PEG-MGF is heavier: the conjugated polyethylene glycol adds a variable mass (commonly a few kDa) on top of the peptide, so total mass depends on the PEG used. | 333.29 g/mol | | Common Vial Sizes | 2 | — | ## Price tracking Tracking PEG-MGF prices since April 22, 2026. Trend chart unlocks once we have price snapshots from more than one day. ## Price History 3 data points - Ion Peptide - Disguised Alpha - LB ### PEG-MGF: potential benefits - Increases satellite-cell and myoblast proliferation, expanding the cell pool available for muscle repair (in vitro and animal studies) - May accelerate muscle repair after exercise-induced damage or injury (preclinical) - Pro-survival, anti-apoptotic signaling reported in muscle and other cell types (preclinical) - Preclinical cytoprotection: MGF pretreatment improved cardiac function after experimental myocardial infarction (mechanism distinct from IGF-1R, NOT via fibroblast growth factor receptor) - Preclinical neuroprotection during cerebral ischemia - PEGylation is intended to extend native MGF's very short half-life to allow less frequent research dosing ### Cartalax: potential benefits - Joint and cartilage repair support - Connective tissue maintenance - Anti-aging effects on musculoskeletal system - Improved joint mobility ## Frequently asked ### What's the difference between PEG-MGF and Cartalax? PEG-MGF is a performance that peg-mgf is the pegylated form of mechano growth factor (mgf), a synthetic peptide corresponding to the c-terminal 24 amino acids of the unique e-domain of igf-1ec, an alternatively…. Cartalax is a recovery that mechanism of action cartalax's proposed mechanism is the khavinson short-peptide framework applied to cartilage: passive membrane permeation, nuclear import, and sequence-selective…. The two differ in mechanism, half-life (Native MGF: very short (minutes) due to rapid proteolysis. PEG-MGF: PEGylation is intended to extend this substantially (community estimates up to roughly 1 day), but there are no published human pharmacokinetic data to confirm a specific value. vs No published human or animal pharmacokinetic data for Cartalax. As a small (~446.5 Da) tetrapeptide, rapid plasma hydrolysis (on the order of minutes) is expected, consistent with other Khavinson short peptides, but this has not been directly measured.), and typical dose range. ### Which has the longer half-life, PEG-MGF or Cartalax? PEG-MGF has a half-life of Native MGF: very short (minutes) due to rapid proteolysis. PEG-MGF: PEGylation is intended to extend this substantially (community estimates up to roughly 1 day), but there are no published human pharmacokinetic data to confirm a specific value.. Cartalax has a half-life of No published human or animal pharmacokinetic data for Cartalax. As a small (~446.5 Da) tetrapeptide, rapid plasma hydrolysis (on the order of minutes) is expected, consistent with other Khavinson short peptides, but this has not been directly measured.. Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Which is cheaper, PEG-MGF or Cartalax? Lowest listed price on BodyHackGuide: PEG-MGF from $39.00, Cartalax from $58.85. Prices are pulled from the vendor listings tracked on BHG and change frequently. See the compare tables on each compound page for the current set of offers. ### Can you stack PEG-MGF and Cartalax? Stacking depends on mechanism overlap, safety profile, and goals. PEG-MGF and Cartalax should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data. Use the BodyHackGuide stack builder for a structured review before combining research compounds. ## See current vendor prices Listings from the vendors we track.
