How many units of PEG-MGF should I draw?

It depends on your vial size, BAC water, and dose. For a 2mg vial with 1mL BAC water, a beginner dose of 150mcg is typically 8 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to PEG-MGF?

The standard amount is 1mL of bacteriostatic water for a 2mg vial. More water gives a more dilute solution — easier to measure small doses. Less water means fewer injections per vial. Adjust the BAC water slider in the calculator to see how it changes your syringe units.

How long does a PEG-MGF vial last?

At a beginner dose of 150mcg 2x/week, a 2mg vial lasts about 13 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for PEG-MGF?

Most people use a U-100 insulin syringe (1mL / 100 units). For very small doses, a U-50 or U-30 syringe gives better precision. The calculator adjusts units automatically for whichever syringe you pick.

PEG-MGF Pharmacokinetics

Pharmacokinetics — Active Dose Over Time

t½ = ~48-72 hours (PEGylated); native MGF: ~5-7 minutes

After 1 half-life (3d): 50% remainsAfter 2 half-lives (5d): 25% remainsAfter 3 half-lives (8d): 12.5% remains

At a 200mcg dose: 50% = 100mcg remaining after 3d. Recommended frequency: 3x/week.

Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

PEG-MGF Dosing Protocol

Level	Dose / Injection	Frequency
Beginner	150mcg	2x/week
Moderate	200mcg	3x/week
Aggressive	400mcg	3x/week

Note: PEGylated form of Mechano Growth Factor (IGF-1Ec splice variant). The PEG moiety extends half-life from minutes to days. Inject post-workout near the trained muscle for localized effects. Do not combine with IGF-1 LR3 in the same injection window — stagger by several hours.

About PEG-MGF

PEG-MGF (Pegylated Mechano Growth Factor) is the PEGylated form of MGF, a splice variant of IGF-1 (specifically IGF-1Ec) produced in response to mechanical loading of muscle tissue. Native MGF has an extremely short half-life of approximately 5-7 minutes, making it impractical for therapeutic use. The addition of a polyethylene glycol (PEG) chain shields the peptide from enzymatic degradation and renal clearance, extending its half-life to approximately 48-72 hours. PEG-MGF activates quiescent muscle satellite (stem) cells, promoting their proliferation without triggering premature differentiation — a critical distinction from other growth factors like IGF-1 LR3, which primarily drives differentiation. This makes PEG-MGF a targeted tool for muscle repair and hypertrophy in preclinical research.
