In short: Cagrilintide is a long-acting, acylated analogue of the hormone amylin and an unapproved investigational compound, supplied by Vexar Lab strictly for in-vitro laboratory research and not approved for human consumption. It is a current reference compound in amylin-receptor and metabolic research. Before ordering any peptide, research buyers should confirm purity of at least 99% by HPLC, identity confirmation by mass spectrometry, and clear batch numbering with a corresponding certificate of analysis (COA).

What is Cagrilintide?

Cagrilintide is a synthetic, long-acting amylin analogue developed by Novo Nordisk as a once-weekly, acylated peptide. It is described in the literature as a non-selective amylin-receptor agonist acting at calcitonin and amylin receptor complexes. It remains an investigational, proprietary compound: as of 2026 it is not approved by the FDA or EMA, and much of its development has focused on the combination with semaglutide known as CagriSema, which is also not approved. Researchers use cagrilintide as a tool to study long-acting amylin-receptor pharmacology.

What does the research investigate?

Published research, including Phase 2 and Phase 3 clinical programmes, has investigated cagrilintide’s effects on amylin-receptor signalling, food intake, body weight, and glycaemic control, both as a monotherapy and in combination with GLP-1 receptor agonists. Trials have also examined its role in bone metabolism. As an unapproved investigational drug, all reported effects are research findings only and do not establish safety or efficacy for any general human use; the compound is not authorised for therapeutic use in any market. Always read the primary sources directly.

Purity and quality: what research buyers should check

• Purity of at least 99% by HPLC — confirm the figure against the batch-specific COA rather than a generic specification sheet.
• Identity confirmation by mass spectrometry — the measured mass should match the expected molecular weight of the peptide.
• Batch numbering — every vial should trace back to a documented production batch and its analytical records.

Vexar Lab supplies Cagrilintide as a pack of 10 vials, ≥99% HPLC-verified, batch-numbered, with mass-spec confirmation.

In short: MOTS-c is a 16-amino-acid mitochondrial-derived peptide encoded within the mitochondrial 12S rRNA gene, supplied by Vexar Lab strictly for in-vitro laboratory research and not approved for human consumption. It is a widely studied tool compound in metabolic and mitochondrial-signalling research. Before ordering any peptide, research buyers should confirm purity of at least 99% by HPLC, identity confirmation by mass spectrometry, and clear batch numbering with a corresponding certificate of analysis (COA).

What is MOTS-c?

MOTS-c (mitochondrial open reading frame of the 12S rRNA type-c) is a short peptide notable for being encoded by mitochondrial DNA rather than the nuclear genome — one of the first peptides discovered to be produced this way. This finding helped establish that mitochondria actively signal to the rest of the cell through dedicated peptides. In research it is described as a regulator of cellular metabolism that circulates in the bloodstream and acts on metabolic tissues, making it a frequently used reference compound in studies of mitochondrial-to-nuclear communication.

What does the research investigate?

Pre-clinical literature has examined MOTS-c chiefly for its reported activation of the AMPK pathway, effects on glucose uptake in skeletal muscle, and modulation of the folate-methionine cycle. Because circulating levels are reported to rise with exercise in some studies, it is often referred to in the literature as an “exercise mimetic.” Animal research has explored its role in diet-induced metabolic dysfunction, insulin sensitivity, and age-related metabolic changes. These are investigational findings from cell and animal models and do not establish safety or efficacy for any human use. Always read the primary sources directly.

In short: Epithalon (also written Epitalon) is a synthetic tetrapeptide, Ala-Glu-Asp-Gly (AEDG), modelled on a pineal-gland peptide, supplied by Vexar Lab strictly for in-vitro laboratory research and not approved for human consumption. It is a widely cited tool compound in telomere and longevity research. Before ordering any peptide, research buyers should confirm purity of at least 99% by HPLC, identity confirmation by mass spectrometry, and clear batch numbering with a corresponding certificate of analysis (COA).

What is Epithalon?

Epithalon is a short four-amino-acid peptide bioregulator (Ala-Glu-Asp-Gly) developed by Vladimir Khavinson and colleagues, derived from study of the pineal extract epithalamin. As one of the simplest synthetic peptide bioregulators, it is often used as a reference compound in research on short peptides that are proposed to interact with DNA and gene-regulatory processes. Much of the foundational work was conducted at the St. Petersburg Institute of Bioregulation and Gerontology, with independent laboratories more recently revisiting its reported effects.

What does the research investigate?

In cell-culture and animal models, epithalon has been studied chiefly for reported activation of telomerase and telomere elongation in somatic cells, for effects on pineal melatonin rhythm and circadian function, and for changes in lifespan and age-related markers in model organisms. Some animal studies report extended lifespan without increased tumour incidence, and the literature also describes effects on immune-related signalling and various enzyme activities. The precise mechanisms remain uncertain and these are investigational pre-clinical findings that do not establish human safety or efficacy. Always read the primary sources directly.

Purity and quality: what research buyers should check

• Purity of at least 99% by HPLC — confirm the figure against the batch-specific COA rather than a generic specification sheet.

In short: PT-141 (bremelanotide) is a cyclic heptapeptide derived from the α-MSH analogue Melanotan II, supplied by Vexar Lab strictly for in-vitro laboratory research and not approved for human consumption. It is a well-characterised tool compound for studying melanocortin-receptor signalling in pre-clinical models. Before ordering any peptide, research buyers should confirm purity of at least 99% by HPLC, identity confirmation by mass spectrometry, and clear batch numbering with a corresponding certificate of analysis (COA).

What is PT-141?

PT-141 is a cyclic seven-amino-acid peptide that acts as a melanocortin-receptor agonist, with reported selectivity for the MC3 and MC4 receptor subtypes. It originated from work on α-melanocyte-stimulating hormone analogues at the University of Arizona, where Melanotan II was developed; PT-141 is a downstream, structurally distinct metabolite of that lineage. Its cyclic structure is reported to confer greater metabolic stability than linear α-MSH analogues. Because MC3R and MC4R are highly expressed in the hypothalamus and limbic system, PT-141 is frequently used as a reference agonist in central melanocortin research.

What does the research investigate?

Pre-clinical literature has used PT-141 to probe central melanocortin signalling, including MC3R/MC4R pharmacology, hypothalamic circuit function, autonomic modulation, and behavioural endpoints related to reward and arousal pathways in animal models. It is also cited in studies of blood-brain-barrier penetration by peptides. These are investigational findings from cell and animal research; they characterise receptor pharmacology and do not establish safety or efficacy for any human application. Always read the primary sources directly.

Purity and quality: what research buyers should check

• Purity of at least 99% by HPLC — confirm the figure against the batch-specific COA rather than a generic specification sheet.

In short: Tesamorelin is a synthetic 44-amino-acid analogue of growth hormone-releasing hormone (GHRH), supplied by Vexar Lab strictly for in-vitro laboratory research and not approved for human consumption. It is widely used as a tool compound for investigating the GH/IGF-1 axis in pre-clinical models. Research buyers should confirm three things before ordering any peptide: purity of at least 99% by HPLC, identity confirmation by mass spectrometry, and clear batch numbering with a corresponding certificate of analysis (COA).

What is Tesamorelin?

Tesamorelin is a stabilised analogue of human GHRH(1-44). Its structure is identical to native GHRH with a single modification — a trans-3-hexenoic acid group attached at the N-terminus — which is reported to slow enzymatic degradation and extend its functional half-life relative to unmodified GHRH. Mechanistically, it is studied as a GHRH-receptor agonist that acts on the anterior pituitary. Rather than introducing exogenous growth hormone, pre-clinical work describes it as amplifying the pituitary’s own pulsatile GH secretion. This makes it a frequently cited reference compound in studies of neuroendocrine signalling.

What does the research investigate?

Published pre-clinical and clinical literature has examined tesamorelin’s effects on the growth hormone/IGF-1 axis, on visceral adipose tissue, and on markers of lipid and glucose metabolism. In laboratory contexts it is used to probe GHRH-receptor pharmacology, pulsatile hormone release, and metabolic regulation. Tesamorelin is notable among GHRH analogues for having a substantial body of published study data, which makes it useful as a comparator. These findings are drawn from cell, animal, and controlled clinical research and do not establish safety or efficacy for any general human use. Always read the primary sources directly.

Purity and quality: what research buyers should check

• Purity of at least 99% by HPLC — confirm the figure against the batch-specific COA rather than a generic specification sheet.
• Identity confirmation by mass spectrometry — the measured mass should match the expected molecular weight of the peptide.
