In short: MGF (Mechano Growth Factor, IGF-1Ec) is a splice variant of the IGF-1 gene studied in pre-clinical models for local muscle-repair signalling. It is supplied strictly for in-vitro laboratory research and is not approved for human consumption. Research buyers should confirm any material against three criteria before purchase: ≥99% purity by HPLC, identity confirmed by mass spectrometry, and clear batch numbering tied to a certificate of analysis.

What is MGF?

Mechano Growth Factor (MGF) is a splice variant of the IGF-1 gene — IGF-1Ec in humans, IGF-1Eb in rodents — that is transiently expressed in skeletal muscle, heart and bone in response to mechanical loading or tissue damage. It shares the mature IGF-1 sequence but carries a unique C-terminal E-peptide that research suggests has independent biological activity. It is handled in the laboratory as a lyophilised powder reconstituted for in-vitro work; a PEGylated form (PEG-MGF) is also used in research to extend stability.

What does the research investigate?

Pre-clinical and in-vitro research into MGF has focused on activation of muscle satellite (stem) cells, proliferation and differentiation signalling, and markers of muscle regeneration in rodent injury models. Studies of PEG-MGF report changes in satellite-cell number and myofiber cross-sectional area relative to controls. The absence of controlled human trials means these are investigational findings that do not establish human safety or efficacy. Always read the primary sources directly.

In short: AOD-9604 is a synthetic peptide derived from the C-terminal region of human growth hormone, studied in pre-clinical models for fat-metabolism signalling. It is supplied strictly for in-vitro laboratory research and is not approved for human consumption. Research buyers should confirm any material against three criteria before purchase: ≥99% purity by HPLC, identity confirmed by mass spectrometry, and clear batch numbering tied to a certificate of analysis.

What is AOD-9604?

AOD-9604 is a synthetic peptide engineered from the C-terminal segment of human growth hormone (approximately amino acids 177–191), an optimised analogue of the HGH fragment 176–191. It is handled in the laboratory as a lyophilised powder reconstituted for in-vitro assay work. Unlike full-length growth hormone, the fragment was designed in research settings to isolate a lipolytic domain.

What does the research investigate?

Pre-clinical research into AOD-9604 has examined lipolysis (fat breakdown) and lipogenesis (fat storage) in adipocyte and obese-animal models, with reports that it influenced fat metabolism without binding the GH receptor or raising IGF-1 in those models. A proposed mechanism involves β3-adrenergic receptor signalling. It is worth noting that later human obesity trials did not demonstrate statistically significant weight-loss outcomes, underscoring that animal findings do not establish human safety or efficacy. Always read the primary sources directly.

Purity and quality: what research buyers should check

• ≥99% purity by HPLC — confirm via the batch certificate of analysis (COA).
• Identity confirmed by mass spectrometry against the expected peptide mass.

In short: Hexarelin is a synthetic hexapeptide growth hormone secretagogue, structurally related to GHRP-6, studied in pre-clinical models for its action at both the ghrelin receptor (GHS-R1a) and the CD36 scavenger receptor. It is supplied strictly for in-vitro laboratory research and is not approved for human consumption. Research buyers should confirm any material against three criteria before purchase: ≥99% purity by HPLC, identity confirmed by mass spectrometry, and clear batch numbering tied to a certificate of analysis.

What is Hexarelin?

Hexarelin is a synthetic hexapeptide in the growth hormone-releasing peptide (GHRP) family, closely related in structure to GHRP-6 but modified for greater metabolic stability. Like other GHRPs it is a ghrelin-mimetic secretagogue and is handled in the laboratory as a lyophilised powder reconstituted for in-vitro assay work. A distinguishing feature studied in research models is its interaction with two receptor populations rather than one.

What does the research investigate?

Pre-clinical and in-vitro research into hexarelin has examined two pathways: GH-release signalling via the growth hormone secretagogue receptor (GHS-R1a), and separate cardiac-tissue effects attributed to the CD36 scavenger receptor in rodent and cell models. Animal models of myocardial ischaemia have been used to study CD36-mediated effects that appear, in those models, to operate independently of growth hormone release. These findings are drawn from cell cultures and animal studies only and do not establish safety or efficacy in humans. Always read the primary sources directly.

In short: GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide growth hormone secretagogue and the founding member of the GHRP family, studied in pre-clinical models for its action at the ghrelin receptor (GHS-R1a). It is supplied strictly for in-vitro laboratory research and is not approved for human consumption. Research buyers should confirm any material against three criteria before purchase: ≥99% purity by HPLC, identity confirmed by mass spectrometry, and clear batch numbering tied to a certificate of analysis.

What is GHRP-6?

GHRP-6 is a synthetic hexapeptide with the sequence His-D-Trp-Ala-Trp-D-Phe-Lys-NH₂ and a molecular weight of roughly 873 g/mol. Its two D-amino acids (D-Trp and D-Phe) confer resistance to enzymatic degradation. Characterised in 1984 from work by Cyril Bowers, it was the first synthetic peptide shown to release growth hormone dose-dependently through a mechanism distinct from GHRH, and it is the parent compound from which GHRP-2, hexarelin and ipamorelin were derived.

What does the research investigate?

Pre-clinical and in-vitro research into GHRP-6 has centred on its binding to the growth hormone secretagogue receptor (GHS-R1a) and the GH-release signalling this triggers in pituitary cell and animal models. Laboratory work has also explored GHRP-6 in appetite and food-intake signalling, and broader cytoprotective and tissue-repair questions in experimental models. These observations derive from cell cultures and animal studies only and do not establish safety or efficacy in humans. Always read the primary sources directly.

In short: GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide growth hormone secretagogue studied in pre-clinical models for its activation of the ghrelin receptor (GHS-R1a). It is supplied strictly for in-vitro laboratory research and is not approved for human consumption. Research buyers should confirm any material against three criteria before purchase: ≥99% purity by HPLC, identity confirmed by mass spectrometry, and clear batch numbering tied to a certificate of analysis.

What is GHRP-2?

GHRP-2 is a synthetic hexapeptide belonging to the growth hormone-releasing peptide (GHRP) family, the class of ghrelin-mimetic secretagogues first developed from structure-activity work by Cyril Bowers and colleagues. As a small synthetic peptide it is structurally distinct from growth hormone-releasing hormone (GHRH) and acts through a separate receptor pathway. In laboratory characterisation it is typically handled as a lyophilised powder and reconstituted for in-vitro assay work.

What does the research investigate?

Pre-clinical and in-vitro research into GHRP-2 has focused on its binding to the growth hormone secretagogue receptor (GHS-R1a) on pituitary somatotroph cells and the downstream signalling (PLC/IP3/Ca²⁺) associated with growth hormone release in animal and cell models. Laboratory studies have also examined GHRP-2 in the context of appetite and food-intake signalling in animal models, IGF-1 pathway modulation, and exploratory work on inflammatory markers in cultured cells.

In short: Sermorelin is a synthetic growth-hormone-releasing hormone (GHRH) analogue corresponding to the first 29 amino acids of native GHRH, supplied strictly for in-vitro laboratory research and not approved for human consumption. It is a common reference compound in pituitary and GH-axis signalling studies. Research buyers should require ≥99% purity by HPLC, identity confirmation by mass spectrometry, and clear batch numbering.

What is Sermorelin?

Sermorelin is GHRH(1-29)NH2 — the first 29 amino acids of endogenous growth-hormone-releasing hormone with an amidated C-terminus. It was developed as a shorter, synthetically accessible version of the full-length 44-amino-acid GHRH molecule, and is the shortest GHRH analogue in active research use, carrying no additional structural modifications. In laboratory systems it acts at pituitary GHRH receptors on somatotroph cells. It is offered here purely as a research reference material.

What does the research investigate?

Pre-clinical studies use sermorelin to probe GHRH-receptor signalling and the dynamics of the growth-hormone axis. In vitro work with anterior-pituitary cultures has reported dose-dependent increases in intracellular cAMP signalling associated with growth-hormone release, while animal studies have examined pulsatile GH secretion and downstream changes in circulating IGF-1. Its short half-life makes it a useful tool for studying pulsatile GH dynamics and pituitary responsiveness. These findings are pre-clinical and do not establish human safety or efficacy. Always read the primary sources directly.

In short: Mazdutide (also designated IBI362 / LY3305677) is a synthetic dual GLP-1 and glucagon receptor agonist peptide and an investigational compound, supplied strictly for in-vitro laboratory research and not approved for human consumption in the contexts addressed here. It serves as a reference material in metabolic receptor-signalling studies. Research buyers should require ≥99% purity by HPLC, identity confirmation by mass spectrometry, and clear batch numbering.

What is Mazdutide?

Mazdutide is a once-weekly peptide modelled on oxyntomodulin, a natural gut hormone, and engineered to act on both the GLP-1 receptor and the glucagon receptor. Its design aims to balance activation of the two receptors so that GLP-1 effects are retained while glucagon-driven changes are managed. It has been studied in clinical trials for metabolic conditions and remains investigational in most jurisdictions; any regional regulatory approvals do not authorise its use as a research chemical. Vexar Lab supplies it only as a laboratory reference material.

What does the research investigate?

Pre-clinical and early-phase studies have examined how mazdutide’s balanced GLP-1/glucagon receptor activity relates to energy metabolism, glucose handling and body-composition endpoints in cell and animal models, with some multi-omics work exploring metabolic signalling pathways. As an investigational compound, these observations are exploratory and do not establish human safety or efficacy outside controlled, approved clinical settings. Always read the primary sources directly.

Purity and quality: what research buyers should check

• ≥99% purity by HPLC (confirm via the batch certificate of analysis, or COA)
• Identity confirmed by mass spectrometry
• Batch numbering for full traceability

In short: Survodutide (also designated BI 456906) is a synthetic dual glucagon and GLP-1 receptor agonist peptide and an unapproved investigational compound, supplied strictly for in-vitro laboratory research and not approved for human consumption. It serves as a reference compound in metabolic receptor-signalling studies. Research buyers should require ≥99% purity by HPLC, identity confirmation by mass spectrometry, and clear batch numbering.

What is Survodutide?

Survodutide is a 29-amino-acid peptide based on glucagon, engineered with several substitutions drawn from GLP-1 and exendin-4 and a C18 fatty-diacid chain that, in pharmacological studies, supports an extended half-life. It was developed by Boehringer Ingelheim and Zealand Pharma as a dual agonist of the glucagon and GLP-1 receptors. As an investigational drug candidate that has been studied in clinical trials for metabolic conditions, it is not an approved medicine and is offered here only as a laboratory reference material.

What does the research investigate?

Pre-clinical and early-phase studies have explored how survodutide engages the glucagon receptor and the GLP-1 receptor, and how this dual activity relates to energy expenditure, food-intake signalling and hepatic metabolism in cell and animal models. Some work has examined neuronal regions associated with appetite regulation. Because survodutide remains an unapproved investigational compound, these findings are exploratory and do not establish human safety or efficacy. Always read the primary sources directly.

In short: Selank is a synthetic heptapeptide derived from the natural immune fragment tuftsin, supplied strictly for in-vitro laboratory research and not approved for human consumption. It is widely used as a reference compound in neuropeptide and behavioural-model research. Research buyers should require ≥99% purity by HPLC, identity confirmation by mass spectrometry, and clear batch numbering for traceable results.

What is Selank?

Selank is a heptapeptide developed by the Institute of Molecular Genetics of the Russian Academy of Sciences in collaboration with the V.V. Zakusov Institute of Pharmacology. It is based on tuftsin, a naturally occurring tetrapeptide (Thr-Lys-Pro-Arg) produced by enzymatic cleavage of immunoglobulin G. The tuftsin fragment was extended at the C-terminus with three L-amino acids (Pro-Gly-Pro) to improve metabolic stability and prolong its activity in experimental systems. In Russia it has been studied as an anxiolytic, but elsewhere it remains an unapproved research compound.

What does the research investigate?

Pre-clinical studies have examined Selank’s interactions with GABAergic, serotonergic and BDNF-related signalling in cell and animal models, alongside reported immunomodulatory and enkephalin-stabilising effects. Some rodent work has investigated whether Selank modulates GABAergic tone through indirect or allosteric mechanisms rather than direct receptor binding, and has looked at anxiety-like behaviour and cognition in standard test paradigms. These findings are exploratory and do not establish human safety or efficacy. Always read the primary sources directly.

In short: IGF-1 LR3 (Long R3 IGF-1) is a synthetic, modified analogue of insulin-like growth factor 1, supplied strictly for in-vitro laboratory research and not approved for human consumption. It is used as a reference compound in cell-signalling and growth-factor studies. When sourcing it for research, buyers should insist on ≥99% purity by HPLC, identity confirmation by mass spectrometry, and clear batch numbering so results are traceable.

What is IGF-1 LR3?

IGF-1 LR3 is an engineered variant of human IGF-1, an 83-amino-acid peptide compared with the 70-amino-acid native molecule. It carries an N-terminal extension of 13 residues and a substitution of glutamic acid with arginine at position 3 — the “R3” in its name. Together these modifications sharply reduce its affinity for IGF-binding proteins (IGFBPs), which in laboratory systems extends its apparent stability relative to unmodified IGF-1. It was originally developed as a research tool for studying IGF-receptor signalling without the confounding influence of binding-protein interactions.

What does the research investigate?

Pre-clinical work with IGF-1 LR3 is largely confined to cell culture and animal models. In vitro studies using myoblasts, fibroblasts, adipocytes and neuronal cells have examined how the analogue interacts with the IGF-1 receptor to influence proliferation, differentiation, protein-synthesis signalling, glucose uptake and cell-survival pathways. Reports describe activity at lower concentrations than native IGF-1, attributed to reduced IGFBP sequestration. Controlled human data are very limited, and these pre-clinical observations do not establish human safety or efficacy. Always read the primary sources directly.

Purity and quality: what research buyers should check

• ≥99% purity by HPLC (confirm via the batch certificate of analysis, or COA)
