Overview+

Hexarelin is a synthetic hexapeptide and a potent ghrelin-receptor agonist studied for its strong stimulation of growth-hormone release. Beyond the endocrine axis, it is also of interest in cardiovascular signaling research, where it acts through additional receptor targets.

History+

Developed by Mediolanum Farmaceutici under the codes EP-23905 and MF-6003, hexarelin was characterized in the 1990s for its growth-hormone-releasing activity. Later research examined its cardiovascular signaling through both the growth-hormone-secretagogue receptor and CD36, extending interest beyond its original endocrine profile.

Research findings+

Hexarelin has been studied in endocrine and cardiovascular models for GHS-receptor and CD36 agonism, growth-hormone-pulse stimulation, anti-apoptotic signaling, and cardiac-protection pathways. What sets hexarelin apart as a research tool is its dual reach into endocrine and cardiovascular signaling through more than one receptor. That makes it useful not only for growth-hormone studies but also for probing CD36-mediated and cardioprotective pathways in laboratory models.

Key areas of research
  • →Endocrine: GHS-receptor agonism, GH release
  • →Cardiovascular: CD36 signaling, cardiomyocyte protection
  • →Systemic: Anti-apoptotic and metabolic pathways

Frequently asked questions

What's the actual amount in each vial?+
Each vial contains the labeled mass of lyophilized peptide. Selected sizes appear above the price.
Are additional supplies needed?+
Reconstitution requires bacteriostatic water and appropriate sterile research labware – not included.
How long does a vial last?+
Sealed lyophilized vials are stable at −20°C for 24 months. Once reconstituted, store at 2–8°C and use within 28 days.
Does the product come with instructions?+
Each shipment includes the batch-specific Certificate of Analysis and recommended handling protocol.
What purity level is guaranteed?+
≥ 99% by reverse-phase HPLC (UV-220nm), confirmed via ESI-TOF mass spectrometry.
How should I store these products?+
Store sealed vials at −20°C, protected from light. Reconstituted solutions at 2–8°C.
What are peptides and how do they work?+
Peptides are short chains of amino acids that occur naturally in organisms, where they act as messengers in many biological systems. While some peptides have been developed for medical use, laboratory research focuses on understanding their activity at the cellular level, examining how they impact essential processes in vitro.
Do these products come with instructions?+
Products from Fast Track Labs are supplied without usage instructions, as they are designated solely for in vitro laboratory research and prohibited by law for human or animal consumption. Any misuse or unlawful application of these products will result in permanent denial of service.
How long do products take to deliver?+
Orders are typically processed and shipped within 24 hours, Monday through Saturday. Delivery times vary by location, but most domestic orders arrive within 3–5 business days. You'll receive tracking information as soon as your order ships.
