MGF (5mg)

What is MGF (Mechano Growth Factor)?

Activates satellite cells — dormant stem cells in muscle tissue responsible for repair and growth.

Listed vial contents: 5mg. These are supplied quantities, not administration doses. Current pricing and availability are shown in the strength selector.

What mechanisms are being studied?

MGF is a 24-amino acid synthetic peptide corresponding to the C-terminal E-domain of the IGF-1Ec splice variant. It is naturally produced by muscle tissue in response to mechanical stress. MGF activates satellite cells — dormant muscle stem cells — via ERK1/2 phosphorylation, initiating their proliferation and differentiation into new muscle fibers.

What are the research questions?

• Muscle repair and hypertrophy: Primary application — activating satellite cells for muscle fiber repair and new muscle growth.
• Cardiac muscle repair: Activates cardiac progenitor cells similarly to skeletal muscle satellite cells.
• Age-related muscle loss (sarcopenia): MGF expression declines with age, contributing to impaired muscle repair capacity.
• Neuroprotection: Has shown neuroprotective effects in brain ischemia models.

What does the published work describe?

Goldspink G (Br J Sports Med 2005) — 25% muscle mass increase in mice over 3 weeks with local MGF injection. Yang SY, Goldspink G (FEBS Lett 2002) — MGF expression correlates with muscle hypertrophy response to mechanical overload.

What are the limits of this evidence?

The research described concerns the cited experimental materials and models, not proof that this supplied vial is a treatment. Cell or animal findings do not establish human benefits. Clinical findings, where cited, apply to the tested formulation and population; they do not validate this research product for human use.

How should I check lot documentation?

Match the product, strength and lot to an original analysis document. Literature describes experimental findings; it does not verify the contents of this inventory. Generated sample reports illustrate the reporting flow and are not evidence of testing, purity or accreditation.
