PEG MGF dosage chart

2 mg Vial

PEG MGF is dosed at 200 mcg–500 mcg daily via subcutaneous injection in educational protocols. A 2 mg vial reconstituted with bacteriostatic water yields about 0.667 mg/mL. This information is for research and educational use only.

Reconstitute: Add 3.0 mL bacteriostatic water (max vial capacity) → ~0.667 mg/mL concentration.
Typical daily range: 200–500 mcg once daily (gradual titration over 8 weeks).
Easy measuring: At 0.667 mg/mL, 1 unit = 0.01 mL ≈ 6.67 mcg on a U-100 insulin syringe.
Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles.

Dosing schedule

Week	Daily Dose (mcg)	Units (per injection) (mL)
Weeks 1–2	200 mcg	30 units (0.30 mL)
Weeks 3–4	300 mcg	45 units (0.45 mL)
Weeks 5–6	400 mcg	60 units (0.60 mL)
Weeks 7–8	500 mcg	75 units (0.75 mL)

Reconstitution steps

1Draw 3.0 mL bacteriostatic water with a sterile syringe.
2Inject slowly down the vial wall; avoid foaming.
3Gently swirl/roll until dissolved (do not shake).
4Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

Important Notes

Practical considerations for consistency and safety.

Use new sterile insulin syringes; dispose in a sharps container.
Rotate injection sites (abdomen, thighs, upper arms) to reduce local irritation.
Inject slowly; wait a few seconds before withdrawing the needle.
Document daily dose and site rotation to maintain consistency.
No clinical trials of PEG MGF have been completed; effects have been demonstrated in animal and cell models only.

How This Works

MGF is a splice variant of IGF-1 that is expressed in muscle tissue following mechanical loading or damage. Unlike systemic IGF-1, MGF acts locally to activate satellite cells and initiate muscle repair processes through its unique C-terminal E peptide domain. Pegylation of MGF extends its half-life, allowing for once-daily subcutaneous administration instead of the frequent local injections required for native MGF. Animal studies have shown that MGF analogues can enhance muscle regeneration, bone healing, and cartilage repair when administered over several weeks.

Potential Benefits & Side Effects

Observations from preclinical and cell-based research.

Animal studies demonstrate enhanced muscle, bone, and cartilage regeneration with MGF analogues administered over multiple weeks.
MGF promotes myogenic precursor cell proliferation and improves muscle repair in models of injury or depletion.
No human clinical trials have been completed; safety and efficacy in humans remain unestablished.
Generally well tolerated in preclinical models; mild injection-site reactions may occur with subcutaneous administration.

Lifestyle Factors

Complementary strategies for optimal muscle recovery and adaptation.

Combine with progressive resistance training to maximize muscle growth signals and satellite cell activation.
Maintain adequate protein intake (1.6–2.2 g/kg body weight daily) to support muscle protein synthesis.
Prioritize sleep (7–9 hours nightly) and manage training stress to optimize recovery and adaptation.
Consider timing around training sessions, though optimal timing has not been established in human studies.

Injection Technique

General subcutaneous guidance from clinical best-practice resources.

Clean the vial stopper and skin with alcohol; allow to dry.
Pinch a skinfold; insert the needle at 45–90° into subcutaneous tissue.
Do not aspirate for subcutaneous injections; inject slowly and steadily.
Rotate sites systematically (abdomen, thighs, upper arms) to avoid lipohypertrophy and tissue irritation.
Always use a new sterile needle and syringe for each injection; dispose of sharps in proper containers.

PEG MGF dosage FAQs

How much bacteriostatic water do you use to reconstitute PEG MGF?

Add 3.0 mL bacteriostatic water (max vial capacity) → ~0.667 mg/mL concentration. for a 2 mg Vial vial. Add the water slowly against the inside wall of the vial and swirl — never shake — until the powder fully dissolves.

What does the PEG MGF dosing schedule look like?

Weeks 1–2 — 200 mcg — 30 units (0.30 mL); Weeks 3–4 — 300 mcg — 45 units (0.45 mL); Weeks 5–6 — 400 mcg — 60 units (0.60 mL); Weeks 7–8 — 500 mcg — 75 units (0.75 mL). The full table above lists every step with matching syringe units.

What are the mixing steps for PEG MGF?

Draw 3.0 mL bacteriostatic water with a sterile syringe. Inject slowly down the vial wall; avoid foaming. Gently swirl/roll until dissolved (do not shake).

How should reconstituted PEG MGF be stored?

Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles..

How many insulin syringe units equal a PEG MGF dose?

Units depend on the water volume you used. Divide your target dose by the vial concentration to get millilitres, then multiply by 100 — 1 unit on a U-100 insulin syringe is 0.01 mL. The Spartan Peptides reconstitution calculator does this conversion for you.

Is PEG MGF approved for human use?

No. PEG MGF is sold and referenced strictly as a research chemical. Nothing on this page is medical advice and the material is not for human consumption.

Educational and research information only. Not medical advice, not for human consumption. Values are reference figures — always verify your own math with the reconstitution calculator.

On any insulin syringe, 1 unit = 0.01 mL, so unit counts above hold across brands.
