Frequently Asked
How do I reconstitute PEG-MGF?
Add 2 mL of bacteriostatic water to a 2 mg vial, injecting slowly down the inside wall. Swirl gently; never shake. This yields a concentration of 1000 µg/mL.
What is the recommended dose of PEG-MGF?
A typical research dose is 200 µg. Consult the ASCEND calculator for your specific vial concentration and draw volume.
How many doses are in a PEG-MGF vial?
A 2 mg vial reconstituted with 2 mL BAC water yields approximately 10 doses at 200 µg each.
How many IU is 200 µg of PEG-MGF on a syringe?
With a 2 mg vial reconstituted in 2 mL bacteriostatic water, the concentration is 1000 µg/mL. For a 200 µg dose: Volume = 200 µg ÷ 1000 µg/mL = 0.2 mL. Draw to the 20 line on a 100-unit insulin syringe. You can adjust these values in the ASCEND calculator for any vial size.
What does a PEG-MGF dosage calculator do?
A PEG-MGF dosage calculator converts your vial size and BAC water volume into an exact syringe draw in IU. Enter your vial strength (2 mg), reconstitution volume (2 mL), and target dose to get the precise line to draw on an insulin syringe.
What is the PEG-MGF reconstitution calculator formula?
Draw volume (mL) = Dose (µg) divided by Concentration (µg/mL). For a 2 mg vial with 2 mL BAC water: concentration = 1000 µg/mL. For a 200 µg dose, the ASCEND calculator gives the exact IU line on your syringe instantly.
Peptide Intelligence
What is PEGylated MGF and why is it PEGylated?
PEG-MGF is the IGF-1Ec splice variant with polyethylene glycol attached to extend its half-life. Native MGF has a half-life of only a few minutes; PEGylation extends this to several days, enabling once or twice-weekly dosing for muscle repair research.
When is the optimal timing for PEG-MGF administration?
PEG-MGF is typically administered following resistance exercise or injury, as MGF is naturally upregulated in mechanically stressed muscle. Post-workout administration within 30–60 minutes is standard in muscle satellite cell activation protocols.
How does PEG-MGF differ from IGF-1 LR3?
PEG-MGF primarily activates muscle satellite cells (myogenic precursor cells) for local muscle repair, while IGF-1 LR3 has broader systemic anabolic effects. PEG-MGF is considered more tissue-specific; some researchers use both in sequence for maximal muscle recovery protocols.
