Growth Hormone Secretagogues

MGF

Also known as: Mechano Growth Factor, IGF-1Ec, IGF-1 Ec

Research use only · not FDA-approved

Mechano Growth Factor is the C-terminal E-domain peptide derived from IGF-1Ec, a splice variant of insulin-like growth factor 1 that is expressed locally and transiently in skeletal muscle in response to mechanical loading or damage. After cleavage from the IGF-1 precursor, the 24-amino-acid MGF E-peptide acts independently of the IGF-1 receptor, helping activate quiescent satellite (muscle stem) cells to support muscle repair and hypertrophy. Synthetic MGF is the unmodified peptide and is degraded rapidly in body fluids; the related PEG-MGF kept in this directory is the pegylated form, in which polyethylene glycol (and typically a stabilizing D-amino-acid substitution) is attached to extend half-life. MGF is not FDA-approved and is a grey-market research compound with no controlled human efficacy data.

Typical dose range

Vendor-reported research use commonly 100-200 mcg per injection, local/subcutaneous; no validated human dosing

Half-life

Very short (minutes-scale) for unmodified MGF due to rapid degradation in plasma; the pegylated PEG-MGF variant is engineered for a substantially longer half-life

Common research uses

muscle growth and recovery research (research only)satellite-cell activation studies (preclinical)experimental tissue repair (research only)

Safety notes

Not FDA-approved for human use; sold as a research chemical only with no controlled human safety data. As an IGF-1-related growth factor it is prohibited at all times under the WADA Code (S2). Theoretical risks include effects on cell proliferation; purity and identity of grey-market product are unverified.

Reconstitution

Supplied as lyophilized powder; reconstitute with bacteriostatic water and refrigerate after reconstitution.

Multimodal graph-based fusion via image descriptions for few-shot open-set recognition

Few-shot open-set recognition (FSOR) presents unique challenges due to the limited labeled samples and the presence of unknown classes during inference.

RIXS reveals sub-20-femtosecond lattice relaxation around two core excitons in MgO and MgF<sub>2</sub>

Soft X-ray emission at the Mg L 2,3 edge of MgO and MgF 2 reveals weak continuous energy-loss tails (ELTs) adjacent to the elastic scattering lines. These ELTs are attributed to lattice relaxation around core excitons.

Montage-guided fusion network for long-term scalp electroencephalography seizure detection

Introduction Automatic seizure detection from long-term scalp electroencephalography (EEG) can reduce the burden of manual EEG review. However, multi-derivation EEG is commonly processed as a collection of input channels without explicitly modeling the structured relations defined by the bipolar montage.
