    Eloralintide: Metabolic / Fat Loss research guide

    In short: Eloralintide (LY3841136), a selective, long-acting amylin receptor agonist engineered for once-weekly subcutaneous obesity research, with AMY1R-preferring pharmacology. It is studied in preclinical (cell and animal) research and is supplied strictly for laboratory use, not for human or clinical use.

    Not medical advice. Eloralintide is a research compound. This guide does not provide dosing, diagnosis, therapy recommendations, or claims about effects in humans.

    What to know first

  • Selective amylin receptor agonist — preferentially activates human AMY1R over the calcitonin receptor and AMY3R in vitro
  • C20 fatty-diacid / di-γ-glutamate acylation enables albumin binding for once-weekly subcutaneous dosing
  • Cys2–Cys7 methylene-thioacetal bridge stabilises the amylin scaffold against degradation
  • Reduces caloric intake through amylin-pathway satiety signalling, a mechanism distinct from GLP-1

    What Eloralintide is

    Eloralintide (LY3841136) is a selective, long-acting amylin receptor agonist engineered for once-weekly dosing, with an amylin-pathway appetite mechanism complementary to GLP-1 receptor agonists.

    One-paragraph overview from our research datasheet. Still scientific, but faster to read than the full mechanism list below.

    Research contexts

    Peer-reviewed papers discuss Eloralintide in specific lab settings. The points below reflect research questions, not health claims.

    Research vs. personal use: Literature describes experiments in cells and animals. That is distinct from real-world use. Our products are for laboratory research only.

    Typical study contexts

  • Incretin pathways, food intake and glucose handling in rodent models.
  • Some drug-class molecules have clinical trials. Those are distinct from catalogue research use.
  • Selective amylin receptor agonist — preferentially activates human AMY1R over the calcitonin receptor and AMY3R in vitro.
  • C20 fatty-diacid / di-γ-glutamate acylation enables albumin binding for once-weekly subcutaneous dosing.
  • Cys2–Cys7 methylene-thioacetal bridge stabilises the amylin scaffold against degradation.
  • Reduces caloric intake through amylin-pathway satiety signalling, a mechanism distinct from GLP-1.
  • Why Metabolic / Fat Loss research matters

    Metabolic peptides are studied for appetite signals, incretin pathways and energy balance. Literature emphasises mechanisms, not lifestyle advice.

    Mechanisms (technical review)

    Our datasheet lists mechanistic themes from preclinical work. These are research endpoints, not health claims.

  • Selective amylin receptor agonist — preferentially activates human AMY1R over the calcitonin receptor and AMY3R in vitro
  • C20 fatty-diacid / di-γ-glutamate acylation enables albumin binding for once-weekly subcutaneous dosing
  • Cys2–Cys7 methylene-thioacetal bridge stabilises the amylin scaffold against degradation
  • Reduces caloric intake through amylin-pathway satiety signalling, a mechanism distinct from GLP-1
  • Phase 1 proof-of-concept: well tolerated with minimal gastrointestinal adverse events
  • Reported Phase 2 obesity programme: clinically meaningful weight reduction with favourable tolerability
  • Lab handling & preparation

  • Storage: Lyophilised powder: store in freezer (−20 °C). Reconstituted: refrigerate 1–6 °C, away from sunlight. Use within the validated stability window for the specific batch and formulation.. See the storage guide.
  • Research dosing context: Literature typically discusses Reported only as published research context — not a recommendation. Once-weekly subcutaneous injection in published research Eloralintide is protracted for once-weekly subcutaneous administration and was titrated over several weeks in the published clinical programme. Exact escalation schedules are model- and study-specific and are not reproduced here as a protocol. Research use only — not for human use.
  • Preparation: Follow the reconstitution guide. Confirm volumes with the calculator.
  • Purity check: Use the COA reading guide and the published Eloralintide Certificate of Analysis.
  • Common Questions People Are Asking

    What is eloralintide and how does it work?

    Eloralintide (LY3841136) is a selective, long-acting amylin receptor agonist. It engages the amylin satiety pathway — hindbrain and hypothalamic appetite circuits — to reduce caloric intake, and in vitro it preferentially activates the human AMY1R receptor over the calcitonin receptor and AMY3R subtype. A lipid side chain at Lys26 (two γ-glutamate residues plus a C20 fatty diacid) binds serum albumin to extend its duration of action for once-weekly research dosing.

    How is eloralintide different from cagrilintide?

    Both are long-acting amylin analogues, but cagrilintide is a non-selective agonist across the amylin receptor family and the calcitonin receptor, whereas eloralintide is reported to be selective — preferentially activating the AMY1R amylin receptor. That selectivity is the main design difference between the two research peptides.

    How is eloralintide different from a GLP-1 agonist?

    GLP-1 agonists such as semaglutide activate the GLP-1 (incretin) receptor. Eloralintide activates the amylin receptor pathway. The two systems are distinct satiety circuits, which is why eloralintide has been studied both on its own and as a complement to incretin therapy.

    What does the research on eloralintide actually show?

    Published Phase 1 proof-of-concept research reported that once-weekly eloralintide was well tolerated with minimal gastrointestinal adverse events, and a subsequently reported Phase 2 obesity programme described clinically meaningful body-weight reduction with favourable tolerability. These are descriptive research findings for an investigational compound, not outcomes promised for any use of this research-grade material.

    Is eloralintide approved or legal?

    Eloralintide is an investigational compound (LY3841136) and is not an approved medicine in any jurisdiction. The material supplied here is unapproved, research-grade laboratory material sold strictly for in-vitro and preclinical research use only — not for human use.

    How is eloralintide reconstituted and stored?

    Keep the lyophilised powder at −20 °C in the freezer. Reconstitute with bacteriostatic water by directing it down the vial wall rather than onto the powder, then swirl gently — do not shake. After reconstitution, refrigerate at 1–6 °C and protect from light. Avoid repeated freeze–thaw cycles, which can damage the fatty-acid tail.

    Is this page medical advice? Can I use Eloralintide for my health?

    No, and no. This article is educational only. We do not provide dosing, medical recommendations, or health claims. Our products are sold strictly for laboratory research, not for personal use of any kind.

    Where do I find Eloralintide specs, purity certificates and pricing?
