 min | ~2 hours |

Frequently Asked Questions
Is Tesamorelin the same as EGRIFTA SV®?
No. EGRIFTA SV® (tesamorelin acetate, Theratechnologies) is an FDA-approved injectable medication for HIV-associated lipodystrophy. Velora Research supplies tesamorelin as a research peptide for in vitro and preclinical investigation only. The two products are not interchangeable; Velora’s product is not a clinical or therapeutic product and is not for human use.
What is the tesamorelin cost at Velora Research?
Velora Research lists Tesamorelin 10mg at $60.00 USD. Free US shipping applies on orders over $200. The tesamorelin cost reflects a research-grade compound with batch-specific HPLC and mass-spec verification — the COA is downloadable from the product page.
Can I buy tesamorelin for human use?
No. The tesamorelin sold by Velora Research is supplied strictly for in vitro and preclinical research conducted by qualified laboratories and research professionals. Purchasers confirm research-use-only intent at checkout. For any clinical application, patients should consult a licensed physician about EGRIFTA SV®, which is a distinct, FDA-approved product.
How is Velora's tesamorelin peptide verified?
Every batch is independently tested by a third-party analytical laboratory using high-performance liquid chromatography (HPLC) for purity and mass spectrometry for identity confirmation. The Certificate of Analysis is published on our /coas/ page and linked from the product page by batch number, so each vial can be traced to its specific test report.
How should I store Tesamorelin 10mg?
Store the lyophilized vial sealed at -20°C in a dry, dark environment until reconstitution. Once reconstituted with bacteriostatic water, refrigerate at 2-8°C and use within the stability window established by the research protocol. Avoid repeat freeze-thaw cycles.
How does tesamorelin compare to sermorelin?
Both are GHRH-receptor agonists, but tesamorelin is a longer 44-amino-acid analog with an N-terminal modification that improves enzymatic stability, while sermorelin is the unmodified 1-29 fragment of native GHRH with a shorter functional half-life. Tesamorelin is FDA-approved as EGRIFTA SV® for a specific clinical indication; sermorelin is not currently approved. Both are supplied by Velora Research as research peptides only — not for human use.
How does tesamorelin compare to ipamorelin?
Tesamorelin and ipamorelin act on different receptors. Tesamorelin binds the GHRH receptor on pituitary somatotroph cells; ipamorelin is a selective ghrelin-receptor (GHS-R1a) agonist with a different signaling profile. In research literature the two are sometimes investigated together to model concurrent GHRH and GHRP signaling. Both are supplied by Velora as research peptides only.
Do you ship tesamorelin internationally?
Velora Research accepts international orders for laboratory research use only. Buyers are responsible for ensuring compliance with all applicable local, state, and national regulations in their jurisdiction prior to purchasing.
