MGF (Mechano Growth Factor) vs Hexarelin

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

MGF (Mechano Growth Factor)

MGF (Mechano Growth Factor) is a splice variant of IGF-1 that is produced locally in muscle tissue in response to mechanical stress. The non-PEGylated form has a very short half-life.

Hexarelin

Hexarelin is a potent synthetic hexapeptide growth hormone secretagogue. It provides the strongest GH release among GHRPs but is associated with rapid desensitization of receptors.

Side-by-Side Comparison

AspectMGF (Mechano Growth Factor)Hexarelin
MechanismActivates muscle satellite cells (stem cells) and promotes their proliferation without differentiation, priming them for fusion with existing muscle fibers during repair and growth.Acts as a ghrelin mimetic with high potency at the GHS receptor. Provides powerful GH release but receptor desensitization occurs faster than with other GHRPs, requiring cycling.
Typical DosageDue to extremely short half-life (minutes), typical protocols use 100-200mcg injected directly into target muscles immediately post-workout.Typical dosing: 100-200mcg administered 2-3 times daily for 4-6 weeks, followed by an equal off period to allow receptor resensitization.
AdministrationIntramuscular injection into trained muscles within minutes of workout completion. Must be used immediately after reconstitution due to instability.Subcutaneous injection. Cycling is essential to maintain effectiveness. Often used in short bursts rather than continuous protocols.
Side EffectsInjection site soreness, potential hypoglycemia, localized swelling. Short half-life limits systemic effects.Water retention, cortisol and prolactin increase, hunger (moderate), tingling, and potential blood pressure effects.
