What is — Tesamorelin
Tesamorelin (Tesamorelin acetate) is a synthetic peptide supplied by Peptworks as a lyophilized 10 mg vial for laboratory Research Use Only (RUO). It is a stabilized analog of human growth hormone-releasing hormone (GHRH) and is used as a research reagent and reference material. It is not a medicine, supplement, cosmetic or medical device, and is not for human or animal consumption. Available as bulk unbranded vials (white-label), held in stock inside the EU.
In research models, Tesamorelin acts as an agonist analog of GHRH. It binds GHRH receptors on pituitary somatotroph cells, where it is studied for its capacity to stimulate the endogenous secretion of growth hormone (GH) and, downstream, insulin-like growth factor 1 (IGF-1). Its structural modification relative to native GHRH(1-44) is associated in the literature with improved stability against enzymatic degradation, making it a useful probe for studying pulsatile GH-axis signaling in vitro and in animal models. All mechanistic description here refers strictly to preclinical and in-vitro research contexts.
Research
- GHRH-GH-IGF-1 axis signaling in cell and animal models
- Neuroendocrine regulation of pulsatile growth hormone secretion
- Lipid and visceral adipose tissue metabolism in preclinical models
- IGF-1 downstream signaling pathways in vitro
- Metabolic and body-composition research models
- Peptide stability and analog structure-activity studies
- Analytical method development and assay reference standardization
Advantages
- Serves as a well-characterized GHRH-analog reference compound for in-vitro and animal-model studies of the GH axis
- Used in research models to probe stimulation of endogenous GH and IGF-1 signaling
- Enzymatically stabilized structure supports reproducible experimental conditions in the laboratory
- ≥98% HPLC purity with per-batch CoA supports consistent, comparable research results
- Lyophilized 10 mg format suitable for reconstitution and controlled dispensing in laboratory research assays
Safety
- This is a laboratory reagent supplied strictly for Research Use Only (RUO); it is not administered to humans or animals, and Peptworks offers no human or veterinary safety profile for it.
- It should be handled only by qualified personnel using standard laboratory practice for synthetic research peptides, following the storage, handling and purity information in the batch Certificate of Analysis.
- Any physiological effects reported for GHRH analogs in the broader scientific literature fall outside the scope of this Research-Use-Only supply and are provided by Peptworks neither as a safety characterization nor as guidance for use in humans or animals.
Ideal for
- Research laboratories and institutions studying the GHRH-GH-IGF-1 axis
- B2B resellers and distributors sourcing bulk research peptides from EU stock
- White-label brands building a catalog of research-grade GH-category peptides
- Analytical labs needing a GHRH-analog reference standard for method development
- Contract research settings requiring per-batch CoA documentation and traceability
This product is a laboratory reagent supplied strictly for research. It is not a medicine, food or supplement and is not for human or veterinary use. It must be handled by qualified professionals under laboratory conditions.
Frequently asked questions
Where can I buy Tesamorelin in bulk in the EU?
Peptworks is a B2B wholesale and white-label supplier with Tesamorelin (Tesamorelin acetate, 10 mg lyophilized vials) held in stock inside the EU. Orders ship intra-community in 3-5 business days with no customs. It is sold for Research Use Only to businesses, not to end users.
What is the wholesale price per vial for Tesamorelin?
Tesamorelin 10mg has two public per-vial prices: €79.90 in a 4-vial pack and €50.00 from 10 vials of this reference (box price). There are no volume tiers. Shipping is free on orders from €500 (€24.90 below), inside the EU with no customs.
Do you offer Tesamorelin as white-label?
Yes, in the white-label sense: Tesamorelin comes in unbranded vials, with no brand on the vial, so you can resell it under your own label. Peptworks does not print or apply labels. Every batch is tested by an independent lab and ships from EU stock with no customs.
What is the minimum order for Tesamorelin?
The minimum is a 4-vial pack per reference; from 10 vials of a reference the lower box price applies. Vials ship in boxes of 10. There are no volume tiers, and orders from €500 ship free.
How is the Certificate of Analysis (CoA) verified?
Every batch has an independent Certificate of Analysis covering HPLC purity (≥98%) and heavy metals. Each box carries a unique QR code that links to that specific batch's CoA, which you can authenticate through Peptworks.
How do I pay and how fast does it ship?
Payment is in crypto: USDC or USDT (Polygon or Base) or Bitcoin — paying in crypto is what keeps our prices this tight, with no card or bank fees. there is no card checkout on the site. Because stock is already inside the EU, orders ship intra-community in 3-5 business days with no customs clearance.
